stock market essays

stock market essays Prior to the stock market crash in 1929 and Black Thursday, a day which meant financial ruin for much of America, the U.S Economy was experiencing a great boom. The stock market, a growing trend in the life of Americans, allowed almost every man to experience the American dream. Investing was something that almost every person could do, the thought of putting in a few hundred dollars one day and waking up the next morning with twice as much money as you had put in amazed people. Once they started they couldnt get enough. At the beginning of the 1920s approximately 1.5 million citizens participated in the stock market but at the close of 1928 survey s said the about 17million had taken interest in the stock market. Because of their success and that of so many others, people could not possibly see how the stock market could fail, they watched its growth day by day and saw themselves grow more and more wealthy. This is not to say however that no one paid attention to the increasing amo unt of warning signs. Many noted that the pace at which prices were rising could be potentially dangerous, however when they tried to warn the public, people thought they were crazy for thinking this amazing time of wealth and prosperity could come to a devastating end. In the 1920s playing the stock market became a sort of national sport, people who had never invested in anything or prior to the 20s had never even heard of the stock market were buying and selling in hopes of getting rich quick. Brokerage firms became a common thing with advertisements and competition for lowest interest and down payments of as low as 10%. This further added to the madness of the times. What the average person didnt understand however, was that the stock prices did not reflect the real values of the shares or how much the companies were worth. Because of this, people spent their entire savings on stocks and when the bear market began...

Small Group Project - Essay Example The Ethics Review Committee under the chairmanship of the Compliance Officer is responsible for setting these ethical standards. After review of existing codes of conduct and related laws and regulations, the following codes of conduct applies to all management and employees of ECG, and are accountable for complying with this code of conduct: Adherence to applicable laws and regulations All employees in all ranks of the company must adhere to the legal requirements of the American government and countries that ECG conducts business. They must also adhere to the regulations of local authorities and commands that affect the company or its line of business. The laws and regulations that affect ECG are many; therefore, the company will provide guidelines on certain laws. The Compliance Officer will be available to answer any questions pertaining all laws that can affect the firm or its operations (Bacher, 2007). Conflict of interest This results when personal interests of employees and d irectors clash in any way with the interests of the firm. Despite having the right to engage in personal investments, enjoy private relationships and maintain normal business courteousness, employees, and management of ECG must not engage in activities or interests that may hinder their job responsibilities. Conflict of interest may also result when a member of staff pursues interests and actions that may negatively influence their performance. According to Hansen (2010), conflict of interest may also result when an employee, director or family members receive inappropriate gifts or benefits due to their relationship with the firm, whether the gain is from the firm or a client. Examples of conflict of interest are credit, guarantees for credit to employees and members of their families. Federal laws criminalize loans to executives and top management (Hansen, 2010). Working concurrently for a competitor, supplier or client amounts to a conflict of interest. Despite the fact that it i s not always easy to determine a conflict of interest, it is the firm’s policy to forbid such conflicts whenever feasible. Conflicts of interests may not be obvious in all circumstances; therefore, employees are advised to consult with the compliance officer whenever questions arise. Privacy All members of staff of all ranks at ECG must ensure the discretion of information entrusted to them by the firm, its clients, or suppliers except when admission is demanded by the firm, or required by laws and regulations or a court order. Classified information includes, but not confined to non-public information that may be utilized by opponents or injurious to the firm or its clients when revealed. Whenever possible, all members of staff must seek the guidance of the Compliance Officer if they believe that they have a lawful responsibility to divulge private information. Fair dealing Every member of staff in the company must strive to transact in a fair manner with the firm’s c lients, colleagues, and business competitors. No one should take undue advantage of the other through manipulation, misuse of privileged information, suppression, falsification of true facts and blackmail among other acts of unfair practice. Abusing trade secret information that was retrieved without owner’

