b) Push
c) Contract
d) Expand

Answer 1

Body movements happen when muscles pull across joints, moving one bone toward another.

Step-by-step explanation:

The correct answer is a) Pull. Body movements happen when muscles pull across joints, moving one bone toward another. Muscles are attached to both bones on either side of the joint by tendons, which are tough bands of connective tissue that connect muscles to bones. When muscles contract, they get shorter and pull on bones, allowing the body to move.
