Explanation:
As the two plates move away from each other in a divergent boundary, the magma from the mantle beneath rises to replace the void created. The magma then cools into a new crust. Before the magma cools, the iron minerals align themselves with the magnetic fields of the earth due to their ferromagnetic properties. These cause the rocks after they are cooled to seem to have bands.
Due to magnetic reversals of the earth's magnetic fields (i.e change in magnetic north and south poles) over several hundred thousand years, these bands will orient differently depending on the then earth magnetic polarity when the magma was cooling.

Answer:
Proliferative phase
Explanation:
Uterine cycle is part of the menstrual cycle in which changes occur in the reproductve female system in order to prepare female on possible pregnacy. Uterine cycle isdivided into three phases:
- Menstrual phase-characterized by the process of menstruation
- Proliferative phase-estogen causes the production of new endomethrium layer (thickening of the endomethrium)
- Secretory phase-characterized by the production of progesteron which prepares endomethrium for the implementation.
