The uterine phase where the thickness of the endometrium doubles is the

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 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.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
