1. Vygotsky's emphasis on culture and social experience led him to __________.

• A. understand the interaction between biological factors and social influences in cognitive development
• B. overemphasize the role of heredity in cognitive change
• C. emphasize children's independent efforts to make sense of their world
• D. place too much emphasis on children's capacity to shape their own development

Correct answer: A

Rationale: Vygotsky's emphasis on culture and social experience did not lead him to neglect the biological side of development. Instead, he believed that biological factors and social influences interact to shape cognitive development. Choice A is correct because it reflects Vygotsky's view that biological factors and social experiences work together in cognitive development. Choices B, C, and D are incorrect as Vygotsky's emphasis was not on overemphasizing heredity, focusing solely on independent efforts of children, or placing too much emphasis on children's capacity to shape their own development.

2. When the blastocyst burrows deep into the uterine lining, __________.

• A. implantation occurs
• B. pregnancy does not occur
• C. it stops growing
• D. the cells of the zygote first duplicate

Correct answer: A

Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.

3. Prenatally malnourished babies frequently __________.

• A. reject breast milk
• B. have enlarged hearts
• C. catch respiratory illnesses
• D. have a higher-than-average birth weight

Correct answer: C

Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.

4. 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.

5. In females, the twenty-third pair of chromosomes is labeled as __________.

• A. an autosome
• B. dizygotic
• C. XX
• D. XY

Correct answer: C

Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.
