Which of the following is defined as any agent that can cause a birth defect?

Teratogen

Explanation

Teratogen: Substance causing birth defects.

Which period of prenatal development is particularly sensitive to the effects of teratogens?

Embryonic period

Explanation

Embryonic period: Early stage vulnerable to teratogens.

Which of the following is a common recommendation for pregnant women to minimize exposure to teratogens?

Limiting caffeine intake

Explanation

Limit caffeine to reduce teratogen exposure.

Which of the following is NOT a potential impact of exposure to teratogens during prenatal development?

Increased risk of allergies

Explanation

Teratogens don't increase allergy risk in prenatal development.

Which of the following is a potential consequence of maternal exposure to certain medications during pregnancy?

Birth defects

Explanation

Certain medications can cause birth defects.

Explanation

Valproic acid: Linked to neural tube defects.

#10

What is the critical period of prenatal development?

The period of time during pregnancy when the fetus is most vulnerable to teratogens

Explanation

Critical period: Fetus most vulnerable to teratogens.

#11

Explanation

Impact of teratogens involves multiple factors.

#17

What is the term for the occurrence of multiple birth defects resulting from exposure to a teratogen?

Sequence

Explanation

Sequence: Multiple defects from teratogen exposure.

#18

What is the term used to describe the process of teratogen-induced cell death during prenatal development?

Apoptosis
