SCRIPT FULL SOLUTION QUESTIONS AND
ANSWERS UPDATED VERIFIED GRADED A+
⩥ What role does glycerol play in some insects and frogs? Answer: It
acts as an antifreeze to prevent freezing.
⩥ What is acclimation? Answer: Gradual adjustment to environmental
change.
⩥ What is an isoenzyme? Answer: A different enzyme that works better
at a different temperature.
⩥ How do ectotherms regulate their temperature behaviorally? Answer:
By seeking the right microclimate.
⩥ What is shivering thermogenesis? Answer: Rapid muscle contraction
to generate heat from ATP.
⩥ What is nonshivering thermogenesis? Answer: Heat production
mainly in brown adipose tissue, not producing ATP.
, ⩥ What is conduction in heat exchange? Answer: Heat transfer due to
contact between bodies or structures.
⩥ What is convection in heat exchange? Answer: Heat carried away by
moving air or water.
⩥ What is radiation in terms of heat exchange? Answer: Heat emitted as
infrared radiation from an animal.
⩥ What is vaporization in heat loss? Answer: Heat loss through water
loss, dependent on humidity.
⩥ What is homeothermy? Answer: The ability of animals to maintain a
stable internal body temperature.
⩥ What is the advantage of homeothermy? Answer: Allows activity in a
broader range of temperatures.
⩥ What is the disadvantage of homeothermy? Answer: Requires more
energy and food compared to ectotherms.
⩥ What is hibernation? Answer: An extreme form of torpor where body
temperature drops drastically.
