The development of the embryo is most likely to be severely impacted by exposure to harmful chemicals and radiation (mutagens) during the first trimester because Choose one: A. extensive differentiation of tissues and organs occur during the first trimester and mutagens can cause impaired development. B. its circulatory and respiratory systems are preparing for life in a gaseous atmosphere rather than the watery world of the amniotic fluid. C. mutagens can affect the secretion of the estrogen, oxytocin, and prostaglandins that are vital to development in the first trimester. D. it is accumulating fat and growing in weight during the first trimester.

Which of the following is true of human development? a. Most organs begin to form during the second trimester. b. Gastrulation takes place in the oviducts. c. Genetic diseases can be detected by sampling cells from the chorion. $d .$ Implantation occurs through interactions of the zona pellucida with the uterine lining. e. Exposure to drugs and chemicals is most likely to cause birth defects when it occurs in the third trimester.
Regarding prenatal teratogen exposure, which of the following statements is FALSE? 1. Exposure to teratogens during critical developmental periods will have more severe effects on the fetus. 2. Embryo lethality becomes more likely as the toxic dose is increased. 3. Major effects include growth retardation and malformations. 4. The immune system of the fetus is primitive, so the fetus has little to no ability to fight off chemicals and repair itself. 5. There is considered to be a toxin level threshold below which the fetus is capable of repairing itself.
