Explain how your thirstrelates to the concept of homeostasis. Whichtype of feedback—positive or negative—does this illustrate?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_forwardAfter 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.

The tiger has a larger surface-area-to-volume ratio and will cool more quickly. D. The tiger can cool more quickly because of decreased metabolic rates within larger animals.arrow_forward(a)What are the stimuli in the picture?
