1. To study the impact of biological aging on motor skills, researchers focus on __________.

Correct answer: B

Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.

2. An ovum bursts from one of a woman's two __________ and is drawn into one of two __________.

Correct answer: D

Rationale: An ovum bursts from one of a woman's two ovaries and is drawn into one of two fallopian tubes. This is a correct description of the process of ovulation and fertilization in human reproductive anatomy. The ovaries are responsible for producing and releasing eggs, while the fallopian tubes provide a pathway for the egg to travel to the uterus for potential fertilization.

3. Which of the following is a situational barrier to seeking early prenatal care?

Correct answer: B

Rationale: Difficulty arranging transportation can be a situational barrier to seeking early prenatal care because it can prevent pregnant individuals from being able to physically get to their healthcare provider for appointments. This barrier may make it challenging for individuals to access the necessary prenatal care and support for a healthy pregnancy.

4. Which statement about prenatal marijuana exposure is true?

Correct answer: A

Rationale: The correct answer is A: 'It is linked to impulsivity and overactivity.' Prenatal marijuana exposure has been associated with impulsivity and overactivity in children based on research findings. However, lasting consequences of prenatal marijuana exposure are not as well-established compared to other teratogens. Choice B is incorrect because lasting consequences are not firmly established. Choice C is incorrect because studies have shown negative effects of prenatal marijuana exposure. Choice D is incorrect as prenatal marijuana exposure is not primarily linked to physical malformations.

5. A theory of development __________.

Correct answer: B

Rationale: A theory of development describes, explains, and predicts behavior. It provides a framework for understanding how individuals grow and change over time. The purpose of a theory is not to illustrate ultimate truth or explain all aspects of human growth, but rather to help researchers and practitioners make sense of and predict human behavior. Theories are expected to be tested and refined through scientific verification. Choice A is incorrect because theories do not necessarily illustrate ultimate truth. Choice C is incorrect as theories focus on behavior and development, not all aspects of human growth. Choice D is incorrect because scientific verification is essential for theories to be valid and reliable.
