Explanation / Answer

1) The given statement is true.

The four behavioural characteristics of skeletal muscle tissue include:

Irritability.

Extensibility.

Elasticity.

Contractility.

2) The given statement is true.

Muscle contractions produce heat approx. 70% of body heat. It is produced by energy generated in skeletal muscle tissue.

3) The given statement is false.

The fixator in a movement is the muscle. They provide an essential support to assist to hold the rest of the body.

4) The given statement is true.

A muscle with several central tendons toward which the muscle fibers converge known as multipennate muscle. Deltoid muscle is an example of multipennate muscle.
