1. __________ emerges early prenatally and is well-developed at birth.

• A. Visual acuity
• B. Color vision
• C. Depth perception
• D. Sensitivity to touch

Correct answer: D

Rationale: Sensitivity to touch emerges early prenatally and is well-developed at birth. Newborn babies have a well-developed sense of touch, which is crucial for bonding with their caregivers and exploring their environment. This sensitivity to touch helps babies respond to comforting sensations such as gentle strokes and cuddles. Visual acuity, color vision, and depth perception are sensory capabilities that develop and mature after birth, not prenatally. While important for interacting with the environment, they are not as well-developed at birth as sensitivity to touch.

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

• A. nearly twice as many girls as boys
• B. nearly three times as many boys as girls
• C. more twins and triplets than unaffected men
• D. fewer children than unaffected men

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.

4. What did Ivan Pavlov discover?

• A. observational learning
• B. classical conditioning
• C. the ego's positive contributions to development
• D. the clinical method

Correct answer: B

Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.

5. The immune response is the combined work of specialized cells that neutralize or destroy __________ in the body.

• A. T cells
• B. B cells
• C. telomeres
• D. antigens

Correct answer: D

Rationale: The correct answer is D, antigens. Antigens are substances recognized by the immune system as foreign, triggering an immune response to neutralize or destroy them. In this context, T cells and B cells are specialized cells of the immune system that respond to antigens, but they are not the substances being neutralized or destroyed. Telomeres, on the other hand, are protective structures at the end of chromosomes and are not targeted for neutralization or destruction by the immune system.
