Question

In order for the bicep muscle to shorten, the force applied by the muscle must be ________ the load applied at the hand.

A) greater than
B) less than
C) equal to

Answer 1

In order for the bicep muscle to shorten, the force applied by the muscle must be greater than the load applied at the hand. Option A is the answer.

Step-by-step explanation:

Muscle contraction involves the bicep generating a force to overcome an external load. For the bicep muscle to shorten and lift a load at the hand, the force applied by the muscle must be greater than the resistance provided by the load. This process follows the basic principles of muscle mechanics. If the force applied by the bicep is less than the load, the muscle will not be able to overcome the resistance, and no shortening or lifting will occur. On the other hand, when the muscle exerts a force greater than the load, it can contract, causing the bicep to shorten and lift the load.

Option A is the answer.
