Answer 2

Answer:

Explanation:

all muscles are joined with the bones, which provide the basic support to the body structure. Generally, two skeletal muscles are joined to one bone, so that when one muscle contracts in one direction for enabling the bone to move in that specific direction; the other muscle becomes relaxed to facilitate the movement of the bone.

like we need a lower jaw and upper jaw to eat.\

if only one muscle is present the hand will go down but not come up.
