Please help. I'll give brainliest :) Choose the geologic formation that fits the description: rocks are stretched, moved vertically into blocks, and dropped; the lower blocks are called graben and the taller blocks called horst.
lifted fault block mountains
ocean ridges
tilted fault block mountains
folded mountains

Horsts and Grabens - A narrow block dropped down between two normal faults is called a graben (looks like a small valley). The upraised block is called a horst (looks like a plateau). Normal faults are the dominant structures along the oceanic ridge, and in continental rifts.

Explanation:

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
