You correctly answered: d. All of the energy from metabolism is ultimately stored in the chemical bonds of ATP.
In this task I will be examining how the different body systems use energy and why the body needs energy. I will also be analysing cellular respiration which is the process in which energy is made, along with the by-products and anabolism and catabolism. Later on in this task I will be analysing how ATP is used in muscle action, protein production and how we as mammals use the energy released as heat.
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?
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)
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.
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.
Due to cold conditions of spending nearly 30 hours at sea, Hypothermia was developed. The body was losing heat faster than it was gaining it and prolonged exposure to the cold conditions, led to the body temperature dropping below 35 degrees, lower than the healthy temperature of 37 degrees. In response, organs slow down, starting to fail. If temperature keeps decreasing organs will shut down leading to heart failure or death.
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 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.
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.
First, the reading passage sustains the idea of endothermic dinosaurs on the fossils discovered in Polar Regions, meaning that only this type of animals could survived in such low temperatures. On the contrary, the lecture refutes this idea by arguing that the area where the fossils were discovered was warmer back in those days when dinosaurs were alive. Moreover, as many reptiles today that live in areas with cold winters, the dinosaurs could migrate or hibernate escaping
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
Animals are separated into different classes to make them easier to understand. Mammals are warm-blooded organisms. Humans and many other animals are mammals. Reptiles are cold-blooded animals that are born on land and have scaly skin. Amphibians live in water and on land. Birds have feathers and are born from hard-shelled eggs. Fish live in water and have scales. One type of animal can have many different
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
The body temperature of most domestic animals is considerably higher than the environmental temperature to which they are exposed most of the time. They maintain their body temperatures by balancing internal heat production and heat loss to the environment. The hypothalmus gland acts as a body thermostat by stimulating mechanisms to counteract either high or low ambient temperatures (FAO, 1986). For example, increased conversion of feed to-heat energy is used to counteract low ambient temperatures, while for example increased respiration (rate and volume) and blood circulation in the skin counteracts high ambient temperatures. Varying temperature also results in changed behavior . Most animals reduce their level of activity in a hot environment and, for example, pigs lie clustered in a heap at low temperatures, while they lie
