1. 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.

2. __________ coping is largely emotion-focused and self-blaming, impulsive, or escapist.

A. Avoidant
B. Ineffective
C. Problem-focused
D. Flexible

Correct answer: A

Rationale: The correct answer is A: 'Avoidant.' Avoidant coping refers to strategies that involve avoiding the problem and focusing more on emotions. This type of coping mechanism can often lead to negative outcomes as individuals may engage in self-blaming, impulsive behaviors, or seek escapist routes rather than addressing the issue directly. Choice B, 'Ineffective,' is a broad term and does not specifically capture the characteristics described in the question. Choice C, 'Problem-focused,' is the opposite of avoidant coping as it involves actively addressing the issue at hand. Choice D, 'Flexible,' does not align with the description provided, as flexibility in coping involves adapting strategies based on the situation, not necessarily being emotion-focused, self-blaming, impulsive, or escapist.

3. In a longitudinal design, participants are studied repeatedly at different ages, and changes are noted as they get older.

A. cross-sectional
B. experimental
C. longitudinal
D. correlational

Correct answer: C

Rationale: The correct answer is C: longitudinal. In a longitudinal design, participants are followed and studied over an extended period, allowing researchers to observe changes and continuity in development as individuals age. This design is crucial for understanding how individuals grow and change over time. Cross-sectional studies (Choice A) involve comparing different groups at the same time point, while experimental studies (Choice B) involve manipulating variables to observe their effects. Correlational studies (Choice D) examine relationships between variables but do not involve studying participants over time.

4. What is the function of the corpus luteum?

A. is where fertilization usually takes place
B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
C. is one of two long, thin structures that lead to the hollow, softly lined uterus
D. is one of two walnut-sized organs located deep inside a woman's abdomen

Correct answer: B

Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.

5. As a generation, the baby boomers are __________ than any previous mid- or late-life cohort.

A. healthier, but less educated
B. more educated, but less wealthy
C. more self-focused, but less healthy
D. healthier, better educated, and financially better off Answer: D Page Ref: 13 Box: CULTURAL INFLUENCES: The Baby Boomers Reshape the Life Course Skill Level: Remember Topic: The Lifespan Perspective: A Balanced Point of View Difficulty Level: Moderate

Correct answer: D

Rationale: The baby boomers are healthier, better educated, and financially better off than any previous mid- or late-life cohort. This generation has generally enjoyed higher levels of education, advancements in healthcare, and increased economic opportunities, leading to improved overall well-being compared to earlier generations.