Critical - Literature review Example 6.5 million and a medium enterprise can have up to 250 employees with a turnover of ?25.9 million. (BIS, 2011). SMEs are not only playing a significant role in the economy of United Kingdom but they are also major contributor in reducing the unemployment in the country. â€Å"Small and medium sized enterprises (SMEs) are an important part of UK economy. Out of nation 4.3 million business enterprises 99% are SMEs, accounting for well over half of the employment (58.9%) and turnover (51.9%).† (Dyerson & Hari, 2008, p. 139). Today, adoption of IT or Information and Communication Technology (ICT) by SMEs is not an option but a compulsion and business requirement. Businesses cannot afford to live and exit in isolation rather they have to integrate themselves with all new technologies that happened to exist and prevail in the society. The impact of information technology on the society has instigated new domains and horizons of information technology in the SMEs businesses and aware ness has begin to increased among European states some two decades back with the invent of internet and information explosion. â€Å"Earlier EU policies in support of Small and Medium Enterprises (SMEs) tended to focus on their role in creating employment. Over the past decade, there has been a pronounced shift to encourage greater SME participation in the information society and increased policy interest in the role that SME may play in innovation.† (Stanford-Smith, Enrica & Mireille, 2002, p.987). Apart from the size of an SME, the significance of an information technology framework is unquestionable for its existence, operation and growth. The role of IT in any business is multi faceted and it may range from internal operations and data repositories to eMarketing and eCommerce. The globalization of businesses has necessitated the induction of tools and trade of information technology into the SMEs all over the world. The strategic importance of SMEs in the economic growth of a country has grown multi times and governments try to enhance and boost economic escalation through the growth of SMEs to achieve sustainable economic strength. The adoption of information technology by SMEs is the tactical side of this strategic objective. Therefore, the governments not only encourage the use of technology but also enforce the use of these technologies to ensure better management and to guard public interest through IT enabled services by SMEs. These efforts were not limited to individual states but were also collaborated internationally by organizations like OECD. An early example of these steps includes the establishment of â€Å"Technology Development Centers (TEKES) in order to assist SMEs in planning development programs which include new technology and international cooperation.† (OECD, 1998, p. 82). United Kingdom being a member of OECD has been playing a pivotal role in the growth of SMEs and thereafter in the strengthening process of the SMEs wh ich includes but not limited to the adoption and encouragement of information technologies in these businesses. â€Å"Here again the operations are concentrated on the OECD countries and the main sectors include: technical and engineering studies, agro foods, chemicals, parachemicals and pharmaceuticals, information technology and electronics.† (OECD, 1998, p. 83). Threats and challenges always come bundled with the adoption of any technology and the information techn

Differences Between Intergovernmentalism And Constructivism Regarding The Eu Politics Essay

Differences Between Intergovernmentalism And Constructivism Regarding The Eu Politics Essay When considering these two theories in defining approaches to describe the European Union, we face the debate of agents versus structures. A constructivist approach means that it considering individual actors inside the structures in which they operate to have a significant impact on shaping their identity and behavior. Moreover, constructivism conceives of structures not only as material, but also social. Furthermore, these structures are not only constraints on behavior. Actors environment has a constitutive effect on actors identities on the basis of which they conceive their interests (Sedelmeier, 2005). Clearly, constructivism then takes into account the social factor, the one ignored by rational theory of maximum utility. For the EU, this means that it is not only an economic environment, one based on a materialistic approach. In fact, it is a cultural and social environment which shapes actors identities and interests (Sedelmeier, 2005). For constructivists the claim is that t hey study the integration of the European Union as a process (Cini, 2007). For constructivists then the focus becomes the formation, origins and evolution of identities, behavior related to languages and its role in political discourse, the role of social institutions etc. When we talk about constructivists we should see how the behavior regarding evolution of economic units, political institutions etc. emerges not because of material differences emerging in the economy but because of the process of emerging European identities (Cini, 2007) and the role social factors such as language , ideas and societal norms in these emerging identities. The liberal intergovernmentalist (LI) approach is based on political bargaining of states between governments, as in the case of treaties and reforms. In this approach, the power does not rest in social behavior or agents; in fact it is the political elite which has the power to improve interstate relations. The interaction then is between two forces; the member states and the EU Councils. In other words, This generally involves a two-stage process of negotiation. First, governments must resolve the policy problems that confront them; taking decisions to that effect; and only after that do they try to reach agreement on institutional mechanisms which would allow them to implement those decisions (Cini, 2007). As mentioned before, the political elite, meaning the governments of the member states are the main actors and the EU remains a forum for bargaining (Akiba, Fukuda, 2003). This theory holds that only the member state governments have the autonomy and can design the institutional system of the EU (Akiba, Fukuda, 2003). The limitations that this approach faces, especially when compared to constructivism is the fact that both theories slightly undermine the pace and the extent of the integration process and the autonomy that the EU has gained over the years in the sense that it has been increasingly ratifying treaties which have given more power to the Union.

