Question

Why can migration be considered a form of phenotypic plasticity?

a-Animals that migrate tend to do so in response to environmental changes.
b-Animals that migrate undergo physical changes before migration.
c-Animals migrate in response to internal stimuli such as a change in blood chemistry.
d-Animals only migrate when forced to do so by shortages of food or water.

Answer 1

Migration is an evolved, adapted response to variation in resource availability. Animals that migrate tend to do so in response to environmental changes, such as changes in food availability or temperature. Therefore, migration can be considered a form of phenotypic plasticity.

Step-by-step explanation:

Migration is the long-range seasonal movement of animals. It is an evolved, adapted response to variation in resource availability. Animals that migrate tend to do so in response to environmental changes, such as changes in food availability or temperature. Therefore, migration can be considered a form of phenotypic plasticity because the decision to migrate and the timing and direction of migration are influenced by the organism's response to external stimuli and changes in the environment.
