Question

Which of the following animals uses the largest percentage of its energy budget for homeostatic regulation?
a. marine jelly (an invertebrate)
b. snake in a temperate forest
c. desert insect
d. desert bird

Accepted Answer

Welcome back Now we'll look at the question which of the following characteristics. Is not included in an animal's adaptation to homo static regulation in the arctic region. So obviously we're thinking about very cold environment. And so we need adaptations that allow the animal's body to maintain a temperature warmer than the outside environment. So let's look through our choices here. Choice A. Says storage of fat. Well extra fat storage provides insulation to keep heat in front and from losing heat. So that would be an adaptation to arctic. So therefore we can eliminate that as a choice. Since we are looking for things that are not included. Choice B. Is development of thick fur. Again, another adaptation that traps heat, keeps it from leaving the animal's body so we can eliminate choice B. Choice C. Is hibernation. Hibernation allows the animal to go into hibernation, its metabolic rate to slow down. So it doesn't need to be out searching for food out in the environment during the harshest and coldest part of the winter. So that would be an adaptation to help it maintain its homeostasis. So in cold weather so we can eliminate choice C. Well we just have choice D. Left choice D. Is sweating. Um But sweating is obviously an adaptation to help an animal lose heat and to maintain homeostasis in hot conditions. So D sweating is not an adaptation to cold weather. See you at the next video
