Question

which answer choice correctly explains two functions of the muscular system that are illustrated in the image below?
to enable movement and to get rid of heat
to stabilize joints and to maintain posture
to enable movement and to stabilize joints
to get rid of heat and to maintain posture

Explanation:

1. Analyze the image: The person is stretching or moving, and the muscular system's functions here involve movement and joint stabilization.
2. Evaluate options:

• "to enable movement and to get rid of heat": Heat elimination isn't shown. Eliminate.
• "to stabilize joints and to maintain posture": Posture maintenance isn't the main focus here (she's moving, not just holding a posture). Eliminate.
• "to enable movement and to stabilize joints": Movement (stretching/moving) and joint stabilization (needed for such movements) fit.
• "to get rid of heat and to maintain posture": Both heat and posture aspects don't match the action. Eliminate.
• "to get rid of heat and to maintain posture": Same as above, incorrect.

Answer:

to enable movement and to stabilize joints
