Exothermic Animals Research Paper

3. Convection the transfer of heat through currents of gases or liquids. (occurs passively as warmer air at the surface of the body rises away from the body and is replaced by cooler air – process is aided by wind or fans)

3. Thermal springs, such as Old Faithful in Yellowstone National Park, have temperatures above 100°C. How does adaptation make it possible for living organisms to inhabit such an extreme environment?

Metabolism is a chemical process that converts fuel from food into energy needed for the body’s activities. For example, thinking, running and jumping etc. are all an example of the bodies activities.

The purpose of this lab is to analysis goldfish an ectothermic animal affect toward different temperature ranges. The reactions toward the temperatures are taken upon the term of homeostasis, which is regulation for organisms to maintain a steady state while adapting to the conditions that are favorable for survival (Encyclopedia Britannica). In order to achieve a successful homeostasis, many animals use different methods of thermoregulation, which helps maintain the internal temperature of animals. Many methods vary whether the organisms is an endotherm or ectoderm. An endotherm, which includes mammals and birds, is a warm-blooded animal, which maintains a constant body temperature not influenced by the environment (Britannica).

Somewhat more precise descriptions can be made by using the terms poikilothermic and homoiothermic. The body temperature of poikllotherms is relatively variable, while that of homeotherms is relatively constant.

On an individual level - physiology of penguins: The ends of bird’s feather consist of tiny barbs, under normal circumstances, that interlock with each other and provide insulation to a penguin. However, when it comes in contact with oil, the hydrophobic nature of oil separates the interlockings of barbs and birds lose their insulation. This exposes birds’ skin to extreme temperature and makes them susceptible to hyperthermia which can eventually lead to death.

Introduction The ability to maintain a relatively stable core body temperature regardless of the external environment is referred to as homeothermy (Wooden and Walsberg 2002). It is an evolutionary feat that has enabled endotherms to thrive in harsh conditions past and present. In colder climates endotherms may grow fur to aid with insulation. However, there is a trade-off.

If you were wearing layers of clothing the whole year round, you'll get a heat stroke too. Your feline friend is prone to heat exhaustion as much as any furry pet in town. Most cat owners neglect to check on their fur balls during the summer because cats are generally independent compared to other pets. So, while your neighbor's pet poodle might get all the pampering in the world, your kitty could already be suffering from a cardiac arrest without your knowledge.

The author believes that dinosaurs' fossils in the polar area show they had to be endotherms in order to be able to live in that cold weather but the lecturer believes that the polar area were much warmer than today years ago and dinosaurs could have just migrate to lower latitudes during winter or just hibernate.

The purpose of this journal article was to test two different cooling methods on Murrah buffalo under heat stressed conditions. Summarizing the study, they selected 12 Murrah buffalo that had previously calved 2 or 3 before and were in early, 50-70 days, lactation during the study. The trial took place for a span of 60 days, 30 during the May-June months and the other 30 in the August-September months. 6 buffalo were placed under constantly running water showers (Group 1), while the other 6 were allowed to wallow in a water pond from 11 A.M. to 4 P.M (Group 2). They collected blood samples from both groups on 3 day intervals for both trial time periods, specifically testing for plasma thyroxine (T4), triiodothyronine (T3), cortisol, and insulin hormones. During the study the buffalo had ad lib water and access to green maze fodder. They wanted to also see how differences in humidity would impact the effectiveness of the cooling methods and how it would impact the buffalos milk and feed yields. The average temperature humidity index (THI) was 80.3% during the hot-dry season and 83.6 during the hot-humid season. The results showed that the buffalo that wallowed in the water pond had a higher average plasma T4 and insulin level compared to those under water showers in the hot-dry season. Plasma T3 levels weren’t noticeably different between Group 1 and 2. Although Plasma cortisol concentration in Group 1 were higher when compared to Group 2 (4.80 vs. 2.60 ng/ml). In the

Dogs and cats can adapt quite nicely to the temperatures that we enjoy. But reptiles are cold-blooded animals and need the sun to heat up their body temperature. This usually means a heating lamp or other device to keep their enclosure warm. With some reptiles, there may be humidity requirements as well. In short, there is a

According to the passage, dinosaurs were endotherm because they some of them lived in the polar region and only endotherm animals could live in such a cold environment. The lecturer contradicts this theory and asserts that polar regions were warmer in those days and dinosaurs also could migrate during cold periods or hibernate just like many modern reptiles.

The passage points that dinosaur fossils have been found in polar area where is very cold and merely endotherms could live there. However, the professor explains that these days Polar Regions are much colder than used to be. Therefore, this claim could not prove the author's idea.

First of all, the author contends that polar dinosaur fossils are great evidences that dinosaurs are endotherms. This is because only animals capable of maintaining a high enough body temperature will be able to move in the polar regions. The lecturer believes otherwise. He mentions that the polar regions weren’t as cold as they are now. In addition, the polar
