Answer:
Fraternal - 2 egg cells
Identical - split of zygote
Explanation:
Fraternal twins are likely to be formed by 2 different egg cells being simultaneously sent by the ovaries and both of them being fertilized by the sperm cells. They are non-identical because the DNA of the 2 egg cells and the 2 sperm cells are different.
Identical twins are formed after a single egg cell has been fertilized by a single sperm cell, then split after the first division. This results in 2 genetically identical embryos because they were formed from the same fertilized egg.

Answer:
In most cyclic movements, the ability of muscles to quickly relax or reduce tone and muscle strength allows for more efficient expression of agonist muscle strength during certain phases of movement.
Explanation:
Several movements are based on relatively short activities of the corresponding muscle groups (rapid individual movements or postural corrections) or alternating activations of antagonistic muscle groups (walking, running, throwing, kicking). The time required to perform most of these movements is limited and is often equal to the duration of explosive operations.
