1. The yolk sac __________.

• A. forms during the third trimester of pregnancy
• B. is the outer ring of cells that surrounds the blastocyst Copyright © 2018 Laura E. Berk. All Rights Reserved. 3 Test Bank for Berk, Development Through the Lifespan, 7e
• C. produces blood cells until the organs are mature enough to take over this function
• D. contains one large vein that delivers blood loaded with nutrients and two arteries that remove waste Answer: C Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. Recent evidence suggests that paternal alcohol use around the time of conception __________.

• A. can alter gene expression
• B. can cause fetal alcohol syndrome
• C. is linked to blood vessel abnormalities
• D. has no negative effect on the developing organism

Correct answer: A

Rationale: Recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression. This means that paternal alcohol consumption can potentially impact the genes and genetic materials passed on to offspring, affecting their development and health. Choice B is incorrect because fetal alcohol syndrome is typically associated with maternal alcohol consumption during pregnancy, not paternal alcohol use around conception. Choice C is incorrect as there is no direct link between paternal alcohol use and blood vessel abnormalities. Choice D is incorrect as paternal alcohol use can indeed have negative effects on the developing organism, particularly through altering gene expression.

3. Terrance, whose birth mother drank heavily throughout pregnancy, has a thin upper lip, short eyelid openings, a small head, and a smooth philtrum. His physical growth has been slow, and he shows impairment in memory, attention span, motor coordination, and social skills. Terrance has __________.

• A. fetal alcohol syndrome
• B. partial fetal alcohol syndrome
• C. alcohol-related neurodevelopmental disorder
• D. cytomegalovirus

Correct answer: A

Rationale: Terrance exhibits a combination of physical abnormalities like a thin upper lip, short eyelid openings, a small head, and a smooth philtrum, along with developmental delays and cognitive impairments. These characteristics are indicative of fetal alcohol syndrome (FAS), which is caused by maternal alcohol consumption during pregnancy. FAS is a severe condition resulting from prenatal alcohol exposure and is characterized by a range of physical, cognitive, and behavioral issues. Choice A, fetal alcohol syndrome, is the correct answer as it aligns with Terrance's symptoms and the effects of maternal alcohol consumption during pregnancy. Choices B, C, and D are incorrect because they do not encompass the full spectrum of symptoms and impairments presented by Terrance, which are specific to fetal alcohol syndrome.

4. What increases from early to middle adulthood?

• A. Possible selves
• B. Self-doubt
• C. Destructiveness
• D. Autonomy

Correct answer: A

Rationale: Possible selves are ideas about what one might become in the future, which increase during the transition from early to middle adulthood. This period is characterized by individuals exploring and considering different potential future selves. Self-doubt (choice B) typically decreases as individuals become more confident and self-assured in middle adulthood. Destructiveness (choice C) is not a common developmental trend during this period. Autonomy (choice D) is a concept related to independence and self-governance, which may develop over a person's lifespan but does not specifically increase during the transition from early to middle adulthood.

5. 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.
