Human Growth and Development Final Exam

1. In mammals, including humans, the sense of smell __________.

A. does not become adultlike for several years
B. helps mothers and babies identify each other
C. is the least developed sense at birth
D. takes about four months to become adultlike

Correct answer: B

Rationale: The sense of smell in mammals, including humans, plays a crucial role in helping mothers and babies identify each other. This is important for initiating bonding and caregiving behaviors. Choice A is incorrect because the sense of smell is functional at birth and not entirely underdeveloped for several years. Choice C is incorrect as the sense of smell is actually well-developed at birth. Choice D is incorrect because the sense of smell is functional from birth and does not take several months to become adultlike.

2. What is the most consistent asset of resilient children?

A. a strong bond with a competent, caring adult
B. high intelligence
C. an easygoing temperament
D. an association with a rule-abiding peer

Correct answer: A

Rationale: The most consistent asset of resilient children is a strong bond with a competent, caring adult. This relationship provides crucial support, guidance, and positive role modeling, fostering resilience in children. While intelligence (choice B) can be beneficial, it is not as consistently impactful as a supportive adult bond. An easygoing temperament (choice C) may help, but it is not as universally present in resilient children. Associating with rule-abiding peers (choice D) can be helpful, but the connection with a caring adult is more significant in promoting resilience.

3. In egalitarian marriages, __________.

A. there is a clear division of roles
B. partners share power and authority
C. the husband is the head of the household
D. the wife is responsible for family economic well-being

Correct answer: B

Rationale: In egalitarian marriages, the correct answer is B - partners share power and authority. This type of marriage promotes equality and balance, where both spouses have an equal say in decision-making and share responsibilities. Choice A is incorrect because egalitarian marriages aim to reduce traditional role divisions. Choice C is incorrect as it suggests a patriarchal structure, which is contrary to the principles of egalitarianism. Choice D is incorrect as it assigns a specific financial role based on gender, which goes against the idea of equal sharing in all aspects of the marriage.

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.
