Final answer:
Biological adaptations are already in an organism's genetic makeup, while behavioral adaptations can be rapidly changed.
Step-by-step explanation:
Behavioral adaptations can be rapidly changed yet biological adaptations do not need to be "relearned", they are already in your genetic makeup. Biological adaptations are traits or behaviors that aid in an organism's survival in its present environment and are already encoded in an organism's genetics. They do not need to be relearned because they are heritable and passed down from generation to generation through natural selection.
On the other hand, behavioral adaptations can be rapidly changed as they are learned responses to environmental stimuli. These behaviors are not encoded in an organism's genetic makeup and can be modified or acquired through experiences and interactions with the environment.
