Explanation:

Question 9

Hermit crabs switching shells is a behavior they do to protect themselves, so it's a behavioral adaptation.

Dolphins hunting cooperatively in pods is a behavior for catching food, so it's a behavioral adaptation.

Tube feet are a physical structure of sea stars that help with grip, so it's a structural adaptation.

Answer:

a) Behavioral adaptation
