1. Explain the differences among structural (physical), physiological, and behavioural adaptations. Give an example of each.

The difference is how and where the adaptation takes place. A behavioral adaptation is a change in behavior. A structural adaptation is a change in a species' form. A physiological adaptation is a change in a species metabolism.

Examples:

When baboons on certain Indonesian islands discovered a variety of sweet potato growing in sandy soil, they learned to wash the root in water to remove the sand. That was a behavioral adaptation; they had not previously washed their foods.

A certain species of bird ate insect larvae that lived in trees. The species evolved a long, narrow beak to more easily reach its foods. That was a structural adaptation.

A group of white-skinned European humans migrated into Africa several thousand years ago. Over the course of many generations they evolved skin as dark as the native Africans. Dark skin is a response to the intense sun. That was a physiological adaptation.

Often you will see behavioral, physiological, and structural adaptations which evolve together and complement each other, such the mating behavior, coloration, and mating compatibility of birds species.

2. No, it’s analogous though. It is analogous because both are structured different but function for the same cause. The wings don’t have the same bone structure but have the same function; flying.
