1. __________ 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.

2. Which mother is most likely to have had inadequate prenatal care?

• A. Lupe, age 25
• B. Marissa, age 32
• C. Rotunda, age 16
• D. Janette, age 40

Correct answer: C

Rationale: Rotunda, age 16, is the most likely to have had inadequate prenatal care due to her young age and possibly limited access to healthcare resources and support. Adolescents are at higher risk for inadequate prenatal care compared to older mothers due to various factors such as lack of awareness, financial constraints, and inconsistent health behaviors. Young mothers may face challenges in seeking proper prenatal care due to reasons like lack of knowledge, fear of judgment, or limited financial means. Older mothers like Lupe, Marissa, and Janette are less likely to have inadequate prenatal care compared to a younger mother like Rotunda, as they may have more access to resources, experience, and support systems.

3. Recent evidence suggests that paternal alcohol use around the time of conception __________.

• A. can alter gene expression
• B. can cause fetal alcohol syndrome
• C. is linked to blood vessel abnormalities
• D. has no negative effect on the developing organism

Correct answer: A

Rationale: Recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression. This means that paternal alcohol consumption can potentially impact the genes and genetic materials passed on to offspring, affecting their development and health. Choice B is incorrect because fetal alcohol syndrome is typically associated with maternal alcohol consumption during pregnancy, not paternal alcohol use around conception. Choice C is incorrect as there is no direct link between paternal alcohol use and blood vessel abnormalities. Choice D is incorrect as paternal alcohol use can indeed have negative effects on the developing organism, particularly through altering gene expression.

4. The concept of ________ means that because of their genetic makeup, individuals differ in their responsiveness to qualities of the environment.

• A. gene-environment interaction
• B. niche-picking
• C. passive correlation
• D. evocative correlation

Correct answer: A

Rationale: The correct answer is A, gene-environment interaction. This concept highlights that genetic factors play a role in how individuals react to environmental factors. Niche-picking (choice B) refers to the tendency of individuals to select environments that complement their genetic predispositions, not the inherent genetic differences in responsiveness. Passive correlation (choice C) involves the association between the genetic makeup of parents and the environment they provide for their children, not individual differences in responsiveness. Evocative correlation (choice D) relates to the idea that an individual's genetic traits can elicit certain responses from others in the environment, rather than individual differences in responsiveness.

5. Spatial skills __________.

• A. increase exponentially in early childhood
• B. support children's improved executive function
• C. develop gradually over childhood and adolescence
• D. are typically housed in the left hemisphere

Correct answer: C

Rationale: Spatial skills develop gradually over childhood and adolescence, reflecting the increasing complexity of these abilities. Choice A is incorrect because spatial skills do not increase exponentially in early childhood but rather develop steadily. Choice B is incorrect as spatial skills are not directly linked to executive function. Choice D is incorrect because spatial skills are not typically housed in a specific hemisphere but involve a network of brain regions.
