Final answer:
The skeletal and muscular systems work together to provide support and movement in the body. If either system malfunctions, movement and support would be affected.
Step-by-step explanation:
The skeletal and muscular systems work together to provide support and allow for movement in the body. The skeletal system consists of bones that protect internal organs and support the body's weight. The muscular system consists of muscles that contract and pull on the bones to produce movement.
If the skeletal system were not functioning properly, it would affect movement and support in the body. Without the skeletal system, the body would be unable to maintain proper posture, perform basic movements, and protect internal organs.
Similarly, if the muscular system were not functioning properly, it would also affect movement. Muscular weakness or paralysis would make it difficult or impossible to move the body or perform tasks that require muscle contraction.
