A: arm bends and bicep contacts?
B:arm bends and bicep relaxes?
C:arm straightens and bicep relaxes ?
D:arm straightens and bicep contacts?

Answer 1

Answer:

When the biceps contract the triceps will relax, this allows our arm to bend. When we want to straighten our arm back out, the biceps will relax and the triceps will contract. Muscle pairs allow us to move back and forth. All muscles work in pairs to provide movement and stability to the areas they affect.

Answer 2

B : arm bends and bicep relaxes
