Question

Which of the following is not an important adaptation of animals to cold climate?

• A. Thin layer of body fat
• B. Aestivation
• C. Increased tendency to shiver
• D. Reduced surface area to volume ratio

Answer 1

The correct option is B Aestivation

The animals living in cold climate have various physiological adaptations like:

1) A thick layer of body fat called as Blubber to avoid loss of heat from body tissue.

2) Hibernation is a property of suspended metabolism in these organisms to surpass cold conditions.similar mechanism called aestivation exists in desert animals to survive in arid and hot conditions.

3) Increased tendency to shiver causes an increase in body temperature because of exercise thus help to withstand low temperatures.

4) The reduced surface area to volume ratio to prevent heat loss from the body surface. So, the correct answer is 'Aestivation'.
