- Heat exchange with the environment depends on the surface area-to-volume ratio of the body. Assuming that the body shape of an animal is at least somewhat spherical, a considerable decrease in body size would _______ the surface area-to-volume ratio, and the ability to exchange heat with the environment would _______. A. increase; increase B. increase; stay about the same C. increase; decrease D. decrease; increase E. decrease; stay about the sameWhat labels would you use to describe an animal that cannot use its metabolism to generate heat but homeostatically regulates its body temperature around a specific set point using other means? Explain your reasoning.An animal living in a cold environment loses heat at a rate that is proportional to its surface area, but its metabolism generates heat in all of its cells, so the rate of heat generation is proportional to its volume. All other factors being equal (which they often are not!), which implications would follow from these facts? Choose all correct responses. Because it is smaller, a baby seal is more at risk for hypothermia (body temperature falling to too low a value) than is an adult when it is in an ocean significantly colder than its body temperature. If you take a baby outdoors on a cold day, you should dress it more warmly than you would dress yourself because it is smaller. If you take a baby outdoors on a cold day, you should dress it less warmly than you would dress yourself because it is smaller. If you take a baby outdoors on a cold day, how cold it feels to you is a good measure of how warmly you should dress that baby. Because it is smaller, a baby seal is less at…
- Although hibernators drop their body temperatures, they do manage maintain a body temperature close to or slightly above ambient temperatures in their burrows. They generate or conserve heat in all of the following ways except one. Which is the one? Non shivering thermogenesis Ruffling the pelage Eating more Calories Bouts of intense shiveringExplain Temperature Regulation (negative feedback loop)Bees and sharks show regional endothermy, what is the critical factor for generating metabolic heat in both cases? Ruffling the pelage Counter current heat exchange Muscle contraction Increased ventilation rate
- Why is heat production a good way to measure the body’s metabolic rate?Which method of heat exchange occurs during direct contact between the source and animal? a. radiation b. evaporation c. convection d. conductionPositive feedback loops are the opposite of negative feedback loops. In a positive feedback loop, any change in the original variable triggers mechanisms that actually push the variable further in the direction of the change. Imagine that body temperature was regulated in this way. Briefly explain what would happen.
- Temperature and wind combine to cause heat loss. Hypothermia occurs when the body temperature falls more than 4 degrees F below normal. Death can occur if hypothermia persists for over 3 hours. According to the chart, in which of the following temperature and wind combinations would the body temperature be the lowest and a person most at risk for developing hypothermia?Are Humans Body temperature cooling down?If yes what are its effect on Human cells and body?Which of the following occurs in the legs of goose (bird) standing on a frozen pond? Group of answer choices A. Warm blood from the body flows toward the legs of the bird. B. Cool blood from the feet flows toward the body of the bird. C.
