Effect Of Temp On Endo And Ectotherms (metabolism) :: essays research papers

Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996).   Ã‚  Ã‚  Ã‚  Ã‚  Metabolic rate is directly linked to the core temperature in an animal. An ectotherm, or cold blooded animal, warms its body mainly by absorbing heat from its surroundings. The amount of heat it derives from its metabolism is negligible. In contrast, endotherms derive most or all of its body heat from its own metabolism (Campbells,p899). Because ectotherms do not produce their own heat, they cannot actively ensure their ideal temperature for an ideal metabolic rate (aquacult.htp).   Ã‚  Ã‚  Ã‚  Ã‚  In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental temperature in both an ectoderm and an endotherm. I predict that for the ectotherm, the metabolic rate will increase as the outside environment temperature will increase. I also predict that the metabolic rate in the endotherm will remain relatively the same as the outside environment temperature changes. I also make the prediction that the ectotherm will have much lower metabolic rates than the endotherm.   Ã‚  Ã‚  Ã‚  Ã‚  The procedures for this experiment are those that are referred to in Duncan and Townsend, 1996 p9-7. In our experiment however, each student group chose a temperature of either 5 C, 10 C, 15 C, or 20 C. Each group selected a crayfish, and placed it in an erlenmeyer flask filled with distilled water. The flask’s O2 levels had already been measured. the flask was then placed in a water bath of the selected temperature for thirty minutes, and then the O2 levels were measured again. Each group shared their findings with the class. The metabolic rates of the mouse were conducted by the instructor and distributed. We also did not use the Winkler method to measure the O2 levels. We used a measuring device instead.   Ã‚  Ã‚  Ã‚  Ã‚  The results of this experiment are shown in the compiled student data in Table 1 below.

Critical Analysis of Edvard Munchs The Scream Essay -- Visual Arts Pa

Critical Analysis of Edvard Munch's The Scream "The Scream", sometimes known as "The Cry" was painted by Edvard Munch in 1893. Some say Munch played a role in the development of German Expressionism, though the Norwegian painter turned down two offers to join the group, and preferred not to be classified, or 'put' into a category. This painting was part of Munch's "The Frieze of Life", a series of paintings each portraying a phase of life - as defined by Munch: Birth of Love, Blossoming and Dissolution of Love, Anguish of Life, and Death. The eleven paintings - "The Kiss", "Madonna", "Ashes", "Dance of Life", "Melancholy", "Red Virginia Creeper", "The Scream", "Death in the Sick-Room", "Puberty", "Moonlight", and "The Sick Child" - are as moving today as they were a hundred years ago when the motifs were first conceived. Munch finished "The Scream" in 1893. It was a work of great personal meaning to him. The painting was like the culmination of all the tragic and harrowing events in his life. When Munch was aged only five years old, his Mother died from Tuberculosis. Nine years later, his favourite sister Sophie dies from tuberculosis also, at the age of 15. Frequent illnesses prevent him from attending Technical college in Christiania (Oslo). In 1889, he is hit with perhaps the biggest blow so far: his beloved father dies. Munch wrote: "And I live with the dead ones; my mother, my sister, my grandfather, my father- he, especially. Every memory, every little thing, they all come back to me in flocks. I can see him again as I saw him for the last time four months ago, when he told me goodbye on the bench; we were a little bit shy, we didn't want to betray the pain that this separation was causing to us. How much we loved each other in spite of everything, how much he worried at night for me, for my life - because I couldn't share his faith" Therefore, it is not surprising that the mood of the painting is so haunting. Munch painted it surrounded by morbidity. The point in the painting where we see the figures, was a road on top of a hill looking over Christiania and the harbour. On one side of the hill was a psychiatric hospital where one of his sisters had been sent, and on the other side, an abattoir. Munch described the feeling he experienced in a diary entry in his literary diary in Nice, on the 22nd January 18... ...e influenced two German expressionist groups, Die Brà ¼ke and Die Blaue Reiter. He had two offers from Die Blaue Reiter to join them, but he turned both down. Painting was for Munch a personal experience, and he did not like to share it, or put his works into any grouping. The painting itself looks quite 'slapdash', as though it was rushed. The thick streaks of oil paint give the effect of a movement blur, like the world was swirling around the figure. It is hard to distinguish between the water and the land, difficult to recognize where the hills in the background stop and the sunset begins. "The Scream" is a painting full of emotion, full of character not understood at the time of its birth. It reflects Munch's life at that time, all the Death and anxiety that makes the painting so mysterious and haunting, whilst also lively. When I look at it, I feel I can hear the scream echoing from it. The screaming figure draws the attention of the onlooker, but other aspects of the painting are just as interesting. Whilst we cannot know what was going through Munch's mind when he painted"The Scream", we can guess that the painting evokes all the pain he was feeling.

