What is the probable metabolic response of a mammal exposed to an environmental temperature that begins at the lower limit of the thermoneutral zone and increases 3°-5°C above that point,staying within the thermoneutral zone?
A) Increased metabolic rate
B) Decreased metabolic rate
C) No change in metabolic rate
D) Death
E) Both b and d

Quizplus · Accepted Answer

The thermoneutral zone is the temperature range in which an animal can maintain a stable body temperature without having to use extra energy to regulate it. Therefore, if the environmental temperature stays within the thermoneutral zone, there is no need for the mammal to increase or decrease its metabolic rate to maintain its body temperature. Thus, there will be no change in metabolic rate.
