Final answer:
Gravity can minimize elbow flexion by exerting a downward force on the forearm, reducing the torque and force exerted by the biceps muscle.
Step-by-step explanation:
The biceps muscle is responsible for elbow flexion, which is the movement of bending the elbow joint. Gravity can minimize elbow flexion by exerting a downward force on the forearm or hand, counteracting the action of the biceps muscle. As the forearm lifts the weight, it gets closer to the elbow, decreasing the torque placed on the arm and reducing the force exerted by the biceps muscle.
