The sarcomere<span> </span><span>is the basic unit of a </span><span>striated muscle and the force of a muscle is directly related to the extension that the sarcomere is under. When a sarcomere is extended from 1.5 micrometres to about 3 micrometres, the muscles' force is great and max at about 2/2.5 micrometres. When the muscle is fully extended and, therefore, the sarcomere is extended over than 3 micrometres, the muscle force decreases exponentially.</span>
It is A) a polymer.
Because Polymer is a large molecule and made of smaller molucules and they are called monomers
