1. Which statement about a blastocyst is true?

• A. It consists of a single cell.
• B. It is a structure that feeds the developing organism.
• C. Between the seventh and ninth days, it burrows deep into the uterine lining.
• D. It is a membrane that helps to keep the temperature of the prenatal world constant.

Correct answer: C

Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.

2. You can tell her that healthy women in their thirties have __________ as those in their twenties.

• A. lower rates of miscarriage Copyright © 2018 Laura E. Berk. All Rights Reserved. 18 Test Bank for Berk, Development Through the Lifespan, 7e
• B. higher rates of pregnancy complications
• C. lower rates of pregnancy complications
• D. about the same rates of pregnancy complications Answer: D Page Ref: 89 Skill Level: Apply Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: D

Rationale: Healthy women in their thirties typically have about the same rates of pregnancy complications as those in their twenties. While it is true that the risk of fertility issues and certain pregnancy complications may increase with age, generally speaking, women in their thirties who are healthy and do not have preexisting conditions do not necessarily experience higher rates of pregnancy complications compared to women in their twenties.

3. Among all Western nations, which country has the highest percentage of extremely poor children?

• A. the United States
• B. Canada
• C. Germany
• D. France

Correct answer: A

Rationale: The correct answer is 'the United States.' According to the information provided, the United States has the highest percentage of extremely poor children among Western nations. This is supported by the extract, which states that the United States leads in this aspect. Choices B, C, and D are incorrect as the question specifically asks for the country with the highest percentage of extremely poor children among Western nations, which is the United States.

4. Researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom. This is an example of a __________.

• A. naturalistic observation
• B. case study
• C. natural experiment
• D. field experiment

Correct answer: D

Rationale: In this scenario, the researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom, which is an example of a field experiment. A field experiment involves manipulating independent variables in a natural setting to observe the effects on participants. This design allows for more control over variables compared to naturalistic observation, case studies, or natural experiments. Naturalistic observation involves observing subjects in their natural environment without manipulating any variables. A case study focuses on in-depth analysis of a single individual or a small group. A natural experiment involves observing naturally occurring events without intervention or manipulation by the researcher.

5. The more alcohol a woman consumes during pregnancy, the __________.

• A. higher the birth weight of the child
• B. greater the likelihood of ARND instead of FAS or p-FAS
• C. poorer the child's achievement scores in the school years
• D. greater the child's speed of information processing

Correct answer: C

Rationale: The correct answer is C: 'poorer the child's achievement scores in the school years.' Prenatal exposure to alcohol has been linked to a range of cognitive and behavioral difficulties, including lower academic achievement in children. These difficulties may manifest as poor achievement scores in later school years. Choices A, B, and D are incorrect because alcohol consumption during pregnancy is not associated with higher birth weight of the child, the likelihood of ARND instead of FAS or p-FAS, or greater speed of information processing in the child.
