Final answer:
Muscle tissue has the ability to be elongated or stretched, known as extensibility. This allows muscles to stretch and extend to accommodate movement. The correct answer is option b.
Step-by-step explanation:
Muscle tissue has the ability to be elongated or stretched, which is known as extensibility. This quality allows muscles to stretch and extend to accommodate movement. For example, when you stretch your arm to reach a high shelf, the muscles in your arm are able to elongate to reach that height.
One example of extensibility in muscle tissue is seen in the fascicles, which are bundles of muscle fibers within a skeletal muscle. These fascicles can stretch and extend to allow for a greater range of motion. Another example is the fast glycolytic (FG) muscle fiber, which primarily uses anaerobic glycolysis and can extend to generate quick bursts of energy.
