1. To study the impact of biological aging on motor skills, researchers focus on __________.

• A. sedentary adults
• B. competitive athletes
• C. men in their mid- to late thirties
• D. women in their childbearing years

Correct answer: B

Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.

2. 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.

3. What is the function of the corpus luteum?

• A. is where fertilization usually takes place
• B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
• C. is one of two long, thin structures that lead to the hollow, softly lined uterus
• D. is one of two walnut-sized organs located deep inside a woman's abdomen

Correct answer: B

Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.

4. Which Apgar criterion can be more difficult to apply to newborns of all races?

• A. pink color
• B. reflex irritability
• C. limp muscle tone
• D. strong breathing

Correct answer: D

Rationale: Among the Apgar criteria, the pink color (choice A), reflex irritability (choice B), and limp muscle tone (choice C) are relatively easy to assess in newborns of all races. However, the criterion that can be more difficult to apply to newborns of all races is strong breathing (choice D). This is because evaluating the strength of a newborn's breathing can be more subjective and require careful observation. Unlike the other criteria that have more visible and objective indicators, assessing the strength of breathing might vary based on the observer's interpretation, making it more challenging to apply universally.

5. When Reggie takes his baby son, Tyson, to his workplace for the first time, Reggie's assistant abruptly picks Tyson up and walks around the office. Tyson cries and reaches out for Reggie. Tyson is expressing __________.

• A. sadness
• B. stranger anxiety
• C. separation anxiety
• D. disgust

Correct answer: B

Rationale: Tyson is experiencing stranger anxiety in this situation. Stranger anxiety is a common response in infants when they are exposed to unfamiliar people, causing distress and prompting the infant to seek comfort and familiarity, usually from their primary caregiver. This aligns with Tyson crying and reaching out for Reggie, as he is showing signs of discomfort and wariness towards the assistant, who is a stranger to him. Choice A, sadness, does not fit the scenario as Tyson's reaction is more related to fear and discomfort rather than sorrow. Choice C, separation anxiety, is not the correct answer in this context as separation anxiety pertains to distress when separated from a primary caregiver, not when encountering unfamiliar individuals. Choice D, disgust, is also not applicable as Tyson's behavior is not based on revulsion but rather on being in an unfamiliar and distressing situation.
