1. Which of the following statements is true?

• A. Most behavioral disorders are determined exclusively by genes.
• B. Genes play a role in most mental disorders.
• C. Genes do not affect biochemical processes.
• D. The genes that will be expressed in an individual are not affected by experience.

Correct answer: B

Rationale: The correct answer is B: 'Genes play a role in most mental disorders.' This statement is true as genes do play a significant role in the development of various mental disorders. Choice A is incorrect because most behavioral disorders are influenced by a combination of genetic, environmental, and other factors, not exclusively genes. Choice C is incorrect as genes do affect biochemical processes. Choice D is incorrect because the expression of genes in an individual can be influenced by experiences and environmental factors, a concept known as gene-environment interaction.

2. Which of the following is an appropriate description of a child with conduct disorder?

• A. They may argue repeatedly with adults, ignore adult rules and requests, deliberately annoy other people, and feel much anger and resentment
• B. They have great difficulty attending to tasks, or behave overactively and impulsively, or both
• C. Marked by extreme unresponsiveness to other people, severe communication deficits, and highly rigid and repetitive behaviors, interests, and activities
• D. They are often aggressive, deliberately destroy other people's property, steal or lie, skip school, or run away from home

Correct answer: A

Rationale: The correct answer is A. Children with conduct disorder often exhibit behaviors such as arguing with adults, ignoring rules, deliberately annoying others, and displaying anger and resentment. Choice B describes symptoms more characteristic of ADHD (Attention-Deficit/Hyperactivity Disorder). Choice C describes symptoms commonly seen in individuals with autism spectrum disorders. Choice D outlines behaviors associated with oppositional defiant disorder rather than conduct disorder.

3. 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.

4. School phobia among kids may be a form of?

• A. Occurs every time when one is in a certain situation
• B. Occurs most of the time when one is in a specific situation
• C. Be unexpected
• D. Expected

Correct answer: C

Rationale: The correct answer is C: 'Be unexpected.' School phobia in children is often associated with separation anxiety disorder, leading to unexpected and intense fear or anxiety about attending school. Choices A and B are incorrect because school phobia does not necessarily occur every time or most of the time when in a specific situation; it is more about the unexpected fear related to attending school. Choice D is also incorrect because school phobia is characterized by an unexpected and overwhelming fear of school, not an expected or anticipated reaction.

5. Why is it particularly useful to study identical twins who were raised in different environments?

• A. Differences in brain function can be easily identified.
• B. Concordance rates tend to be higher.
• C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
• D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.
