1. During Irina's first week of pregnancy, __________.

• A. heart muscles begin to develop
• B. the zygote multiplies and forms a blastocyst
• C. a primitive brain and spinal cord appear
• D. the embryo can move

Correct answer: B

Rationale: During the first week of pregnancy, the zygote (fertilized egg) undergoes rapid cell divisions and forms a blastocyst. This is a crucial stage where the cells differentiate and specialize, setting the foundation for the development of the embryo. It is during this time that the zygote implants itself into the uterine wall, initiating the process of pregnancy. Choices A, C, and D are incorrect because during the first week of pregnancy, the focus is on the initial development and multiplication of the zygote, not on the development of heart muscles, a primitive brain and spinal cord, or the embryo's ability to move.

2. 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.

3. Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress __________.

• A. nature over nurture
• B. changes in thinking
• C. unconscious motives and drives
• D. the effects of punishment and reinforcement on behavior Answer: B Page Ref: 26 Skill Level: Understand development. Topic: Comparing and Evaluating Theories Difficulty Level: Difficult

Correct answer: B

Rationale: Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress changes in thinking. These theories focus on how cognitive abilities develop over time, emphasizing the growth and transformation of thinking processes rather than static traits or characteristics.

4. __________ supplementation early in pregnancy reduces the risk of abnormalities of the neural tube, the circulatory system, and the urinary tract.

• A. Vitamin A
• B. Folic acid
• C. Vitamin D
• D. Vitamin C

Correct answer: B

Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.

5. Dr. Wu observes children’s responses to bullying by watching them play in a park. This is an example of a(n) __________.

• A. ethnographic study
• B. naturalistic observation
• C. structured observation
• D. clinical interview Answer: B Page Ref: 28 Skill Level: Apply Topic: Studying Development Difficulty Level: Moderate

Correct answer: B

Rationale: Dr. Wu's observation of children's responses to bullying by watching them play in a park is an example of naturalistic observation. Naturalistic observation involves observing behavior in a natural setting without any manipulation or intervention. Dr. Wu is simply observing the children's behavior in a real-world setting to gain insights into how they respond to bullying, making it a naturalistic observation.
