Step-by-step explanation:

When do teratogens pose the highest degree of risk?

Teratogens pose the highest degree of risk during the

first trimester of pregnancy

. This is because the first trimester is a critical period of development when the organs and systems of the fetus are forming. Exposure to teratogens during this time can lead to birth defects and other developmental abnormalities. It is important for pregnant women to avoid exposure to teratogens during this stage to minimize the risk to the baby.
