Question 3

Identify one disease, one drug, and one environmental hazard that is known to negatively affect prenatal development. Be sure to describe the specific impact of each teratogen.

Accepted Answer

When a woman contracts chicken pox during pregnancy, it can cause spontaneous abortion, developmental delays, or intellectual disabilities.