Answer:This theory suggests that early in a product’s life-cycle, all the parts and labor needed to manufacture the product will be sourced from the locale in which the product was invented. As the product is increasingly adopted and distributed in global markets, production gradually shifts away from the point of origin. In some cases, the product ultimately becomes a good that is imported into the country in which it was originally invented. For example, in the case of personal computers, during the new product stage, the computer was produced and purchased by consumers in the United States and little export trade occurred.During the maturing product stage, mass-production techniques were developed and foreign demand (in developed countries) expanded . At this point, the U. S. began to export the product to other developed countries. In the standardized product stage, production moved to developing countries, which then export the product to developed countries. Difficulty: Moderate Page: 5-6 Topic: Product cycle theory20. Briefly compare and contrast the Uppsala Internationalization Model and the Born Global Model. Under what circumstances is each model most applicable?Give examples to support your arguments. Answer: According to the Uppsala Model, companies internationalize in an incremental fashion. Typically, they start by utilizing foreign entry modes that require low levels of resource commitment and low levels of control over foreign activities (e. g. exporting). The model conceptualizes subsequent stages in the internationalization process as requiring higher levels of resource commitment and providing higher levels of control over foreign activities (e. g. wholly owned subsidiary). The experience of Toyota is consistent with the Uppsala Model.According to the Born Global Model, some companies are born global, establishing significant international operations immediately or shortly after the company is launched. These firms do not employ an incremental approach. Instead, these firms aggressively pursue internationalization due to their internal orientation or the need to move quickly due to the nature of their products or services. The experience of many internet companies is consistent with the Born Global Model. Difficulty: Moderate Page: 9-10 Topic: Process of internationalization21.Roy is the CEO of a multinational apparel company. How would he conceptualize the strategic role of his firm’s foreign operations if he possessed a ‘global mentality’? If he possessed a ‘multinational mentality’? Answer: If Roy possessed a global mentality, he would view the world as a single unit of analysis and he would centralize the management of the firm’s foreign operatio ns. Thus, he would drive the firm to create products for a world market and manufacture them on a global scale in a few highly efficient plants, often located at the corporate center.However, if Roy possessed a multinational mentality, he would regard foreign markets as a portfolio of local opportunities and manage his company as a decentralized federation. Thus, he would recognize and emphasize the differences between national markets and operating environments and modify his products, strategies and management practices on a country-by-country basis. Difficulty: Moderate Page: 11-13 Topic: Mentalities toward internationalization22. What is an MNE? Give examples to explain the difference between companies that are considered MNEs and those that are not. Answer:An MNE is a company that engages in the active management of substantial direct investment in one or more foreign countries and that considers those investments/operations as integral parts of the company, both strategically and organizationally. Thus, companies that solely rely on import-export business are not considered MNEs. They may be considered international companies but not multi-national enterprises (MNEs). Moreover, companies that passively manage an investment portfolio (as opposed to those that actively manage foreign assets) are not considered MNEs. Difficulty: Easy Page: 2 Topic: MNE definition23.Briefly compare and contrast the four mentalities toward internationalization. Answer: Companies that have an international mentality produce products for the domestic market and only subsequently sell these products overseas. They transfer innovation and knowledge from the parent company to the foreign operators. These companies view themselves essentially as domestic with some foreign appendages. Companies that have a multinational mentality modify their products, strategies, and management practices country by country. These companies view themselves as nationally sensitive and responsive, thu s the term multinational.Companies that have a global mentality create products for a world market and manufacture them on a global level in a few highly efficient plants. These companies view the world, not just individual national markets, as their unit of analysis. Companies that have a transnational mentality are responsive to country-level operations; however, they coordinate these operations to sustain competitive effectiveness and economic efficiency. These companies view themselves as an integrated network. Difficulty: Moderate Page: 11-14 Topic: Mentalities toward internationalization

Child Hunger

Ending Child Hunger in America Studies prove that children that do not have enough food to eat do not do as well in school, they are likely to be sick more often, they are less likely to graduate high school – which in turn will keep them from going to college and in turn will have a negative Impact on their economic future. If these things happen then In the future that child will have a harder time providing for their children, thus causing a cycle In the effects of hunger.For this reason, It Is our duty as a society to do everything we an to ensure that these children have the resources available to them so that they can have the tools they need to prepare themselves to be functioning members of society In adulthood. There are currently more than sixteen million children In America whose families struggle to put food on the table – that's one In five children In America. That number is astonishing. Millions of children In America are on free or reduced lunch plans at their schools; this allows them to have nutritious meal while at school.But what happens when they go home? What happens during the summer when kids are out of school for several months? Only one in seven children on free or reduced lunch plans receives summer meals. What happens to those other six children – who ensures that they have enough food to eat? The solution is simple – we need to end child hunger in America. There are many ways to do this. First, there are church programs locally that offer summer and weekend home meal plans to children that are on free and reduced lunch plans.One such church is Midtown Church in Benton, Arkansas. They're program, known as the â€Å"Backpack Ministry† helps to provide weekend meals and snacks to children throughout the community who otherwise would not have anything to eat. Secondly, these types of programs should be better advertised and more easily accessible to those who need them. Access to programs is of utmost importance when ending child hunger. Next, education is vital – the parent's of these children must learn and understand the effects that hunger can have on their children.They must be educated on good food hoicks for their children and what the best things they can give them are. They need to know where to go to get connected to the right people that can help them find access to these programs that are designed to end child hunger. Spreading awareness of child hunger can ago long way. If the public has knowledge of what the numbers look like in the world of child hunger, they would be more likely to take action. The public has a greater power than they realize – people have the power to promote change.

Set of rules to run a superlative business Essay

Set of rules to run a superlative business - Essay Example One may be the exchange of currency that is foreign exchange system, which allows the raise in amount by buying a low rate currency, and selling at time it raises its value. Bonds may also help to get spare amount as they works as lottery tickets that never go waste if not won. But paramount to earn equity in market is investing amount by buying shares of other emergent companies and selling them at the profit. There are now a day many sock reporting tools that helps the businessman to know about the stock history, and other fundamental data at the end of the day. By technical and fundamental analysis they helps to pick the stocks. Moreover, many different online sites are available for the same purpose. They help business people by showing the reports after analyzing different companies in form of equity research. The mortgage is the amount an investor earns as a profit on the property bought. That is, for instance, businesspersons bought a property in a non- establish location which in few years gets establish in a manner that property bought about 1 hundred dollars can be sold at price 100times more. Though this is the profit earned Property dealers are operating through hundreds of subsidiaries in the business market. These equity offices later converted into real estate management. Now these real estate offices have grown in size through strategic acquisitions.
