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.

There is experimental evidence showing that consistently being discriminated against may cause a person to ________.
- A. be happy.
- B. be more conscious.
- C. have cardiovascular reactivity.
- D. have greater intelligence and wisdom.
Correct Answer: C
Rationale: The correct answer is C: 'have cardiovascular reactivity.' Consistent discrimination can lead to increased cardiovascular reactivity, impacting heart health. Choice A ('be happy') is incorrect because discrimination typically causes distress and negative emotions. Choice B ('be more conscious') is not directly related to the impact of discrimination. Choice D ('have greater intelligence and wisdom') is also unrelated to the physiological response of cardiovascular reactivity caused by discrimination.
Freud's psychosexual stage that occurs between the ages of 3 and 5 and includes the Oedipal period is the ________ stage.
- A. genital
- B. oral
- C. phallic
- D. latency
Correct Answer: C
Rationale: Freud's psychosexual stage that occurs between the ages of 3 and 5, including the Oedipal period, is the phallic stage. During this stage, children experience the Oedipus or Electra complex, where they develop unconscious sexual desires for the opposite-sex parent and see the same-sex parent as a rival. The genital stage (Choice A) is the final stage where mature sexual interests emerge, oral (Choice B) and anal stages precede the phallic stage, and latency (Choice D) is a stage following the phallic stage characterized by a focus on developing social and cognitive skills.
If having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, the gene is a ________.
- A. risk factor
- B. necessary cause
- C. sufficient cause
- D. contributory cause
Correct Answer: B
Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.
What role does brain development play in psychopathology?
- A. Brain development has no impact on psychopathology.
- B. Brain development plays a crucial role in the onset of many mental disorders.
- C. Brain development is only linked to physical disabilities, not mental disorders.
- D. Brain development is not associated with mental health.
Correct Answer: B
Rationale: Brain development plays a crucial role in the onset of many mental disorders. It affects how the brain processes information and responds to stress, influencing the development of psychopathology. Choice A is incorrect as brain development does impact psychopathology. Choice C is incorrect as brain development is linked to mental disorders as well. Choice D is incorrect as brain development has implications for mental health.
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.
