Human Growth and Development Exam Questions
1. The force of blood flowing through the __________ keeps it firm.
- A. amnion
- B. umbilical cord
- C. yolk sac
- D. embryonic disk
Correct answer: B
Rationale: The force of blood flowing through the umbilical cord keeps it firm. The umbilical cord is the connection between the placenta and the fetus, providing essential nutrients and oxygen to the developing baby. Blood flow through the umbilical cord helps maintain its structure and function throughout the prenatal period. Choices A, C, and D are incorrect as they do not play a role in providing nutrients and oxygen to the developing baby or in maintaining its firmness.
2. Dana is pregnant with her first child and wonders how much weight she should gain during the pregnancy. You should recommend a healthy diet that results in a weight gain of __________ pounds.
- A. 10 to 15
- B. 15 to 20
- C. 25 to 30
- D. 35 to 40
Correct answer: C
Rationale: The recommended weight gain during pregnancy depends on the pre-pregnancy weight of the mother. For a woman with a normal pre-pregnancy BMI, the recommended weight gain is typically between 25 to 30 pounds. This range is considered healthy to support the growth and development of the baby while also maintaining the mother's health. Choices A, B, and D are incorrect as they represent weight gain ranges that are either too low or too high for a woman with a normal pre-pregnancy BMI, which could pose health risks for both the mother and the baby. It is crucial to adhere to healthcare professionals' guidelines to ensure a healthy pregnancy and birth outcome.
3. During prenatal development, the ectoderm becomes the __________.
- A. muscles and skeleton
- B. nervous system and skin
- C. circulatory system and other internal organs
- D. digestive system, lungs, urinary tract, and glands
Correct answer: B
Rationale: The correct answer is B: nervous system and skin. The nervous system, which includes the brain, spinal cord, and nerves, as well as the skin, develop from the ectoderm layer of cells during prenatal development. Choice A is incorrect because muscles and skeleton develop from mesoderm. Choice C is incorrect because the circulatory system and other internal organs develop from mesoderm and endoderm. Choice D is incorrect because the digestive system, lungs, urinary tract, and glands develop from endoderm.
4. Ethnographies reveal that immigrant parents view __________ as the surest way to improve life chances.
- A. learning English
- B. education
- C. close ties to an ethnic community
- D. moving into an urban area
Correct answer: B
Rationale: Ethnographies reveal that immigrant parents prioritize education as the surest way to improve life chances for their children. While learning English is important for integration, education is considered the key for better opportunities and success in the long term. Close ties to an ethnic community can provide support but may not directly lead to improved life chances. Moving into an urban area is not highlighted in the context of immigrant parents' views on improving life chances through their children's development.
5. __________, especially, are more insistent that __________ conform to gender roles.
- A. Mothers; boys
- B. Mothers; girls
- C. Fathers; girls
- D. Fathers; boys
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.
