Answer:

The correct answer is option B, that is, they contract very quickly.

Explanation:

The fast-twitch muscle fibers vary from the slow-twitch muscle fibers as they possess the tendency to generate energy in the non-presence of oxygen. This permits them to generate energy briskly by utilizing glycogen and phosphocreatine, to fuel those brisk explosive motions like sprinting and jumping.

This signifies that the fast-twitch muscle fibers exhibit faster contraction speeds in comparison to the slow-twitch muscle fibers. The fast-twitch muscle fibers are further differentiated into two types. The slow-twitch muscles assist in performing long-endurance activities like distance running, while the fast-twitch muscle fibers are utilized in performing powerful spurts of movements.

Answer:

The defense gets only one try to get a first down.

Explanation:

The first down is the down in a series of four downs in which the offense team is expected to make a 10-yard gain or release the ball to their opponents. The four series of downs are identified as the first, second, third, and fourth downs.

The third option is not correct because when the defense team now has a chance at the ball, they switch sides and then become the offense team. So they would have the adequate number of chances expected of an offense team to get a first down.