Constructing the Path to Eastern Enlargement. Manchester University Press. How do Multi-Level Governance understandings of the EU describe, and explain the advent of, the present EU political system? When discussing the integration of the EU as an institution, the arguments between intergovernmentalists and constructivist, as well as supranationalist, federalist and confederalist approaches are somewhat diminished by the theory surrounding multi level governance of the EU; indeed, it has given way to the fact that the EU operates more as a single European Regime or European polity (Akiba, Fukuda, 2003). Multi level governance considers the role of the State in decision making as important, but not entire. In fact, decision making competencies are shared by actors at different levels rather than monopolized by national governments (Hooghe, Marks, 2001). This of course means that the decision making rests with the supranational institutions- the European Parliament, European Commission and the European Court. These institutions have independent influence in policy making (Hooghe, Marks, 2001). The two other important factors which are taken into account by multi level governance ar e the collective decision making process; i.e. policies enforced across the EU without wholehearted from all the national states and the sharing of control and autonomy relating to domestic politics between national governments and supranational institutions. This obviously refers to the fact that politics at the international and domestic level are greatly interconnected, a theory on which the multi level governance model is based. One of the examples of multi level governance and the perceived limited autonomy of the nation state in the EU is displayed by the majority voting system in the EU Council of Ministers. This voting can be on issues relating to internal trade, the environment, research policy (Hooghe, Marks, 2001). So in relation to the definitions discussed above, how would a multi level governance system explain the EU of today, and secondly, why would such a system be supported considering that it is taking power away from national actors and placing it with bodies at a supranational level? The answer is to consider the other actors present in nation states who might on one hand affect policy making, actors such as pressure groups and interest groups. The Council of Ministers is only represented by governments, not other actors. This might be looked on as an advantage by national governments in policy enforcement. Secondly, the EU itself has huge arenas of policy making and regulation under its umbrella, a most important one being trade. The trade benefits that member states receive are a result of greater integration of the European market. The concept of multi level governance is parallel to that of integration but analyzed differently because it focuses more on the various territorial lev els policy making has stretched over and how authority has shifted. There has been a drift of authority from the national to the European level which forces us to think of it as a political system across multiple levels including national and subnational arenas of action as well as the institutional environment of Brussels (Cini, 2007). Parallel to integration, we can see that the governance itself rests with multiple bodies of policy making and legislation, in the form of the evolution of the EU from a mere economic body to that of an organization consisting of its own Parliament, a Court (ECJ) and a Council of Ministers, all far reaching institutions that a single treaty establishing a European Coal and Steel Community. The idea behind this argument rests in the framework with which Europeanization scholars define the process of integration and the institutional changes taking place in the EU. The focus has shifted from thesis defining the framework to closely analyze the causal relationship surrounding the procedural changes, for instance, that of EUs domestic impact. It might be termed as a second generation of European studies (Gualini, 2004). The stress however, has recently shifted from policy at the international level to the way in which integration has affected national governments (Archer, 2008). The rationale behind this shift is the question that how European integration has affected domestic administrative practices and structures (Archer, 2008). This is more of a top-down approach toward Europeanization (Borzel, Risse, 2003). It is necessary to see the way Europeanization has affected domestic policies and institutions because it helps in understanding the integration process better bec ause according to one theory, policies enacted by the European Union must create some misfit in the administrative policies on a domestic level and this I one reason why change or adaotaion takes place on the domestic level (Borzel, Risse, 2003). This opinion is supported by rational choice institutionalism, simple that the process of change is initiated by greater distribution of power among the domestic administrative powers because interest groups might find opportunities in EU policies which could provide them with ways to pursue their own interests, if only they recognize such opportunities. Secondly, it also suggests that Europeanization leads to domestic change through a differential empowerment of actors resulting from a redistribution of resources at the domestic level (Borzel, Risse, 2003). The distribution of power is one reason why theorists have shifted from analyzing Europeanization in theory only, but in fact, have concentrated in recent times to see what extent chang e at the domestic level has been brought around by the process of Europeanization. The second way in which domestic change has been analyzed is through the lens of the constructivist perspective or logic of appropriateness. In this case, European policies and norms affect domestic processes by exerting adaptational pressures (Borzel, Risse, 2003) through change agents and other informal actors in the political processes. This is also supported by the collective learning process and connects more with the opinion of how new identities are formed through collective learning and social change. Essentially it is important to note that Europeanization as a policy offers new standards of policy to be implemented on the domestic level through political processes of implementation which in turn affects polity which affects domestic-level institutions, e.g. judiciary, public institutions, economic institutes etc. As one analyst puts it, The issue is no longer whether Europe matters but how it matters, to what degree, in what direction, at what pace, and at what point of tim e (Borzel, Risse, 2003). This is the reason through which the European Union, less as a policy and more as an institute of political change at the domestic level, is studied to understand the causal mechanisms of change.

