1. Regarding a baby’s adaptation to labor and delivery, stress hormones __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 21 Test Bank for Berk, Development Through the Lifespan, 7e

• A. endanger the newborn
• B. arouse the infant into alertness
• C. cause the cervix to thin and the uterine wall to contract
• D. cause the mother to breathe deeply, increasing the infant’s oxygen supply Answer: B Page Ref: 94 Skill Level: Understand newborn baby’s appearance. Topic: Childbirth Difficulty Level: Moderate

Correct answer: B

Rationale: Stress hormones during labor and delivery actually help arouse the infant into alertness. These hormones can promote the infant's readiness to adapt to the new environment outside the womb.

2. Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?

• A. The death of a spouse causes a decline in the surviving partner's physical health.
• B. The death of a spouse is related to a decline in the surviving partner's physical health.
• C. A decline in a surviving partner's physical health can cause the death of a spouse.
• D. A third variable, such as memory loss, causes a surviving partner's decline in physical health following the death of a spouse.

Correct answer: B

Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.

3. During the period of the embryo, the __________ becomes the __________.

• A. mesoderm; nervous system, lungs, internal organs, and skin
• B. chorion; endocrine system, muscles, placenta, and skeleton
• C. ectoderm; circulatory system, skin, skeleton, and internal organs
• D. endoderm; digestive system, lungs, urinary tract, and glands Answer: D Page Ref: 78 Skill Level: Remember Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: D

Rationale: During the period of the embryo, the endoderm becomes the digestive system, lungs, urinary tract, and glands. The endoderm is one of the primary germ layers that give rise to various internal organs in the developing embryo. It plays a crucial role in the formation of organs such as the digestive system, respiratory system, and glandular structures.

4. Which of the following best describes a sequential design?

• A. Does not address diversity in developmental outcomes.
• B. Permits researchers to check if cohort effects are operating.
• C. Is less efficient than a longitudinal design.
• D. Makes cross-sectional, but not longitudinal, comparisons.

Correct answer: B

Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.

5. In the eighth month of pregnancy, what typically happens?

• A. fetal growth doubles
• B. neuron production increases
• C. the eyes, ears, nose, jaw, and neck form
• D. lanugo typically is shed

Correct answer: D

Rationale: In the eighth month of pregnancy, lanugo typically is shed. Lanugo is the fine, downy hair that covers a fetus's body to help regulate body temperature while in the womb. By the eighth month, many fetuses shed this hair as they prepare for birth. Choices A, B, and C are incorrect because fetal growth doubling, neuron production increasing, and the formation of eyes, ears, nose, jaw, and neck occur in earlier stages of pregnancy, not specifically in the eighth month.
