- Compared to animals that are smaller, animals that are larger become cold more easily because they have a greater volume of tissue to keep warm have an easier time retaining heat produced by their metabolism are better adapted to and more likely to rely on cutaneous respiration because they have more skinarrow_forwardHeat 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 samearrow_forwardWhich of the following statements is incorrect? a) Acclimatization involves genetic change. b) Adaptations emerge over many, many generations. c) Tanning is an example of acclimatization. d) Adaptation is inherited, acclimatization is notarrow_forward

How do camels lose heat during the night without the use of water?arrow_forwardWhich method of heat exchange occurs during direct contact between the source and animal? a. radiation b. evaporation c. convection d. conductionarrow_forwardWhat 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.arrow_forward
- After a long, hot run together, your friend tells you that you should dunk your head into a cooler of water to lower your body temperature more rapidly, rather than sitting and waiting to cool down. What do you think? Form a hypothesis, about how the ice-cold water might affect the rate at which your body temperature returns to normal. How could you test your hypothesis? Explain your answer.arrow_forwardYou are studying a large tropical reptile that has a high and relatively stable body temperature. How do you determine whether this animal is an endotherm or an ectotherm? (A) You know from its high and stable body temperature that it must be an endotherm. (B) You subject this reptile to various temperatures in the lab and find that its body temperature and metabolic rate change with the ambient temperature. You conclude that it is an ectotherm. (C) You note that its environment has a high and stable temperature. Because its body temperature matches the environmental temperature, you conclude that it is an ectotherm. (D) You measure the metabolic rate of the reptile, and because it is higher than that of a related species that lives in temperate forests, you conclude that this reptile is an endotherm and its relative is an ectotherm.arrow_forwardInsects, birds, and bats can fly. Which of the following is a derived characteristic unique to birds and bats? A. light body weight B. modified limbs for flight C. high metabolic rate D. large surface of wingarrow_forward
