3. What is the function of brown fat? a. larval nutrition in fish that have direct development b. to generate heat by shivering thermogenesis c. special insulation for cold adapted mammals d. to generate heat by non shivering thermogenesis 4. In the figure on the right, which of the organisms is a poikilotherm? Rabbit 40 Cat Bettongia a. rabbit b. cat c. platypus d. gopher snake Platypus. 30 Ec hid Alligator Gopher Snake Cyclodus 10- 10 20 30 40 Ambient Temperature ( °C )Explanation / Answer
3) Brown adipose tissue is found in almost all mammals which help in the thermoregulation by non-shivvering thermogenisis. Through uncouplres on the mitochondria the H+ flow back across along the gradient without producing ATP,and the energy s released as heat.(d)
4)(d) Poikalotherms are animals that cannot regulate the body temperature except by behavioral means. the body temperature of poikalotherms change as the environmental temperature changes. From the graphs we can see cyclodus,gopher snake and alligater changes the body temperature as the environmental temperature changes. for others temperature remain more or less constant. But in option only gopher snake is included.
