1. Shamona, a pregnant mother in Flint, Michigan, is concerned about the drinking water, which shows high levels of lead. Shamona should know that high levels of prenatal lead exposure are related to __________.

Correct answer: C

Rationale: High levels of prenatal lead exposure are related to low birth weight and brain damage. Lead exposure during pregnancy can have harmful effects on the developing fetus, leading to complications such as decreased birth weight and potential long-term brain damage. Choices A, B, and D are incorrect because they do not directly correlate with the known effects of prenatal lead exposure. While lead exposure can indeed cause a variety of health issues, such as heart defects and urinary tract problems, the primary concerns related to prenatal exposure are low birth weight and brain damage.

2. The yolk sac __________.

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

3. What is a major disadvantage of cross-sectional research?

Correct answer: C

Rationale: One major disadvantage of cross-sectional research is that factors affecting individual development cannot be explored thoroughly. Cross-sectional research involves comparing different groups of people at one specific point in time, and does not allow for tracking individual changes over time. This limitation means that the unique influences and trajectories of individual development may be overlooked in cross-sectional studies. Choices A, B, and D are incorrect. Choice A is not a major disadvantage of cross-sectional research as age-related changes can still be compared across different groups in this type of study. Choice B, while a potential issue in any study, is not specific to cross-sectional research. Choice D refers to a different type of bias caused by repeated testing rather than a major disadvantage of cross-sectional research.

4. During her pregnancy, Padma increased her intake of coffee and tea. Her doctor is likely to tell her that high doses of caffeine contained in coffee and tea increase the risk of __________.

Correct answer: D

Rationale: High doses of caffeine contained in coffee and tea have been linked to an increased risk of low birth weight. Consuming large amounts of caffeine during pregnancy can interfere with the baby's growth and development, leading to a lower birth weight than expected. It is important for pregnant women to limit their caffeine intake to reduce the risk of complications such as low birth weight.

5. By the end of Greta's first month of pregnancy, her embryo __________.

Correct answer: B

Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus. Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.
