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). 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). 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. 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. The results of this experiment are shown in the compiled student data in Table 1 below.
After results, it was concluded that isopods prefer normal temperature conditions over warm conditions. We created these environments by adding water onto filter papers with the accounted for temperature measurements. The reason for the results could be seen in a usual isopod environment, it is usually dark, fresh, and moist, and the normal water temperature being the closest to that was the reason for their choosing. The Isopods seemed to locate the appropriate environment by the use of their antennas. For the investigation the normal water and warm water temperatures were independent variables. The observations were the control. The isopods behavior served as the dependent variables. The isopod behavior would be classified as movement in response to a cooler temperature environment taxis. All in all the hypothesis, “If the isopods are exposed to normal and warm temperatures then the normal temperature will be preferred” proved to be
More reliable data can be obtained if more techniques are used to measure metabolic rate. By measuring the heat flow from an organism to its surroundings using a calorimeter, a more accurate metabolic rate can be measured (De V. Weir, 1949). The ratio of the quantity of food an animal consumes and the amount it excretes can also indicate the metabolic rate of that animal (Paradis et al., n.d.). Determining the water flux in animals with tritium labelled water is another valid method of measuring metabolic rates (Paradis et al., n.d.).
The American Dream is starting with nothing and through hard work someone can achieve all the happiness one can handle. But if that person were to try to buy the past to regain the happiness they once had they will never succeed. A example of this is F. Scott Fitzgerald 's, The Great Gatsby. Fitzgerald criticizes the American dream in his novel, The Great Gatsby, by showing ones belief that money can buy happiness and love through the American dream and also shows the corrupting influence of wealth to the purity of that dream.
The human body is made of cells, which means that if the cells die, the human dies. Metabolism keeps the cells and thus the body alive and functioning properly and can be divided into two parts: catabolism and anabolism. Catabolism breaks down molecules in order to gain energy while anabolism synthesizes everything that the cells need.
Human institution are not perfect, so is married couples. Effective interpersonal communication is essential in resolving frequent problem that arise from every human marriage.
Communication is the chain in any relationship. Between a husband and a wife, the role of communication plays a main part in maintaining the relationship. In Sex, Lies and Conversation, Tannin says, “complaints from women about their husbands most often focused not on
The higher the temperature change is, the higher the enthalpy change will be and vice versa.
The green light at the end of Daisy Buchannan's dock signifies both hope and the difficulties Gatsby encounters while pursuing his Dream. Throughout the novel, Gatsby expresses hope in various ways, but the most evident of all is when he reaches out with his hands toward the green light. When the narrator, Nick Carraway is introduced to Gatsby in the beginning, he watches Gatsby stretch out his arms toward "...a single green light, minute and far away, that might have been the end of a dock"(Fitzgerald,25). Gatsby pointing toward the end of the dock signifies hope, but also his desire to be with Daisy. Just across from the ba...
The simple definition of the American dream is a state of happiness a person hopes to achieve by obtaining materialistic prosperity through hard work. This however has not always been the dream. In early America the dream of many was to venture west, find land, and start a family, but as time progressed the dream has transformed into a need for materialistic possessions such as a car or a large house. In F. Scott Fitzgerald’s book The Great Gatsby, Fitzgerald reveals the how corrupt the American Dream has become and how truly irrelevant money and worldly possessions are to becoming genuinely satisfied. He does this through his portrayal of Gatsby’s confused love for Daisy or the idea of Daisy, Daisy and Tom Buchanan’s marriage, and the death of Gatsby.
Although the experiment produced varying results amongst the pairs of test tubes in each of the water temperatures, the Mean calculations proves that the temperature rising will increase the amount of kinetic energy in the movement of the Phosphate and Lipids in the cell membrane as well as breaking the hydrogen bonds of the proteins in the cell membrane,
The American Dream, in the 1920’s, turned into a greedy system of obtaining wealth. Jay Gatsby, Daisy Buchanan, Nick Carraway, and Jordan Baker demonstrate that the American Dream has become corrupt through their symbolism in The Great Gatsby, by Scott Fitzgerald. The American Dream is about the pursuit of happiness, and that everyone is equal in opportunity to obtain happiness. Yes, if you want to make money and become wealthy, you can do that, given that you work hard enough. But this is where things start to get corrupt. The most important things in life are the relationships that you form with the people around you. In the 1920’s, it was all about having money and expensive possessions. Jay Gatsby had a dream of him and Daisy living the rest of their lives together, happily in love, but that dream was crushed by Tom, and he was ended by George, thus destroying the last shreds of the American Dream.
Kim Joo-Won experience strong feelings for the feisty stunt woman, even though she isn 't his type. Joo-Won tried getting Ra-Im out of his mind for Ra-Im does not own a high status life nor is even rich. Another person who thinks this way was Kim Joon Won’s mom, she hated Ra-Im. Kim Joon Won’s mom view Ra-Im the same way as her son. She even pay Ra-Im to go away from Kim Joon Won because she was not good enough for him. And Kim Joo-Won didn’t similar things like this mother did to Ra-Im, there were one scene toward the middle of the movie where he was ashamed seeing with her because she was using a rip beg, where old clothes. There, he did a makeover for her so he look like she in a higher class. Since then, Ra-Im tries her best to ignore Joo-Won because she knows Joo-Wan belongs to another higher social level compared to him. She still think that lower class should never be mix with higher class and that they don’t belong together.
Communication is important in relationships as it allows us to share our interest, concerns, support each other; organize our lives and make decisions; and it allows us to work together. Effective communication is based on the way we talk and listen, how we respond and our body language. We can all learn how to improve the way we communicate.
Enzyme activity increases as temperature increases. Inversely, enzyme activity decreases as temperature decreases. At higher temperatures molecules move faster causing them to collide more. Therefore, enzymes collide with their substrates more at higher temperatures and the opposite at lower temperatures. When the temperature gets too hot, however, the enzyme will denature meaning its shape will be changed to the point where it can no longer bind with its substrate. This experiment will show the effects of temperature on enzyme activity of an amylose enzyme.
Susan Heitler) “Communication in relationships is like a river. When thoughts and feelings flow smoothly between marriage partners it 's fun, feels good, and helps support everyone around. However, when communication flow is turbulent, it 's potentially dangerous and destructive. And when communication gets blocked, pressure builds up. Then when the words start flowing again, they tend to come out suddenly in a damaging raging flood” If you and your spouse do not communicate effectively, you are both likely to experience frustration, anger and resentment. On the other hand, couples who communicate well experience fulfilled relationships, empathy and true intimacy with their spouses. Effective communication in marriage is perhaps the single most important aspect of a successful
