Which type of muscle is Type A? Cite the evidence from the chart to support your answer.

Type A are skeletal muscles, because skeletal muscles are the only voluntary type.
Type A are skeletal muscles, because skeletal muscles are the only type with striations.
Type A are smooth muscles, because smooth muscles tire quickly.
Type A are smooth muscles, because smooth muscles do not have striations.

Answer 1

A

Step-by-step explanation:

I did the test.

Answer 2

Answer: A option

Type A are skeletal muscles, because skeletal muscles are the only voluntary type.

Step-by-step explanation:

There are three types of Muscles:

1. Skeletal Muscles
2. Smooth Muscles
3. Cardiac Muscles

From the given table we have to identify which type of muscles are Type A. From the table we can list the following properties of Type A muscles:

• Are voluntary
• Have striations
• Tires Quickly

These three characteristics belong to Skeletal muscles only. Therefore, option C and D cannot be correct.

Option A and option B both lists the skeletal muscles. Now we have to identify which of these is correct. Option B reads that skeletal muscles are only type with striations. This is incorrect as Cardiac Muscles are also without striations.

Hence option A is the correct answer as skeletal muscles are the only muscles that are voluntary muscles.
