Answer:
<h2>Actin and myosin.</h2>
Explanation:
The cells that allow your bones to move, the movement of thick (myosin) and thin (actin) filaments during contraction
.
During a contraction thick and thin filaments do not shorten but increase their overlap of each other.
Thin filaments slide past thick filaments extending more deeply into the A band.
The I bands and H bands decrease in lenght as Z discs are come closer together

Sarcomere represents area between two Z disc, so the sarcomere gets smaller during a contraction
.
A. The bonds between the individual monomers of a polymer are broken by the addition of water molecules.
