An example of skeletal muscle is?
a. the heart
b. the lungs.
c. the leg
d. the stomach

The correct answer is -

c. the leg.

Skeletal muscle is one of three major categories of muscle tissues (other two being smooth muscle and cardiac muscle.

This is striated muscle tissue, which is voluntary in nature (therefore also termed as voluntary muscle) and lies under the somatic nervous system.

Majority of skeletal muscles are connected to bones with the help of tendons (which are bundles of collagen).

Skeletal muscles provide support to the body and assist in movement. This is because contraction of skeletal muscle allows pulling of tendons, which are basically attached to bone. This assist in movement of legs (such as walking, jumping).

This indicates that every physical activity performed by an organsim is related to skeletal muscle.

Thus, muscles associated with legs are example of skeletal muscles.

Therefore, option c) is the right answer.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

a covalent bond, specfically triple bond