Multi-level Governance Political Change. Ashgate Publishing. Why has the EU relied so much on economic integration to deepen the integration process as a whole? In 1951 the Treaty of Paris established the European Coal and Steel Community, one of the first formal steps taken toward European integration. Robert Schuman, the French Foreign Minister at that time was of the opinion that a united Europe was essential for peace in the region. The reason why EU has relied so much on economic integration depends mostly on the objectives of integration. After a war torn Europe, the idea was to rebuild Europe and also to defend against a future war which would serve as a destabilizing and destructing force for all of Europe. Economic integration was, and is, a rationale to serve a higher purpose, which is both economic and political (Molle, 2006). The economic integration would mean that the states would rather serve as a collective economic entity than an individual one. The benefits of this are increasing chances of peace and security in the reason because economies are interdependent. Greater dependence on each other economically means that chances of armed conflict between them would be minimal (Molle, 2006). The framework for the European Union can be said to have laid down when the Marshall Plan was introduced with the objective of the reconstruction of Western Europe. The introduction of the though of a unified European Steel production body thus was seen by both Schuman and Monnet as a realistic way in which conflict could be avoided. In Schumans word, the solidarity in the production thus established will make it plain that any war between France and Germany becomes not merely unthinkable but materially impossible (Jovanovic, 2005). In other words, the objective of peace is much more easily obtained when economies are linked together. Another important factor which proved once again the success of economic integration, relatively to integration progress in other areas, was the abolishment of all internal tariffs. This took place approximately a year and half before the Treaty of Rome was ratifies (Jovanovic, 2005). The result was economic benefits which ranged over a variety of industries, exports and imports and was the main attractive feature which cause Britain to apply for membership to the EC. Economy, it was seen, was a core feature which resulted in expansion of the EU and caused potential member states to right their situations, to improve their economic performance to be eligible to be apart of the EU. The arguments which have been used by pro-integration forces have therefore been focusing on the benefits obtained from economic integration, namely, increase in welfare by an increase in GDP per capita. A common economic ground formed on the basis of integration gives way to common policy ideals or support of policies which would strengthen, not weaken, the economic integration and vice versa. The Treat of Lisbon came into effect as a result of the global financial crisis and what it meant for the economy of the EU as a whole. The purpose was to control the situation financially inside the EU markets to promote financial stability and to offer security against unstable financial markets in whatever way possible. Since the monetary and financial markets of the EU are connected through means of a common currency, i.e. the Euro, financial crisis has the power to economically destabilize the entire region and there should be safeguards to minimize this threat. As a result, a European Financial Stability Facility (EFSF) and a European Stability Mechanism (ESM) has been set up to provide financial aid packages to countries severely affected by the financial crisis. For changes introduced in the European political sphere, the Lisbon Treaty takes into account the difference between delegated and executive acts, a distinction which was not considered by previous Treaties (Ponzano, 2008). Overall, this change means that the European Parliament has been granted a much stronger role than before whereby the Commission takes responsibility for delegated acts under the direct control of the European Parliament and the Council, giving each of the possibility of opposing the measure or revoking the delegation (Griller, Ziller, 2008). The second important political change the Treaty brings about is the double majority voting in the Qualified Majority Voting System in the European Council. The European Council also gains the status of a full European Union institution. The result of course, shows that the Lisbon Treaty granted more powers to the European Parliament, followed by the European Council. The Treaty of Lisbon has its roots in the failed ratification of the Constitutional Treaty. Establishing a Constitution for Europe has been a long-term shadow over European integration, a step that not many of the member states have been willing to take. Some questions put forth by Piris show considerable insight into the Lisbon Treaty and the circumstances surrounding it. For instance, is the Lisbon a mere repackaging of the Constitution of Europe (Piris, 2010)? Indeed the Lisbon Treaty has granted powers to the Parliament, the Court of Justice and the Commission to ensure greater balance of power in the EU. Secondly, the European Parliament, along with the national Parliaments of member states have been given the possibility of intervening directly in the EU legislative process (Piris, 2010). It definitely provides national Parliaments enough power to affect legislative process in the EU. A major difference however, between the Lisbon Treaty and the Constitutional treaty is the aba ndonment of transforming the EU into a federal body. That objective, according to Piris, has been fully deserted to be replaced by Euro-sceptic elements which to some extent limit the power of the EU.

