Question

The purpose of warm-bloodedness in mammals is:

• A. Maximum evaporation from body surface
• B. Increased metabolism
• C. Keep body temperature constant in spite of change in climate temperature
• D. Continuous production of energy for physiology

Answer 1

Answer: (C)

Homeothermy or warm-bloodedness is the ability to maintain a constant internal temperature (about ${37}^0$ C). This helps mammals to regulate their metabolism and keep it constant at climatic change.

So, option C is correct.
