1. During the second trimester, a white, cheeselike substance called __________ emerges on the skin.

• A. lanugo
• B. corpus luteum
• C. vernix
• D. chorion

Correct answer: C

Rationale: During the second trimester of pregnancy, a white, cheeselike substance called vernix emerges on the skin of the developing fetus. Vernix is a protective layer that helps prevent the skin from becoming waterlogged during the time in the amniotic fluid. Choice A, lanugo, is incorrect as lanugo refers to the fine, soft hair that covers the body of a fetus. Choice B, corpus luteum, is incorrect as it is a temporary endocrine structure involved in the menstrual cycle. Choice D, chorion, is incorrect as it is one of the membranes that surround the embryo and later the fetus.

2. What is strongly associated with healthy eating in teenagers?

• A. Vitamin supplementation
• B. Number of hours of sleep
• C. Dieting in adolescence
• D. Frequency of family meals

Correct answer: D

Rationale: The frequency of family meals is strongly associated with healthy eating in teenagers. Research indicates that regular family meals provide structure, promote positive eating behaviors, and offer opportunities for modeling healthy food choices. Vitamin supplementation (Choice A) may be beneficial but is not as strongly linked to healthy eating habits as family meal frequency. The number of hours of sleep (Choice B) is important for overall health but is not as directly associated with healthy eating behaviors in teenagers. Dieting in adolescence (Choice C) can sometimes lead to unhealthy eating patterns and is not necessarily linked to consistently healthy food choices.

3. Maternal high blood glucose _________.

• A. can cause Rh factor incompatibility
• B. is linked to poorer memory in early childhood
• C. is linked to low birth weight
• D. can cause the mother's blood pressure to increase sharply

Correct answer: B

Rationale: Maternal high blood glucose is linked to poorer memory in early childhood. Research has shown that exposure to high levels of maternal blood glucose during pregnancy may negatively impact a child's memory development in early childhood. This highlights the importance of managing blood glucose levels during pregnancy for the health and development of the child. Choices A, C, and D are incorrect because they do not reflect the established link between maternal high blood glucose and poorer memory in early childhood. Rh factor incompatibility is related to blood type differences between the mother and the fetus, low birth weight can be linked to various factors other than maternal blood glucose, and sharp increases in the mother's blood pressure are not directly associated with maternal high blood glucose.

4. A major limitation of systematic observation is that it __________.

• A. provides little information on how participants actually behave
• B. tells investigators little about the reasoning behind responses and behaviors
• C. underestimates the capacities of individuals who have difficulty putting their thoughts into words
• D. ignores participants with poor memories, who may have trouble recalling exactly what happened

Correct answer: B

Rationale: A major limitation of systematic observation is that it tells investigators little about the reasoning behind responses and behaviors. Systematic observation focuses more on recording observable behaviors rather than delving into the underlying reasons or thought processes driving those behaviors. Choices A, C, and D are incorrect because systematic observation can indeed provide detailed information on how participants actually behave, it doesn't necessarily underestimate the capacities of individuals who struggle with verbal expression, and it doesn't solely ignore participants with poor memories as it can capture behavior in real-time regardless of memory recall.

5. When __________, newborn Takeo's toes should fan out and curl as his foot twists in.

• A. a bright light shines in his eyes
• B. his bare foot touches a flat surface
• C. his cheek is stroked near the corner of his mouth
• D. the sole of his foot is stroked from toe to heel

Correct answer: D

Rationale: The correct answer is D because the description of the twisting and fanning out of newborn Takeo's toes suggests the Babinski reflex, which is typically elicited by stroking the sole of the foot from toe to heel. The Babinski reflex is a normal response in newborns and indicates proper neurological development. Choices A, B, and C are incorrect as they do not elicit the specific response described in the question.
