3. The phenomenon due to which animal sweat to reduce temperature and change electrolyte concentration is called:
[A] Homeorhesis
[B] Homeostasis
[C] Apoptosis
[D] Necrobiosis
Show Answer
Correct Answer: B [ Homeostasis]
Notes:
The phenomenon that causes animals to sweat to reduce temperature and change electrolyte concentration is homeostasis. When core body temperature increases, sweat glands respond by cooling the skin. Blood vessels also dilate, which allows the body to release more heat. Sweating is a rare ability in the animal kingdom. For example, rats don’t sweat when their core body temperature rises to 41°C. However, they do sweat in response to pilocarpine and other cholinergic agonists.
