Answer/Explanation:
EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.
A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.
Weather patterns and soil conditions.

Explanation:
Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes.

The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.
