Motor units that control skeletal muscles involved with fine motor movements (eye muscles or 35) the hands) have muscle fibers than motor units that control more gross movements (gastrocnemius muscle of the lower leg).

Options are not provided. The complete question is:

Motor units that control skeletal muscles involved with fine motor movements (eye muscles or 35) the hands) have muscle fibers than motor units that control more gross movements (gastrocnemius muscle of the lower leg).

A) fewer

B) more

C) the same number of

A) fewer

Explanation:

The number of muscle fibres in each unit may differ within a single muscle and even more from muscle to muscle. Muscles operating on the largest body masses contain more muscle fibres in their motor unit, while smaller muscles have less muscle fibres in each motor unit. For example, Thigh muscles may have a thousand fibres in each unit, whereas extraocular muscles can have ten fibres in each unit.

Muscles that have more motor units are able to operate more force output.

Hence, the correct option is A.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
