Question

Quizplus · Accepted Answer

Alcohol is considered the teratogen that causes the most widespread damage to prenatal development in developed countries, leading to a range of physical, cognitive, and behavioral problems collectively known as fetal alcohol spectrum disorders (FASD). This is because alcohol easily crosses the placental barrier and interferes with the fetus's normal growth and development, particularly of the brain and central nervous system. While tobacco, infectious diseases, and cocaine can also have negative impacts on prenatal development, they are not as widespread or severe as the effects of alcohol.
