Line of scrimmage is the imaginary line that separates the offense and defense
Where are the answer choices?
Answer:
B. Ashchronous recruitment
Explanation:
Asynchronous muscles are muscles that Don't have one-to-one relationship between electrical stimulation and mechanical contraction. Such muscles can be found in About 75% of flying insects and they have convergently evolved 7-10 times.
The synchronous muscles which is their counterparts contracts once per neural signal, but mechanical oscillations trigger force production in asynchronous muscles.
Hence the rate of mechanical contraction is an order of magnitude greater than electrical signals.
Although they achieve greater force output and higher efficiency at high frequencies, they have limited applications because of their dependence on mechanical strength.
The nervous system recruits the Ashchronous muscle to avoid muscle fatigue during submaximal contraction.
The fact that many people came to the US from Europe and the various countries of Africa, as well as the Middle east and Asia. This happened because Europe was destroyed more or less at the time and it didn't present many opportunities for people. Therefore, they moved to the US. And all of this mixing of different ethnicities of people who have seen war and its attrocities lead to a lot of tensions.
