How do muscles work in antagonistic pairs? the muscles alternate, producing wavelike contractions. each muscle is attached to a different ligament. both muscles always contract at the same time. when one muscle pulls, the other muscle relaxes.

Muscles work in antagonistic pairs when one muscle pulls, the other muscle relaxes.

Explanation:

Antagonistic pair of muscles works by opposing each other's action. This happens because the skeletal muscles that control the movement of bones move unidirectional and can contract or pull in that direction only.

Skeletal muscle movement takes place with contraction of one muscle and relaxation of another muscle. Straightening and bending movements are antagonist type of movements and are provided by the flexor and extensor muscles which antagonize their actions.

During an elbow bending movement of the biceps-triceps muscle pair, the biceps contracts and acts as the agonist and the triceps relaxes or flexes and acts as the antagonist.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
