Human Growth and Development Final Exam Answers

1. During which period does the germinal period occur?

Correct answer: C

Rationale: The germinal period lasts about two weeks and occurs during the first two weeks of pregnancy. This is the time when the fertilized egg implants into the uterus and begins to divide rapidly. It is followed by the embryonic period, which lasts from about week 3 to week 8 of pregnancy. Choice A is incorrect because the germinal period happens in the early stages of pregnancy, not the second trimester. Choice B is incorrect because the germinal period typically lasts about two weeks, not six. Choice D is incorrect because the germinal period is an early stage of pregnancy and not the final period of a 38-week pregnancy.

2. Piaget's _________ stage is the most complex period of development.

Correct answer: D

Rationale: The formal operational stage in Piaget's theory is characterized by abstract reasoning, hypothetical thinking, and logical reasoning. This stage represents the most complex period of cognitive development according to Piaget. Choices A, B, and C refer to earlier stages in Piaget's theory and do not involve the level of abstract thinking and logical reasoning seen in the formal operational stage.

3. __________, especially, are more insistent that __________ conform to gender roles.

Correct answer: D

Rationale: The correct answer is D: 'Fathers; boys.' The extract provided indicates that fathers are particularly insistent that boys adhere to traditional gender roles, emphasizing masculinity. This is a common stereotype where fathers often push their sons to conform to societal expectations of masculinity. Choices A and B are incorrect because the extract specifies fathers, not mothers. Choice C is incorrect as it pairs fathers with girls, which is not supported by the provided information.

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

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.

5. During the second month of pregnancy, __________.

Correct answer: C

Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