Clothes Make a Man

It is said that we can judge a man’s character from his dress; But it’s not always so. Dress can only help us to a certain extent in knowing the broad facts of a man’s character. A man who wears a costly dress is necessarily a man of lavish habits. On the other hand, a man who wears tattered clothes is not necessarily a man of miserly habits. He may be do so only due to his financial limitations. Yet it is true that in some cases dressserves as a useful index to the character of a man. Some common examples, from which we can get some idea of a man’s character from his dress, are given below. We daily come across such persons as put on clothes of loud colours. We find them dressed in gaudy colours. They wear bushshirts printed withThe faces factors and actresses. So, is the case with their shoes. Shoes withdifferent designs on them are liked by them. We can easily know thecharacter of such people by looking at the way in which they dress. Suchpeople, if we carefully observe them, are very fond of show and ostentation. They lack the maturity of taste. They do not have sober habits. We can know this by their dress. Many people even if they are given costly and decent clothes, will maketheir appearance shabby and ineffective. They will put on the shirt or thecoat, but will not button it up. The laces of their shoes will remain untied. If they use the tie they will not put the knot properly. They never botherwhether their clothes are pressed or not. As these people are with theirclothes, so they are with their habits. They behave carelessly in other matters also. They are slovenly in their dress, living, reading and other ways also. So in this way, dress reflects their character. Besides this, we find people wearing very simple dress. A white ‘kurta’,‘dhoti’, and a white cap on the head and simple ‘chappals’ are all that they dress themselves in. But their clothes are always very neat and clean. Though they do not waste much of their valuable time in dressing, yet they do not use their dress carelessly. Such people show that they are thefollowers of the principle, â€Å"Simple living and high thinking†. They do notbelieve in ostentation. Mostly such people are intellectual. Broadly speaking, the dress of a man helps us to know his character. But atthe same time it may also be added that the dress should not be regarded as the sole index to the character of a man. Many saints and Sadhuscompletely neglect their dress. But it does not mean that they are very low either in their mental or emotional standard. On the contrary, they raise themselves so high from the level of such worldly considerations that dress becomes quite meaningless to them. In the present age, Mahatma Gandhiused to wear only a loin cloth. But he was the man before whom the entire world bowed its head. So in judging the character of a man dress can kelp us only to a certain extent. It can never be the sole guide. We should alsotake other factors into consideration in judging a man.

