Figure 2.16 in your textbook (shown below) shows the timing of sensitive periods for the prenatal development of different organ systems. The dark green bars show when environmental impacts on that system are most pronounced. The light green bars show periods of less rapid development, when effects may occur but are likely to be less severe. Based on this chart, which of the following conclusions is warranted:

???????

Select one:

a. 

Brain development takes so long to happen that it doesn’t matter if exposure to teratogens happens early in development

b. 

The effects of prenatal exposure to teratogens depends largely on when in development the exposure occurred

c. 

Exposure to teratogens during the embryonic period is likely to affect only a few developing systems, and effects are likely to be minor

d. 

Prenatal exposure to teratogens is equally harmful to all developing systems, no matter when exposure happens
