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 __________.

• A. facial abnormalities and heart defects
• B. defects of the genitals and urinary tract
• C. low birth weight and brain damage
• D. a variety of childhood cancers

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. During pregnancy, the placenta __________.

• A. forms in the second trimester of pregnancy
• B. encloses the developing organism in amniotic fluid
• C. contains one large vein that delivers nutrients to the embryo
• D. delivers food and oxygen to the developing organism

Correct answer: D

Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.

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

• A. Age-related changes cannot be examined.
• B. Participants often drop out before the study is over.
• C. Factors affecting individual development cannot be explored.
• D. Practice effects often cause biased findings.

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. Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership __________ than comparison-group agemates.

• A. scored lower in impulsivity and overactivity
• B. had lower academic achievement scores
• C. showed more aggressive behavior
• D. reported less alcohol and drug use

Correct answer: D

Rationale: Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership reported less alcohol and drug use compared to their comparison-group agemates. This indicates that the program may have a positive impact in reducing risky behaviors among adolescents whose mothers received home visits. Choices A, B, and C are incorrect because the extract specifically mentions that the children reported less alcohol and drug use, and there is no mention of impulsivity, overactivity, academic achievement scores, or aggressive behavior in this context.

5. According to ecological systems theory, interactions between Marina and her child, Tyler, occur in the __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 20 Test Bank for Berk, Development Through the Lifespan, 7e

• A. microsystem
• B. mesosystem
• C. exosystem
• D. macrosystem Answer: A Page Ref: 23 Skill Level: Apply Topic: Recent Theoretical Perspectives Difficulty Level: Moderate

Correct answer: A

Rationale: According to ecological systems theory, interactions between Marina and her child, Tyler, occur in the microsystem. The microsystem refers to the immediate social context in which an individual lives, such as interactions with family members, friends, and teachers. Marina and Tyler's interactions within their family unit would be considered part of the microsystem.
