Human Growth and Development Clep Practice Exam

Correct Answer: D

Rationale: The correct answer is 'Birth weight.' Birth weight is a crucial indicator of an infant's chances of survival and well-being. Low birth weight is associated with various health risks and developmental challenges. Birth length (choice A) is not as significant in predicting infant outcomes as birth weight. The Combined Apgar score (choice B) is a measure of the newborn's health status at birth, not a predictor of long-term survival and development. Delivery date (choice C) is important for determining gestational age but is not as directly related to infant survival and healthy development as birth weight.

Correct Answer: B

Rationale: Basic emotions like happiness, sadness, and anger are universal across humans, meaning they are experienced by people worldwide regardless of cultural differences. These emotions are not limited to a specific group of individuals or exclusive to humans; they are observed in various species. Choice A is incorrect because basic emotions actually appear early in life, not specifically in the middle of the second year. Choice C is incorrect as basic emotions are not exclusive to humans but are observed in other animals as well. Choice D is incorrect because basic emotions do not necessarily involve injury to our sense of self, but rather represent fundamental and instinctual feelings that are part of human nature.

Correct Answer: B

Rationale: The correct answer is B. Fraternal twins are no more alike than ordinary siblings because they share about 50% of their genes, just like other siblings. Choice A is incorrect as fraternal twins are not genetically identical. Choice C is incorrect as fraternal twins are actually the most common type of multiple offspring. Choice D is incorrect as the likelihood of fraternal twins is not affected by the number of births a mother has had.

Correct Answer: A

Rationale: Physical activity is known to have a positive impact on mental health by reducing symptoms of anxiety and depression. Choice B is incorrect because physical activity generally improves both mood and alertness. Choice C is incorrect as physical activity tends to increase mood, alertness, and energy levels. Choice D is incorrect as physical activity actually increases neural activity in the cerebral cortex, which is associated with improved cognitive function and mental well-being.

Correct Answer: B

Rationale: According to Erikson's theory of psychosocial development, despair is the stage that aging adults face when they reflect on their life and feel they have not achieved their goals, with little time left to correct their mistakes. Mistrust (choice A) is associated with infancy, stagnation (choice C) with middle adulthood, and isolation (choice D) with young adulthood, and are not relevant to the described scenario of aging adults reflecting on their life decisions.
