1. During pregnancy, the placenta __________.
- A. forms in the second trimester of pregnancy
- B. encloses the developing organism in amniotic fluid
- C. contains one large vein that delivers nutrients to the embryo
- D. delivers food and oxygen to the developing organism
Correct answer: D
Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.
2. __________ parenting in particular is linked to emerging adults' psychological well-being.
- A. Overprotective
- B. Permissive
- C. Autonomy-supportive
- D. Helicopter
Correct answer: C
Rationale: Autonomy-supportive parenting, which encourages independence and decision-making skills, is positively linked to the psychological well-being of emerging adults. This style of parenting fosters resilience and self-esteem. Overprotective parenting (choice A) may hinder the development of autonomy and problem-solving abilities, leading to increased anxiety. Permissive parenting (choice B) lacks structure and limits, potentially resulting in difficulties with self-regulation. Helicopter parenting (choice D) involves excessive intervention and control, which can impede the development of self-reliance and confidence.
3. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.
- A. theory
- B. research question
- C. hypothesis
- D. research design
Correct answer: C
Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.
4. Women who __________ tend to reach menopause earlier.
- A. have had two or more children
- B. do not smoke
- C. have not borne children
- D. have borne twins
Correct answer: C
Rationale: The correct answer is C: 'have not borne children.' Women who have not borne children may experience menopause earlier due to lower levels of certain reproductive hormones. Having two or more children (choice A) is not typically associated with reaching menopause earlier. Smoking (choice B) is known to have negative effects on menopause but does not necessarily cause it to happen earlier. Borne twins (choice D) is a specific scenario and not a general factor influencing the timing of menopause.
5. Tiffany is a small-for-date baby. This means she __________.
- A. was born several weeks or more before her due date
- B. was born below her expected weight considering the length of the pregnancy
- C. will probably have much less serious problems than a preterm infant
- D. may have difficulties in infancy but will outgrow them by the preschool years
Correct answer: B
Rationale: A small-for-date baby, also known as a small-for-gestational-age (SGA) baby, is a baby who is born below their expected weight considering the length of the pregnancy. This can be due to various factors including issues with growth restriction in the womb. Being small-for-date is different from being preterm (born prematurely) and does not necessarily mean that the baby was born early. Choice A is incorrect because being small-for-date does not specifically indicate being born several weeks or more before the due date. Choice C is incorrect because being small-for-date does not guarantee fewer problems than a preterm infant, as each baby's health outcomes can vary. Choice D is incorrect because while small-for-date babies may have initial difficulties, it does not guarantee that these issues will be outgrown by the preschool years.
