1.Muscles have the primary objective to work in pair, in order to be able to move the bone freely in all directions, without this pairs the bone could only move in 2 directions.
2.The skeltal muscle have many diffrents parts, some of them are the muscle fibers, inside this we can find nuclei inside them we also find the type of filament.
3.- the skeletal system because of the bones doing the hand shake.-the integumentary system in the skin of our hands.-the nervous system when we make the decision of the handshake
4.first the myosin attaches to the acting filament, and bends.Then the myosinreleases the actin and attaches itself in another part of the acting and keeps pulling it until the actin filament is fully contracted.
I think your answers are good but you have to complete them more for example to explain better the process of the myosin and the actin and explain the part when the atp separates the myosin from the actin
ReplyDeleteyou should elaborate the answers... they are kind of short and dont show thoroughness
