Answer:
At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.
Explanation: The potential soil erosion increases if the soil has no or very little vegetative cover of plants/grass and/or crop residues. Plant and residue cover protects the soil from rain impact and splashes from it. It tends to slow down the movement of runoff water and allows excess surface water to infiltrate.

Explanation:
<h3><u>Answer;</u></h3>
acceleration= 2 m/s²
<h3><u>Explanation;</u></h3>
From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.
That is;
F = ma
Thus; F = 100 N, m = 50 kg
a = F/m
= 100/50
= 2 m/s²
