1. In the __________ period, teratogens rarely have any impact.

• A. germinal
• B. embryonic
• C. fetal
• D. prenatal

Correct answer: A

Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.

2. In ecological systems theory, how does Toby's move just before entering fourth grade represent a significant change in his life?

• A. Microsystem
• B. Mesosystem
• C. Exosystem
• D. Chronosystem

Correct answer: D

Rationale: In ecological systems theory, the chronosystem refers to the dimension of time and how events and transitions over time can influence an individual's development. Toby's move just before entering fourth grade represents a significant change in his life that falls under the chronosystem. The microsystem involves the immediate environments and relationships that directly influence an individual, the mesosystem relates to connections between these environments, and the exosystem includes external settings that indirectly influence the individual, such as parents' workplaces. Therefore, Toby's move best exemplifies a change in the chronosystem due to the temporal influence on his development.

3. __________ may heighten the effects of a high-fat diet.

• A. Sex hormones
• B. Over-the-counter medications
• C. Free radicals
• D. Low body weight

Correct answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.

4. Natural childbirth experts Grantly Dick-Read and Fernand Lamaze recognized that cultural attitudes about childbirth had __________.

• A. taught women to fear the birth experience
• B. helped women develop breathing techniques to lessen the pain of labor
• C. taught women that medical intervention was unnecessary in childbirth
• D. helped women focus on child rearing rather than childbirth

Correct answer: A

Rationale: Natural childbirth experts Grantly Dick-Read and Fernand Lamaze recognized that cultural attitudes about childbirth had taught women to fear the birth experience. They believed that this fear contributed to increased pain during labor and advocated for methods to reduce fear and promote relaxation during childbirth. Choice B is incorrect as the focus is on fear, not on techniques to lessen pain. Choice C is incorrect as the experts did not advocate against medical intervention but rather against unnecessary fear. Choice D is incorrect as the experts aimed to change attitudes towards childbirth, not redirect focus to child rearing.

5. In a longitudinal design, participants are studied repeatedly at different ages, and changes are noted as they get older.

• A. cross-sectional
• B. experimental
• C. longitudinal
• D. correlational

Correct answer: C

Rationale: The correct answer is C: longitudinal. In a longitudinal design, participants are followed and studied over an extended period, allowing researchers to observe changes and continuity in development as individuals age. This design is crucial for understanding how individuals grow and change over time. Cross-sectional studies (Choice A) involve comparing different groups at the same time point, while experimental studies (Choice B) involve manipulating variables to observe their effects. Correlational studies (Choice D) examine relationships between variables but do not involve studying participants over time.
