Final answer:
Skeletal muscles contract and pull on bones, which act as levers around joints to produce movement. Bones provide the structure but do not contract; they act as levers when muscles exert force.
Step-by-step explanation:
The correct answer to the student's question is: muscles contract and exert force on the bone, which acts as a lever to stimulate movement. The skeletal muscles are attached to bones by tough connective tissues known as tendons. During movement, muscles that span across joints shorten (contract) and pull on the bones.
These contractions generate force, causing the bones to act as levers, with the joints acting as fulcrums, consequently producing movement. It is important to note that bones do not contract but rather serve as rigid structures for muscle attachment and force transmission.
