When the z disk moves toward the M line the muscles contract true or false

True.

Explanation:

The sliding filament model states that, during muscular contraction, each sarcomere is shrunk, moving the Z disks closer together and towards the M line. The amplitude of the A band doesn't change, but both the I bands and the H zone almost completely disappear. This happens because the actin and myosin filaments slide against one another, thus the actin filaments occupy the A band and the H zone.

not too sure but maybe in the hot springs.

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.
