1. 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.

2. Bernadette, a participant in a longitudinal study, became quite familiar with the test over time and, as a result, her performance improved. This limitation of longitudinal research is known as __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 34 Test Bank for Berk, Development Through the Lifespan, 7e

• A. biased sampling
• B. practice effects
• C. random assignment
• D. cohort effects Answer: B Page Ref: 35 Skill Level: Apply Topic: Studying Development Difficulty Level: Moderate

Correct answer: B

Rationale: Practice effects refer to the phenomenon where participants in a longitudinal study show improvement in test performance over time due to becoming familiar with the tasks or test materials. This can be considered a limitation as it may distort the results by showing an artificial improvement rather than a true developmental change.

3. When the blastocyst burrows deep into the uterine lining, __________.

• A. implantation occurs
• B. pregnancy does not occur
• C. it stops growing
• D. the cells of the zygote first duplicate

Correct answer: A

Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.

4. The harm done by teratogens __________.

• A. is straightforward and predictable
• B. is usually apparent at birth
• C. rarely goes beyond physical damage
• D. depends on age at the time of exposure

Correct answer: D

Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.

5. Students who are foreign-born or first-generation Americans _______ than students of native-born parents.

• A. are more likely to commit delinquent and violent acts
• B. are more likely to be obese
• C. often achieve in school as well as or better
• D. tend to report lower self-esteem

Correct answer: C

Rationale: According to the information provided in the text box 'CULTURAL INFLUENCES: Immigrant Youths: Adapting to a New Land' on page 32, students who are foreign-born or first-generation Americans often achieve in school as well as or better than students of native-born parents. This implies that they excel academically despite facing challenges related to cultural adaptation and assimilation. Choices A, B, and D are incorrect because the provided information specifically highlights the academic achievement of foreign-born or first-generation American students compared to students of native-born parents, not their likelihood of committing delinquent acts, obesity rates, or self-esteem levels.
