Explanation / Answer

1) environmental factors that affect a baby's prenatal development are roofed under a term called teratogen. These teratogen affect a baby in a contextual manner. Their effect relies on various factor listed as below :

- duration of exposure

- levels/intensity/amounts of exposure

-genetic makeup/ heredity

- tolerance threshold

- interaction effect

Each of the factors vary from mother to mothe and baby to baby as a result of which what might be harmful to one may one affect the other at all