Osmosis Lab Report

Osmosis Rates in Artificial Cells Daniel George Department of Biology Grand Valley State University 1 Campus Drive Allendale, MI 49401 [email  protected] gvsu. edu Abstract The lab for this paper was conducted for the topic of osmosis, the movement of water from high to low concentration. Five artificial cells were created, each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic, hypotonic, or isotonic solutions for a period of 90 min. Over time, the rate of osmosis was measured by calculating the weight of each artificial cell on given intervals (every 10 minutes).The resulting weights were recorded and the data was graphed. We then could draw conclusions on the lab. Introduction Diffusion and Osmosis are two concepts that go hand in hand with each other. Diffusion is simply described as the movement of a substance from a region of high concentration to a region of low concentration. In another words, the substance will move down its concentration gradient which is â€Å"the region along which the density of a chemical substance increases or decreases† (Campbell Biology pg. 132). If you understand the concept of diffusion then osmosis is a very simple process.It can be defined as the diffusion of water across a permeable membrane. Osmosis can be cellular or artificial, so even though we are creating artificial cells in this lab, it is still considered to be osmosis. During osmosis, a solvent is trying to get through a selectively permeable membrane to make the concentration of that solvent the same on both sides of the membrane. The rate of osmosis depends on the type of environment the cell is in. There are three different environments that a cell can find itself in, a hypertonic environment, a hypotonic environment, or an isotonic environment.The environment a cell is in will determine its tonicity which is â€Å"the ability of a surrounding solution to cause a cell to gain or lose weight † (Campbell Biology pg. 133). â€Å"In a hypertonic solution, the cell will lose water, shrivel up, and most likely die† (Campbell Biology pg. 133). The reason this happens is because there is a higher concentration of water in the cell then there is in the environment the cell is in. Like I said before, water travels down its concentration gradient from high concentration to low concentration.So the water inside the cell will cross the membrane and enter into the solution outside the cell and it will continue to do this until the concentration inside the cell membrane and outside the cell membrane are equal. The opposite of this would be if the cell was in a solution that is hypotonic to the cell. In a hypotonic solution, â€Å"water would enter the cell faster than it leaves and the cell will swell up and lyse (burst)† (Campbell Biology pg. 134). This will also cause the cell to die. Both a hypertonic and hypotonic solution are very harmful to cell and in most cases will cause the death of the cell.A solution that a cell wants to be in is an isotonic solution. If the concentration of water in the cell and in the surrounding environment is equal, there will be no net movement of water across the membrane and therefore the cell will not shrivel up or swell up. ). An experiment has been conducted to find out whether or not osmosis is occurring by using artificial cells made of dialysis tubing. To test this hypothesis the experiment will show the change in weight of each artificial cell across a 90 minute time span.The experiment will also show which type of environment (as previously stated) each cell is placed in and taken out of to be weighed. Materials and Methods This experiment will look at the effects of various sucrose concentrations on the rate of osmosis in artificial cells made up of dialysis tubing. To begin the experiment one strip of dialysis tubing will be filled with 10mL of tap water, the second will be filed with 10mL of 20% sucrose, the third with 10mL of 40% sucrose, the fourth with 10mL of 60% sucrose, and the fifth bag will be filled with 10mL of tap water also.The dialysis tubing will be clamped at one end in order to fill it and then clamped at the other end to seal the filled bag. If the bag is not soft and floppy, the experiment will not work. Blot a bag with a paper towel to absorb the moisture and weigh it, if this blotting process is not done it could interfere with the weight readings creating inaccurate information. After the bags of the solutions are prepared, they will be placed into five different beakers with different solutions. Beakers 1-4 will be filled with tap water and the fifth beaker is filled with 40% sucrose and water.Fill each beaker with just enough water or solution so that the bag is covered and place the bags in the beakers simultaneously and record each time. Every 10 min the bags are to be taken out, blotted, and weighed again before returning them back into their resp ective beaker for another 10 min. The process is repeated until you have reached 90 min. The weights should be recorded in grams (g). Results Table 1 shows the contents of the bags and the content of the concentration it was submersed in. Bags 2-4 each contain a solution of both sucrose and water. These bags were each put into beakers containing hypertonic solution.These bags gained weight over time because the water moved from its high concentration inside the beaker to the low concentration inside the membrane of the artificial cell, the membrane being the bags that consisted of dialysis tubing. The water will continue to move through the pores of the dialysis tubing into the concentration of water is the same in the beaker as well as inside the artificial cell. Bag 1, consisting of water, was also put into a breaker containing water. The weight of this bag remains the same because it was placed in an isotonic