A fish will adjust to lower water temperatures by:
A) increasing the speed of its action potentials.
B) increasing the amplitude of its action potentials.
C) recruiting different muscle fibers.
D) increasing its basal metabolic rate.

Question

Quizplus · Accepted Answer

When water temperatures drop, a fish will adjust by recruiting different muscle fibers to maintain its movement and activity level. This allows for the fish to continue swimming and feeding, even in cooler waters. The other options are unlikely, as increasing the speed or amplitude of action potentials may not be useful in response to lower temperatures, and increasing metabolic rate may require more energy than is necessary in cooler temperatures.
