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.
Maybe the decrease in plants they eat
Otherwise known as deforestation
Anatomy is the best answer
The right answer is Child abuse.
Cannabis (marijuana) during pregnancy is dangerous for the fetus
During pregnancy, the active component of cannabis, which is THC (tetrahydrocannabinol), can go into the placenta and affect the fetus, including its birth weight (like the case in the question here) and brain function, reducing the baby's IQ and attention capacity.
Depending on the type of drug and the quantity consumed, it is also possible that the baby suffers from weaning at birth, that is to say from deprivation (inconsolable crying, irritability, tremors, feeding difficulties, etc.). .
Cannabis may also have longer-term effects in children (learning disabilities, behavioral problems, hyperactivity, etc.).