solution, where the concentration of water was the same.Because of this , osmosis does not occur. The last bag (bag 5) contained only water whereas the beaker it was immersed in was a solution of 40% sucrose. The solution is a hypertonic solution because the concentration of water was higher inside the artificial cell then outside the cell membrane, inside the beaker. Because of this, the weight of bag 5 decreased as time went on because water was constantly leaving the bag through the pores of the dialysis tubing in an attempt to make the concentration of water equal inside and outside of the bag.As you can see from the results plotted in Graph 1, the bags that were put into a hypotonic solution gained weight over time, whereas the bag that was put into a hypertonic solution lost weight over time. Conclusion/ Discussion As you look over the results of this experiment it is clear that indeed osmosis does occur in an artificial cell with a permeable membrane made of dialysis tubing. As the data shows, the artificial cells that were placed in hypotonic so lutions had a gain in weight, the artificial cell that was placed in a hypertonic solution lost weight, and the cell placed in an isotonic solution stayed the same.The amount of weight gained or lost depends on how concentrated the solutions are, and this did not show in our results (Graph 1). †The rate of diffusion or osmosis is dependent on such factors as temperature, partial size, and the concentration gradient† (General Biology I Laboratory experiments and exercises pg. 3-1). The cell containing 60% sucrose should have ended up being heavier than the cells containing 20% and 40% sucrose, but an error must have occurred during our lab that changed the data that was collected.All in all, the results still prove our hypothesis that osmosis does occur in artificial cells. This means that when an artificial cell is placed in a hypotonic solution, it will gain weight. If an artificial cell is placed in a hypertonic solution it will lose weight, and if it is placed in an i sotonic solution it will stay the same. There are many reasons why our data could have been misleading, weather it was a small hole in one of the dialysis bags, or a faulty scale, or the inability to plot the bags dry before weighing.To better this experiment I believe you should have a scale for each of the bags so that you can weigh the bags and get them back into their respective beaker of solution as quickly as possible. Also, I believe a more successful way of drying each bag before weighing needs to be introduced but the excess water on the outside of the bags could have defiantly thrown off the data.

Diffusion is simply described as the movement of a substance from a region of high concentration to a region of low concentration. In another words, the substance will move down its concentration gradient which is â€Å"the region along which the density of a chemical substance increases or decreases† (Campbell Biology pg. 132). If you understand the concept of diffusion then osmosis is a very simple process.It can be defined as the diffusion of water across a permeable membrane. Osmosis can be cellular or artificial, so even though we are creating artificial cells in this lab, it is still considered to be osmosis. During osmosis, a solvent is trying to get through a selectively permeable membrane to make the concentration of that solvent the same on both sides of the membrane. The rate of osmosis depends on the type of environment the cell is in. There are three different environments that a cell can find itself in, a hypertonic environment, a hypotonic environment, or an isotonic environment.The environment a cell is in will determine its tonicity which is â€Å"the ability of a surrounding solution to cause a cell to gain or lose weight † (Campbell Biology pg. 133). â€Å"In a hypertonic solution, the cell will lose water, shrivel up, and most likely die† (Campbell Biology pg. 133). The reason this happens is because there is a higher concentration of water in the cell then there is in the environment the cell is in. Like I said before, water travels down its concentration gradient from high concentration to low concentration.So the water inside the cell will cross the membrane and enter into the solution outside the cell and it will continue to do this until the concentration inside the cell membrane and outside the cell membrane are equal. The opposite of this would be if the cell was in a solution that is hypotonic to the cell. In a hypotonic solution, â€Å"water would enter the cell faster than it leaves and the cell will swell up and lyse (burst)† (Campbell Biology pg. 134). This will also cause the cell to die. Both a hypertonic and hypotonic solution are very harmful to cell and in most cases will cause the death of the cell.A solution that a cell wants to be in is an isotonic solution. If the concentration of water in the cell and in the surrounding environment is equal, there will be no net movement of water across the membrane and therefore the cell will not shrivel up or swell up. ). An experiment has been conducted to find out whether or not osmosis is occurring by using artificial cells made of dialysis tubing. To test this hypothesis the experiment will show the change in weight of each artificial cell across a 90 minute time span.The experiment will also show which type of environment (as previously stated) each cell is placed in and taken out of to be weighed. Materials and Methods This experiment will look at the effects of various sucrose concentrations on the rate of osmosis in artificial cells made up of dialysis tubing. To begin the experiment one strip of dialysis tubing will be filled with 10mL of tap water, the second will be filed with 10mL of 20% sucrose, the third with 10mL of 40% sucrose, the