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

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. A __________ is a means of building schemes in which an infant who has stumbled onto a new experience caused by his or her own motor activity tries to repeat the event again and again.

Correct answer: B

Rationale: A circular reaction is a process where an infant repeats a specific action to explore and learn about the environment through their own motor activity. This repetition helps the infant to understand the consequences of their actions and build cognitive schemes. Sensorimotor reflex (choice A) refers to automatic responses to stimuli, not a purposeful repetition of actions to learn. Mental representation (choice C) involves internal cognitive structures to represent objects or events in the mind, which is different from the repetitive behavior described in the question. Goal-directed behavior (choice D) is purposeful and intentional, unlike the repetitive nature of circular reactions in infants' learning process.

3. In the United States, the second leading cause of neonatal mortality is __________, which is largely preventable.

Correct answer: C

Rationale: The second leading cause of neonatal mortality in the United States is low birth weight, which is largely preventable through proper prenatal care, nutrition, and health interventions. Low birth weight infants are at higher risk for various health complications and mortality, making it an important issue to address in maternal and child health programs. Malnutrition (choice A) can contribute to low birth weight but is not the direct cause of neonatal mortality. Physical abnormality (choice B) can be a factor in some cases but is not the second leading cause overall. Sudden infant death syndrome (choice D) refers to unexplained deaths of seemingly healthy babies and is not related to low birth weight as a leading cause of neonatal mortality.

4. You can tell her that healthy women in their thirties have __________ as those in their twenties.

Correct answer: D

Rationale: Healthy women in their thirties typically have about the same rates of pregnancy complications as those in their twenties. While it is true that the risk of fertility issues and certain pregnancy complications may increase with age, generally speaking, women in their thirties who are healthy and do not have preexisting conditions do not necessarily experience higher rates of pregnancy complications compared to women in their twenties.

5. A childbirth leave of __________ predicts favorable maternal physical and mental health, supportive marital interaction, and sensitive caregiving.

Correct answer: D

Rationale: Research indicates that a childbirth leave of 12 weeks or more leads to favorable outcomes for maternal physical and mental health, supportive marital interaction, and sensitive caregiving. This extended period of leave allows mothers to recover physically, adjust psychologically, and establish strong bonds with their newborn, which ultimately benefits the whole family. Choices A, B, and C are incorrect as they do not provide the optimal duration needed for mothers to experience the full range of benefits associated with an extended childbirth leave.
