Many species of small mammals,especially those that hibernate,increase heat production by
A)growing denser fur during winter.

C)panting.
D)sweating.

Question

Quizplus · Accepted Answer

Small mammals that hibernate increase their heat production by burning highly vascular brown fat, which generates heat through a process called non-shivering thermogenesis. This allows the animal to maintain a stable body temperature during prolonged periods of hibernation when their metabolic rate decreases significantly. Growing denser fur, panting, and sweating are not efficient mechanisms for increasing heat production in hibernating animals.
