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. What is one strength of the cross-sectional design?

• A. It provides evidence about individual trends.
• B. It cannot be threatened by cohort effects.
• C. It is not plagued with dropout or practice effects.
• D. It permits longitudinal comparisons. Answer: C Page Ref: 34 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate

Correct answer: C

Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.

3. During her pregnancy, Padma increased her intake of coffee and tea. Her doctor is likely to tell her that high doses of caffeine contained in coffee and tea increase the risk of __________.

• A. premature labor
• B. limb deformities
• C. respiratory distress at birth
• D. low birth weight Answer: D Page Ref: 83 Skill Level: Apply known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Difficult

Correct answer: D

Rationale: High doses of caffeine contained in coffee and tea have been linked to an increased risk of low birth weight. Consuming large amounts of caffeine during pregnancy can interfere with the baby's growth and development, leading to a lower birth weight than expected. It is important for pregnant women to limit their caffeine intake to reduce the risk of complications such as low birth weight.

4. Around __________, Baby Alanna should begin to prefer a salty taste to plain water.

• A. 2 weeks
• B. 6 weeks
• C. 2 months
• D. 4 months

Correct answer: D

Rationale: At around 4 months of age, babies begin to develop a preference for salty taste over plain water. This preference is part of their sensory development and exploration of tastes. Introducing a variety of flavors, including salty tastes, at this stage helps broaden the baby's palate and acceptance of different foods later on. Choices A, B, and C are incorrect as babies typically do not develop a preference for salty tastes over plain water at 2 weeks, 6 weeks, or 2 months of age. These earlier stages are more focused on milk feeding and the introduction of solid foods usually begins around 4-6 months of age.

5. Which statement about prenatal rubella is true?

• A. The greatest damage occurs when rubella strikes during the fetal period.
• B. The organ damage inflicted by prenatal rubella can lead to lifelong health problems. Copyright © 2018 Laura E. Berk. All Rights Reserved. 15 Test Bank for Berk, Development Through the Lifespan, 7e
• C. Routine vaccination has made new rubella outbreaks extremely rare worldwide.
• D. Infection during the embryonic period is less harmful than during other prenatal periods. Answer: B Page Ref: 86‒87 Skill Level: Understand known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: B

Rationale: The statement that the organ damage inflicted by prenatal rubella can lead to lifelong health problems is true. Rubella infection during pregnancy can cause serious harm to the developing fetus, including organ damage, deafness, heart defects, and intellectual disabilities. This highlights the importance of prevention and vaccination to protect both pregnant women and their unborn babies from the harmful effects of rubella.
