1. Which of the following explanations for the relationship between SES and abnormal behavior is not supported by the existing data?

• A. Low SES may cause abnormal behavior.
• B. Abnormal behavior is more likely to go untreated in those of low SES.
• C. Recovery from loss of a job may be more difficult for those exhibiting signs of mental illness.
• D. High SES may cause abnormal behavior.

Correct answer: D

Rationale: The correct answer is D because high SES as a cause for abnormal behavior is not supported by existing data. Abnormal behavior is often associated with factors like stress, trauma, genetics, or environmental influences. High SES is not a known cause of abnormal behavior. Choices A, B, and C are more plausible explanations: Low SES may lead to limited access to mental health care, untreated abnormal behavior due to financial constraints, and difficulties in coping with mental health issues after job loss, respectively.

2. If a pair of monozygotic twins raised in the same environment end up being different from one another (e.g., interests, hobbies, etc.), it is highly likely due to:

• A. Cephalocaudal pattern
• B. Proximodistal pattern
• C. Cephamodistal pattern
• D. Gene-environment correlation

Correct answer: B

Rationale: The correct answer is B: Proximodistal pattern. Differences between monozygotic twins raised in the same environment are likely due to non-shared environmental influences, which lead to differences in interests, hobbies, and other individual characteristics. Choices A, C, and D are incorrect. Cephalocaudal pattern refers to the principle of development from head to toe, not relevant in explaining differences between twins. Cephamodistal pattern is not a recognized developmental term. Gene-environment correlation does not directly explain the differences between identical twins raised in the same environment.

3. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.

4. 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: Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This is the correct answer as it accurately describes the typical chromosome count in human cells. Choice B is incorrect because it mentions 'twenty-one trisomy chromosome pairs,' which is not characteristic of normal cells. Choice C is incorrect as it suggests having 'two trisomy chromosome pairs,' which is abnormal. Choice D is incorrect as it states 'twenty-three chromosome pairs,' which is not the standard count in normal human cells.

5. When Ryan was born, the hospital assessed his health with the Apgar scale, and the score was 5. What does this mean with respect to his breathing pattern?

• A. He was not in danger
• B. He needed help in establishing a breathing pattern
• C. He was in excellent condition
• D. He was in critical condition

Correct answer: B

Rationale: An Apgar score of 5 suggests that Ryan needed help establishing a regular breathing pattern after birth. Choice A is incorrect because a score of 5 indicates the need for assistance. Choice C is incorrect as an Apgar score of 5 does not reflect excellent condition. Choice D is incorrect as it signifies a critical condition, which is not the case with an Apgar score of 5.
