Question

Endotherms or warm blooded animals maintain a constant temperature by

• A. Insulating coat
• B. Changing cutaneous circulation
• C. Both A and B
• D. Disposing off extra energy as heat

Answer 1

The correct option is C Both A and B

• Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature.
• Animals have body structures and physiological responses that control how much heat they exchange with the environment:
1. Circulatory mechanisms, such as altering blood flow patterns
2. Insulation, such as fur, fat, or feathers
3. Evaporative mechanisms, such as panting and sweating. Hence, Endotherms or warm-blooded animals maintain a constant temperature by Insulating coat
Changing cutaneous circulation .
So, the correct answer is 'Both A and B'.
