Answer 2

It's actually not that bad just read the lesson 4 muscles fibers lesson or look up an article on muscle contractions and write a small essay, it's quite short . I'll give you a small preview of what I wrote;

"A muscle contraction is when you flex or move your muscle. It involves the shortening of the muscle while applying pressure or force when working. Muscle contractions enable us to move. When your muscle fibers create tension they may shorten. The nervous system controls all the muscles in our body. They send signals through our spinal cords and brains. It travels along the neurons which make up the nervous system, until it reaches the muscles. That electrical signal triggers a reaction in the muscles which causes the muscle to move."

I don't suggest you copy my essay for yours and mines sake lol good luck
