Most artic mammals are warm blooded animals‚ known as endotherms‚ and they maintain similar internal body temperatures to warm blooded animals in any other climate zone. Their body temperature

maintain homeostasis. What would happen if our thermoregulation (temperature control) used a positive feedback to maintain homeostasis? There are two feedback mechanisms our body uses to maintain homeostasis‚ they are negative feedback and positive feedback. Both feedbacks signal a response to the situation. Negative feedback however will correct the situation where positive feedback drags the process on or exaggerates the situation. If our thermoregulation used a positive feedback to maintain homeostasis

This dingo is found near the main lands with very good water source the dingo is a warm-blooded animal and it’s a carnivore that eats everything. This animal called a dingo is an endotherm which means a warm blooded animal. That survives on its body heat to keep it warm in winter. They are meat eaters‚ and try to feed mainly on this. If unavailable‚ dingoes have been known to eat reptiles‚ and any food source it can find. When food

and wellbeing. The structure of the skin is important in ensuring these functions can be performed. The skin provides a reasonably waterproof layer for the body and offers protection as a main function‚ as well as other key functions including thermoregulation and sensation. Other functions of the skin involve absorption and secretion of fluids and substances‚ and synthesis of vitamin D. This essay will outline the structure of the skin and describe in detail the skins functions while also highlighting

Can tegu lizards maintain an elevated body temperature during their reproductive season? Experiment: Dr. Glenn Tattersall and a team of researchers in Rio Claro‚ Brazil studied changes in the heart rate and body temperature of tegu lizards (Salvator merianae)‚ by implanting lizards bred in captivity with specialized electronic chips. One group of lizard lived in an entirely outdoor environment for one year. Three other groups that were subjected to alternating indoor and outdoor environments over

The goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus
