|
|
metabolic rate rises to prevent overheating
|
|
|
metabolic rate decreases to prevent overheating
|
|
|
metabolic rate rises to prevent cooling
|
|
|
metabolic rate increases to prevent cooling
|
Explanation:
Detailed explanation-1: -The thermoneutral zone describes a range of temperatures of the immediate environment in which a standard healthy adult can maintain normal body temperature without needing to use energy above and beyond normal basal metabolic rate.
Detailed explanation-2: -Metabolism increases above the upper critical temperature (UCT) from active loss of heat through panting and evaporative cooling, as well as the direct effects of higher temperatures on cellular functions.
