A Moth Preparing for Flight on a Cold Morning Warms

Question

A moth preparing for flight on a cold morning warms its flight muscles via
A) acclimatization.
B) torpor.
C) evaporative cooling.
D) nonshivering thermogenesis.
E) shivering thermogenesis.

Accepted Answer

Shivering thermogenesis is the process by which the moth warms its flight muscles by rapidly contracting and relaxing them, generating heat in the process. This allows the moth to raise its body temperature to a level at which it can fly, even on a cold morning.
