Problem: Understanding prenatal development is particularly difficult, partially because pregnant women are considered a vulnerable population, meaning there are stricter regulatory requirements to carry out research on pregnant women and fetuses. What impact do you think these restrictions have had on our understanding of prenatal development? In an ideal world, how would you design an experiment to examine the effects of specific substances on pregnancy? For example, how would you determine if taking prenatal vitamins is helpful or that exposure to pollutants is harmful to the developing fetus? What ethical and practical implications would you have to consider in designing and implementing your study? Need Assignment Help?
