Which one of the following is most likely to occur in an animal during winter?
Correct answer: D. Thermogenesis
- A. Activation of sweat glands
- B. Dilation of skin blood vessels
- C. Panting
- D. Thermogenesis
Explanation
Thermogenesis is increased heat production, such as by shivering and increased metabolic activity, and helps an animal maintain body temperature in winter. The likely mistake is dilation of skin blood vessels, which increases heat loss and is more useful during overheating.
