1. The yolk sac __________.

• 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. In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to __________.

• A. lower birth weight and higher risk of premature birth
• B. suppressed development of the immune system
• C. serious damage to the central nervous system
• D. improved fetal cardiovascular functioning

Correct answer: D

Rationale: In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to improved fetal cardiovascular functioning. Regular exercise has been shown to benefit both the mother and baby by promoting better cardiovascular health and overall well-being during pregnancy. Choices A, B, and C are incorrect as exercise during pregnancy, when done appropriately, does not lead to lower birth weight, higher risk of premature birth, suppressed immune system development, or serious damage to the central nervous system. Instead, it is known to have positive effects on fetal development and maternal health.

3. Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress __________.

• A. nature over nurture
• B. changes in thinking
• C. unconscious motives and drives
• D. the effects of punishment and reinforcement on behavior Answer: B Page Ref: 26 Skill Level: Understand development. Topic: Comparing and Evaluating Theories Difficulty Level: Difficult

Correct answer: B

Rationale: Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress changes in thinking. These theories focus on how cognitive abilities develop over time, emphasizing the growth and transformation of thinking processes rather than static traits or characteristics.

4. Which statement is supported by research on newborn taste preferences?

• A. Newborns cannot distinguish basic tastes.
• B. Not until 4 months do babies prefer a salty taste to plain water.
• C. Newborns prefer the taste of formula to breast milk.
• D. Unlike adults, babies relax their facial muscles in response to sour tastes.

Correct answer: B

Rationale: Research on newborn taste preferences has found that not until around 4 months of age do babies start to show a preference for a salty taste over plain water. This indicates that newborns do have some ability to distinguish tastes, contrary to the statement in option A. The statement in option C that newborns prefer the taste of formula to breast milk is not supported by research on newborn taste preferences. Option D, stating that babies relax their facial muscles in response to sour tastes, is also not a supported statement regarding newborn taste preferences.

5. Depression __________.

• A. declines with age
• B. responds to treatment that is completely covered by Medicare
• C. is rarely related to physical illness or pain
• D. can lead to cognitive deterioration

Correct answer: D

Rationale: The correct answer is D: 'can lead to cognitive deterioration.' Depression, particularly in older adults, can significantly impair cognitive function, leading to further mental health challenges. Choices A, B, and C are incorrect. Depression does not necessarily decline with age, treatment coverage may vary, and depression can indeed be related to physical illness or pain.
