one muscle flexes (bends) and the other muscle extends.
one muscle does more work and the other muscle does less work.
one muscle uses more energy and the other muscle uses less energy.

Answer:

One muscle flexes while the other extends

Explanation:

Most skeletal muscles are in pairs so that one muscle flexes (bends) and the other muscle extends. Thus, the correct option for this question is B.

Muscle contraction may be defined as the process that involves the tightening, shortening, or lengthening of muscles when you perform some sort of physical activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Skeletal muscles are the muscles that typically connect to your bones and allow you to perform a wide range of movements and functions. Skeletal muscles are voluntary, meaning you control how and when they work.

These types of muscles lay the central framework for the entire body and facilitate the movement and functioning of the entire body.

Therefore, most skeletal muscles are in pairs so that one muscle flexes (bends) and the other muscle extends. Thus, the correct option for this question is B.
