Growth and Development Exam

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

A. ovaries; testes
B. fallopian tubes; ovaries
C. corpus luteum; fallopian tubes
D. ovaries; fallopian tubes Answer: D Page Ref: 76 Skill Level: Remember Topic: Prenatal Development Difficulty Level: Easy

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.

2. Unlike adults, newborn babies __________.

A. have a limited sense of smell
B. see nearby objects most clearly
C. prefer unfamiliar voices to familiar ones
D. see unclearly across a wide range of distances

Correct answer: B

Rationale: Unlike adults, newborn babies see nearby objects most clearly. This is due to the fact that newborns have a limited ability to focus their eyes on objects that are farther away. Their visual acuity is not fully developed at birth, leading to clearer vision of objects situated at a close distance. Choice A is incorrect because newborn babies have a well-developed sense of smell. Choice C is incorrect as newborns typically show a preference for familiar voices, such as their mother's voice. Choice D is incorrect as newborns do not see unclearly across a wide range of distances; rather, their vision is clearer for nearby objects.

3. During prenatal development, the ectoderm folds over to form the __________, or primitive spinal cord.

A. mesoderm; neuron tract
B. neural tube
C. endoderm; neural tube
D. neuron tract

Correct answer: B

Rationale: The correct answer is B. During prenatal development, the ectoderm folds over to form the neural tube, which eventually develops into the brain and spinal cord. The neural tube is the precursor to the central nervous system, including the primitive spinal cord. Choices A, C, and D are incorrect because the mesoderm does not form the neural tube, the endoderm is not involved in the formation of the central nervous system, and neuron tract is not the structure that forms the primitive spinal cord.

4. Which statement about the human immunodeficiency virus (HIV) is true?

A. About 30 percent of all new HIV infections affect women.
B. In South Africa, 30 percent of all pregnant women are HIV-positive.
C. About 30 percent of new HIV infections occur in developing countries.
D. Untreated HIV-infected mothers pass the virus to the fetus 30 percent of the time.

Correct answer: B

Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.

5. At Kohlberg's Stage __________, individuals can imagine alternatives to their own social order, and they emphasize fair procedures for interpreting and changing the law.

A. 3, the 'good boy/good girl' orientation
B. 4, the social-order-maintaining orientation
C. 5, the social contract orientation
D. 6, the universal ethical principle orientation

Correct answer: C

Rationale: The correct answer is C: '5, the social contract orientation.' At Kohlberg's Stage 5, individuals begin to question their own social order and focus on principles of justice and fairness. This stage emphasizes the importance of social contracts and agreements based on mutual benefit. Choice A is incorrect as the 'good boy/good girl' orientation is characteristic of Stage 3. Choice B, the social-order-maintaining orientation, does not align with the description provided in the question. Choice D, the universal ethical principle orientation, is associated with Stage 6, where individuals act based on self-chosen ethical principles.
