In a resting, homeothermic endotherm, the thermoneutralzone is ____
|
|
the range of ambient temperatures where the basal metabolic rate is minimal
|
|
|
the range of body temperatures where the basal metabolic rate is minimal
|
|
|
the range of ambient temperatures where the basal metabolic rate is maximum
|
|
|
the range of body temperatures where the basal metabolic rate is maximum
|
Explanation:
Detailed explanation-1: -According to the American Meteorological Society, the thermoneutral zone is defined as “the range of ambient temperature in which normal metabolism provides enough heat to maintain an essentially constant body temperature in homeothermic animals”.
Detailed explanation-2: -Data derived from the few human studies indicate that the generally assumed human thermoneutral range lies between approximately 28 °C and 32 °C (Hardy and DuBois, 1937, Hardy and DuBois, 1938).
Detailed explanation-3: -In endotherms, the thermoneutral zone is the range of environmental temperatures over which the animal is able to thermoregulate without changing metabolic rate.