fourth with 10mL of 60% sucrose, and the fifth bag will be filled with 10mL of tap water also.The dialysis tubing will be clamped at one end in order to fill it and then clamped at the other end to seal the filled bag. If the bag is not soft and floppy, the experiment will not work. Blot a bag with a paper towel to absorb the moisture and weigh it, if this blotting process is not done it could interfere with the weight readings creating inaccurate information. After the bags of the solutions are prepared, they will be placed into five different beakers with different solutions. Beakers 1-4 will be filled with tap water and the fifth beaker is filled with 40% sucrose and water.Fill each beaker with just enough water or solution so that the bag is covered and place the bags in the beakers simultaneously and record each time. Every 10 min the bags are to be taken out, blotted, and weighed again before returning them back into their resp ective beaker for another 10 min. The process is repeated until you have reached 90 min. The weights should be recorded in grams (g). Results Table 1 shows the contents of the bags and the content of the concentration it was submersed in. Bags 2-4 each contain a solution of both sucrose and water. These bags were each put into beakers containing hypertonic solution.These bags gained weight over time because the water moved from its high concentration inside the beaker to the low concentration inside the membrane of the artificial cell, the membrane being the bags that consisted of dialysis tubing. The water will continue to move through the pores of the dialysis tubing into the concentration of water is the same in the beaker as well as inside the artificial cell. Bag 1, consisting of water, was also put into a breaker containing water. The weight of this bag remains the same because it was placed in an isotonic solution, where the concentration of water was the same.Because of this , osmosis does not occur. The last bag (bag 5) contained only water whereas the beaker it was immersed in was a solution of 40% sucrose. The solution is a hypertonic solution because the concentration of water was higher inside the artificial cell then outside the cell membrane, inside the beaker. Because of this, the weight of bag 5 decreased as time went on because water was constantly leaving the bag through the pores of the dialysis tubing in an attempt to make the concentration of water equal inside and outside of the bag.As you can see from the results plotted in Graph 1, the bags that were put into a hypotonic solution gained weight over time, whereas the bag that was put into a hypertonic solution lost weight over time. Conclusion/ Discussion As you look over the results of this experiment it is clear that indeed osmosis does occur in an artificial cell with a permeable membrane made of dialysis tubing. As the data shows, the artificial cells that were placed in hypotonic so lutions had a gain in weight, the artificial cell that was placed in a hypertonic solution lost weight, and the cell placed in an isotonic solution stayed the same.The amount of weight gained or lost depends on how concentrated the solutions are, and this did not show in our results (Graph 1). †The rate of diffusion or osmosis is dependent on such factors as temperature, partial size, and the concentration gradient† (General Biology I Laboratory experiments and exercises pg. 3-1). The cell containing 60% sucrose should have ended up being heavier than the cells containing 20% and 40% sucrose, but an error must have occurred during our lab that changed the data that was collected.All in all, the results still prove our hypothesis that osmosis does occur in artificial cells. This means that when an artificial cell is placed in a hypotonic solution, it will gain weight. If an artificial cell is placed in a hypertonic solution it will lose weight, and if it is placed in an i sotonic solution it will stay the same. There are many reasons why our data could have been misleading, weather it was a small hole in one of the dialysis bags, or a faulty scale, or the inability to plot the bags dry before weighing.To better this experiment I believe you should have a scale for each of the bags so that you can weigh the bags and get them back into their respective beaker of solution as quickly as possible. Also, I believe a more successful way of drying each bag before weighing needs to be introduced but the excess water on the outside of the bags could have defiantly thrown off the data.

Cover Letter Example

A key part of almost any job application is a cover letter. Sometimes, that becomes even more important than your resume itself, as the cover letter shows the human behind the paper. It allows you to shine through your list of certifications and experiences and show off your soft skills and enthusiasm and convince the hiring manager you are the best match for the position. At the end of this article, you will find an example of a cover letter written in response to an online advertisement. However, before you jump straight to it, it may be a good idea to read through a typical structure of a cover letter, some writing and preparation tips, and useful key phrases. After all, you are representing yourself and your strong attributes, not someone elses online template. Structure of a Cover Letter 3-5 Paragraphs Cover letters usually run between three and five paragraphs. Note, however, that unless specifically outlined in the job posting, there is no prescribed length for this type of writing. A good thing to keep in mind is that hiring managers often only spend a brief time reviewing each application. Keeping it short and/or making it stand out in any other way (interesting and unusual words, descriptions, and/or accomplishments) could benefit you.
