1. In females, the twenty-third pair of chromosomes is labeled as __________.

A. an autosome
B. dizygotic
C. XX
D. XY

Correct answer: C

Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.

2. Lillian uses flowcharts to map the precise steps individuals use to solve problems and complete tasks. Lillian is a(n) __________ theorist.

A. psychoanalytic
B. information-processing
C. psychosocial
D. social learning Answer: B Page Ref: 19 Skill Level: Apply Topic: Recent Theoretical Perspectives Difficulty Level: Moderate

Correct answer: B

Rationale: Lillian, who uses flowcharts to map precise steps individuals use to solve problems and complete tasks, is likely an information-processing theorist. Information-processing theorists focus on how people take in, store, and retrieve information to solve problems and make decisions, which aligns with Lillian's use of flowcharts to map out problem-solving steps.

3. Increasingly, researchers __________.

A. assume that development stops at adolescence
B. view old age as a period of decline
C. view heredity as more influential than the environment
D. see development as a perpetually ongoing process Answer: D Page Ref: 7 Skill Level: Understand Topic: The Lifespan Perspective: A Balanced Point of View Difficulty Level: Moderate Copyright Ã‚Â© 2018 Laura E. Berk. All Rights Reserved. 4 Test Bank for Berk, Development Through the Lifespan, 7e

Correct answer: D

Rationale: Increasingly, researchers see development as a perpetually ongoing process. This perspective emphasizes that development continues throughout the lifespan, rather than stopping at a particular age like adolescence. Researchers now focus on understanding how individuals change and grow over time, recognizing that development is a lifelong journey influenced by both biological and environmental factors.

4. What is the function of the amniotic fluid?

A. Delivers food and oxygen to the developing organism
B. Helps keep the temperature of the prenatal world constant
C. Delivers nutrients and removes waste products
D. Produces blood cells until the organs are mature enough to take over this function

Correct answer: B

Rationale: The correct answer is B: 'Helps keep the temperature of the prenatal world constant.' Amniotic fluid helps maintain a stable and warm environment for the developing organism, assisting in regulating the temperature. This fluid also acts as a cushion, protecting the fetus from physical harm. Choices A, C, and D are incorrect because while amniotic fluid provides protection and support to the developing organism, it does not directly deliver food, oxygen, nutrients, or remove waste products, nor does it produce blood cells as the organs eventually take over this function.

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.
