Honeybees must maintain specific temperatures to thrive. On hot days, the hive can quickly
overheat, so some bees will stand near the entrance and fan their wings to provide cool air
currents into the hive. In winter, honeybees cluster together in their hives and vibrate their
wings in a form of shivering to generate heat and maintain the hive at a constant temperature.

a. homeostasis.
b. evolution.
c. competition.
