Question

2. How do muscles work in pairs?

a. The pair relaxes and contracts at the same time during the movement.
b. One muscle relaxes to pull the bone while the other contracts.
c. One muscle contracts to pull the bone while the other relaxes.

Answer 1

Muscles work in pairs by contracting and relaxing in an antagonistic manner to move bones in the body.

Step-by-step explanation:

Muscles work in pairs to provide the movement of bones in the body. The pairs of muscles work in an antagonistic manner, meaning that while one muscle contracts, the other relaxes. This allows for the coordinated movement of the bones. For example, when you bend your arm, the biceps muscle contracts while the triceps muscle relaxes, and when you straighten your arm, the triceps muscle contracts while the biceps muscle relaxes.
