Question

how does the skeletal system help the muscular system?
a by bringing oxygen into the body
b by moving blood through the body
c by protecting the body from disease
d by providing a frame where tissue can attach

Explanation:

The skeletal system provides a framework for the body. Muscles attach to bones. When muscles contract, they pull on the bones (which are part of the skeletal system) to cause movement. Option D directly relates to the skeletal system providing a structure (frame) for muscle (tissue) attachment, which is essential for the muscular - skeletal interaction in movement.

Answer:

D. by providing a frame where tissue can attach
