Question

What is a teratogen? Identify 3 teratogens and their impact on a developing fetus. Explain what factors determine whether or not a teratogen will be harmful.

a) A teratogen is a type of attachment theory. Teratogens include alcohol, caffeine, and physical activity during pregnancy. Their impact on a developing fetus depends on genetic factors.
b) A teratogen is a substance or factor that can cause birth defects. Examples include alcohol, tobacco, and certain medications. The impact on a developing fetus varies based on the timing, dose, and genetic susceptibility.
c) A teratogen is a type of prenatal test. Teratogens include ultrasounds, amniocentesis, and chorionic villus sampling. Their impact on a developing fetus depends on the accuracy of the test.
d) A teratogen is a type of prenatal care. Teratogens include nutritional supplements, exercise, and rest. The impact on a developing fetus depends on the mother's overall health.

Answer 1

A teratogen is any environmental agent that causes damage to the developing embryo or fetus. Examples of teratogens include alcohol, tobacco, and certain medications. The impact on a developing fetus depends on factors such as timing, dose, and genetic susceptibility.

Step-by-step explanation:

A teratogen is any environmental agent-biological, chemical, or physical-that causes damage to the developing embryo or fetus. Examples of teratogens include alcohol, tobacco, and certain medications. Alcohol, in particular, can lead to fetal alcohol spectrum disorders (FASD) which can result in physical and cognitive abnormalities in children. The impact of teratogens on a developing fetus depends on factors such as timing, dose, and genetic susceptibility.
