Liula [17]

Answer:

Jennifer should understand that exposure to teratogens can cause the most damage during exposures such as <em>the duration of exposure, the amount of teratogenic substance, and the stage of development the embryo or fetus is in during the exposure. </em>

Explanation:

<em>Teratogens</em> may affect the embryo or fetus in a number of ways, causing physical malformations, problems in the behavioral or emotional development of the child, and decreased intellectual quotient (IQ) in the child. Additionally, <em>teratogens</em> may also affect pregnancies and cause complications such as preterm labors, spontaneous abortions, or miscarriages. <em>Teratogens </em>are classified into four types: physical agents, metabolic conditions, infection, and finally, drugs and chemicals.

A loss of all microbes would be terrible news for living organisms that can't create or take in these essential nutrients on their own.
