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. If pregnancy does not occur, the corpus luteum shrinks, and the __________.

• A. cells begin to duplicate
• B. one-celled zygote multiplies and forms a blastocyst
• C. germinal period lasts only about two weeks
• D. lining of the uterus is discarded

Correct answer: D

Rationale: If pregnancy does not occur, the corpus luteum will shrink. As a result, the lining of the uterus is discarded through the process of menstruation. This shedding of the uterine lining is what causes menstrual bleeding. Choices A, B, and C are incorrect because they do not describe the physiological response of the body when pregnancy does not occur. The corpus luteum shrinking and the subsequent shedding of the uterine lining are part of the menstrual cycle, not processes related to cell duplication, zygote multiplication, or the duration of the germinal period.

3. Tammy's father is an exceptional gymnast. When Tammy was just a toddler, her father believed that Tammy already showed great promise as a gymnast. Tammy's father probably believes that athletic ability is mostly determined by __________.

• A. nurture
• B. stages
• C. nature
• D. early experiences

Correct answer: C

Rationale: Tammy's father likely believes that athletic ability is mostly determined by nature because he believes she showed great promise at a young age, indicating a natural talent or genetic predisposition towards gymnastics. This suggests that he attributes Tammy's abilities to her inherent qualities rather than her upbringing or experiences (nurture). While stages and early experiences can play a role in skill development, in this context, the emphasis is on innate abilities, making 'nature' the most suitable choice.

4. Unlike Jean Piaget, Lev Vygotsky viewed cognitive development as a _________ process.

• A. socially mediated
• B. genetically predictable
• C. preoperational
• D. neurological

Correct answer: A

Rationale: Lev Vygotsky viewed cognitive development as a socially mediated process, emphasizing the role of social interactions and cultural influences in shaping a child's cognitive development. This is in contrast to Jean Piaget, who focused more on individual interactions with the environment. Vygotsky believed that cognitive development is significantly influenced by social interactions with others, highlighting the importance of collaborative learning and cultural context. Choices B, C, and D are incorrect as they do not align with Vygotsky's perspective on cognitive development.

5. Two-year-old Eva's parents meet her assertions of independence with tolerance and understanding. They provide suitable guidance and reassurance. According to Erikson's theory, Eva will develop __________ as a result.

• A. basic trust
• B. mistrust
• C. autonomy
• D. industry

Correct answer: C

Rationale: According to Erikson's theory of psychosocial development, when parents support a child's growing independence with guidance and reassurance, the child develops a sense of autonomy. Autonomy is characterized by a growing sense of self-control, confidence, and independence. Basic trust (choice A) is associated with the first stage of Erikson's theory (trust vs. mistrust) during infancy. Mistrust (choice B) arises when a child's basic needs are not met consistently, leading to a lack of trust in the world. Industry (choice D) is related to Erikson's later stages of development and involves competence and productivity in work and tasks.
