Normal human cells have ________.
- A. twenty-two chromosome pairs and one pair of sex chromosomes.
- B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
- C. twenty-one chromosome pairs and two trisomy chromosome pairs.
- D. twenty-three chromosome pairs.
Correct Answer: A
Rationale: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.

Which of the following perspectives focuses on social determinants of behavior?
- A. The attachment perspective
- B. The interpersonal perspective
- C. The humanistic perspective
- D. The existential perspective
Correct Answer: B
Rationale: The interpersonal perspective focuses on social determinants of behavior, emphasizing the impact of social interactions, relationships, and communication on an individual's behavior. This perspective looks at how people's behavior is influenced by their interactions with others and the social environment. Choices A, C, and D are incorrect because they do not primarily focus on social determinants of behavior. The attachment perspective is concerned with emotional bonds between individuals, the humanistic perspective emphasizes personal growth and self-fulfillment, and the existential perspective focuses on individual freedom and responsibility in creating meaning in life.
What is a culture-bound disorder?
- A. It is a disorder seen universally across all cultures.
- B. It is a disorder that exists in one culture but is completely absent in others.
- C. It is a disorder that only affects children.
- D. It is a disorder found exclusively within certain age groups.
Correct Answer: B
Rationale: A culture-bound disorder is a condition that is specific to a particular culture or group of cultures and is not universally recognized or experienced across different cultures. Choice A is incorrect because a culture-bound disorder is not seen universally across all cultures. Choice C is incorrect because it does not necessarily have to only affect children. Choice D is incorrect as a culture-bound disorder is not exclusively found within certain age groups, but rather tied to specific cultures.
A major factor associated with a child's rejection by peers is ________.
- A. Overly aggressive behavior.
- B. Being too intelligent.
- C. Socioeconomic background.
- D. A lack of empathy.
Correct Answer: A
Rationale: Overly aggressive behavior is often a major factor in a child's rejection by peers. Children who display overly aggressive behavior may intimidate or harm their peers, leading to social rejection. Being too intelligent or having a different socioeconomic background are not typically primary reasons for peer rejection. While empathy is important for healthy social interactions, a lack of empathy, on its own, is less likely to be a primary factor in peer rejection compared to overly aggressive behavior.
The genetic influences that determine behavior may never be fully understood due to ________
- A. the ease of researching to differentiate between the effects of the environment and the effects of genes.
- B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
- C. the tendency to rely on twin studies in genetic research.
- D. our significant understanding of how genes impact brain chemistry.
Correct Answer: B
Rationale: The correct answer is B because most behaviors are influenced by a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.
Neural plasticity is ________.
- A. the process by which neurotransmitters are broken down in the brain.
- B. the flexibility of the brain-existing neural circuits can change or new ones can be made.
- C. strong evidence of brain damage, leading to the development of a mental disorder.
- D. the best indicator of temperament and its effect on the personality development of a child.
Correct Answer: B
Rationale: Neural plasticity refers to the brain's flexibility to change existing neural circuits or create new ones. Choice A is incorrect as it describes neurotransmitter breakdown, not neural plasticity. Choice C is incorrect because neural plasticity does not necessarily indicate brain damage leading to mental disorders. Choice D is incorrect because neural plasticity is not specifically related to temperament or personality development in children.
