Human Growth and Development Exam Questions

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

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. Students who are foreign-born or first-generation Americans _______ than students of native-born parents.

Correct answer: C

Rationale: According to the information provided in the text box 'CULTURAL INFLUENCES: Immigrant Youths: Adapting to a New Land' on page 32, students who are foreign-born or first-generation Americans often achieve in school as well as or better than students of native-born parents. This implies that they excel academically despite facing challenges related to cultural adaptation and assimilation. Choices A, B, and D are incorrect because the provided information specifically highlights the academic achievement of foreign-born or first-generation American students compared to students of native-born parents, not their likelihood of committing delinquent acts, obesity rates, or self-esteem levels.

3. Newborn Mariana, who reacts strongly to unpleasant stimuli, is __________.

Correct answer: B

Rationale: Newborn Mariana, who reacts strongly to unpleasant stimuli, is described as susceptible to colic. Colic is often characterized by excessive crying and fussiness in newborn babies, which can be challenging to console. This description suggests that Mariana's strong reactions to unpleasant stimuli may make her more prone to colic. Choices A, C, and D are incorrect because the strong reactions to unpleasant stimuli do not imply being easy to console, affect REM sleep, or responsiveness to swaddling.

4. Men with even tiny amounts of dioxin in their bloodstream father __________.

Correct answer: A

Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.

5. The third stage of labor lasts about __________.

Correct answer: A

Rationale: The correct answer is A: 5 to 10 minutes. The third stage of labor typically lasts about 5 to 10 minutes. This stage begins after the baby is born and ends when the placenta is delivered. It is the shortest stage of labor compared to the first and second stages. Choice B, 20 to 50 minutes, is incorrect as it is too long for the duration of the third stage. Choice C, 4 to 6 hours, and Choice D, 12 to 14 hours, are also incorrect as they are significantly longer than the actual duration of the third stage of labor.
