Question

Select the correct statement describing feedback control in animals.

Answer 1

Answer: A. An animal may be a regulator for one environmental variable but a conformer for another.

Explanation: 'An animal may be a regulator for one environmental variable but a conformer for another' is the correct statement when describing feedback control in animals. Animals are constantly adjusting the internal and external behavior or processes in other to attain a steady state or equilibrium through a process called homeostasis. The adjustments are required to maintain a set range in body glucose, calcium, temperature and so on to aid efficient function of the body system.

For instance temperature, cold-blooded animals or ectotherms depends on external heat sources, therefore conform to the environmental temperature While endotherms possess the ability to maintain a constant steady temperature independent of the environment.
