Question

Muscle cells (select all that apply)

Select 3 correct answer(s)
Question 6 options:

Contract


Are controlled by nerves


Are controlled by skeleton


Are made up of fibers

Answer 1

The correct options are:

1. **Contract** - Muscle cells have the ability to contract, which is their primary function.
2. **Are controlled by nerves** - Muscle cells, particularly skeletal muscles, are controlled by the nervous system.
3. **Are made up of fibers** - Muscle cells are indeed made up of fibers (muscle fibers).

The option "Are controlled by skeleton" is not correct in the context of muscle cells as the skeleton itself does not control muscle cells; rather, muscle cells attach to and move the skeleton.

So, the correct answers are: **Contract, Are controlled by nerves, Are made up of fibers.**
