1. 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.

2. Breastfeeding for just a few weeks ________.

A. is a rare practice among American women
B. leads directly to later obesity
C. is not helpful because, in the beginning, breastfeeding causes constipation
D. offers some protection against respiratory and intestinal infections

Correct answer: D

Rationale: Breastfeeding for even a short period offers infants protection against respiratory and intestinal infections. Choice A is incorrect because breastfeeding is not a rare practice among American women. Choice B is incorrect as there is no direct link between breastfeeding for a few weeks and later obesity. Choice C is incorrect as breastfeeding does not cause constipation in infants; in fact, it can help prevent constipation.

3. Most cognitive aging research has focused on intellectual ________.

A. stability
B. gains
C. competence
D. deficits

Correct answer: D

Rationale: The correct answer is 'D: deficits.' Most cognitive aging research has indeed focused on deficits rather than stability, gains, or competence. Studies have consistently shown that deficits in processing speed and memory are common in aging individuals, making it a primary area of interest in research. Choices A, B, and C are incorrect because cognitive aging research primarily aims to understand and address deficits associated with aging rather than focusing on stability, gains, or overall competence.

4. The embryonic disk __________.

A. becomes the new organism
B. is the outer ring of cells on a blastocyst
C. has a good chance of survival outside the womb
D. is a protective membrane that surrounds the amnion Answer: A Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: The embryonic disk becomes the new organism. It is a cluster of cells within the blastocyst that will develop into the fetus during the early stages of prenatal development. This cluster of cells is responsible for giving rise to all the tissues and organs of the developing organism.

5. 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.
