1. 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.

2. Undercontrolled behavior tends to be seen in American children, whereas overcontrolled behavior is seen in Thai children.

• A. Aggressive behavior; calm behavior
• B. Overcontrolled behavior; undercontrolled behavior
• C. Undercontrolled behavior; overcontrolled behavior
• D. Equal behavioral traits in both cultures.

Correct answer: C

Rationale: The correct answer is C: 'Undercontrolled behavior; overcontrolled behavior.' The question highlights a cultural difference in behavior tendencies between American and Thai children. American children are usually characterized by undercontrolled behavior, while Thai children tend to exhibit overcontrolled behavior. Choice A (Aggressive behavior; calm behavior) is incorrect as the question does not mention aggressive or calm behavior as the contrasting traits between the two groups. Choice B (Overcontrolled behavior; undercontrolled behavior) is incorrect because the described behavior patterns are reversed based on the question's context. Choice D (Equal behavioral traits in both cultures) is incorrect as the question explicitly states differing behavior patterns in American and Thai children.

3. Albert has brown eyes, even though one of his biological parents has blue eyes. Genes for blue eyes are part of Albert's ___.

• A. Phenotype
• B. Zygote
• C. Genotype
• D. Environment

Correct answer: C

Rationale: Albert's genotype refers to the genetic makeup inherited from his parents, which includes the genes for blue eyes. The phenotype, on the other hand, is the observable trait, in this case, brown eyes. Therefore, the correct answer is C. Choice A (Phenotype) is incorrect as it refers to the observable characteristics, not the genetic information. Choice B (Zygote) is incorrect as it refers to the initial stage of a developing organism. Choice D (Environment) is incorrect as it does not directly determine eye color.

4. In a breech presentation, how is the infant positioned for delivery?

• A. Is too large to be delivered vaginally.
• B. Is delivered feet or bottom first.
• C. Is delivered head first.
• D. Appears face down.

Correct answer: B

Rationale: In a breech presentation, the infant is positioned to be delivered feet or bottom first. This is because the baby's pelvis or feet enter the birth canal before the head. Therefore, choice B is correct. Choices A, C, and D are incorrect because a breech presentation specifically refers to the baby being positioned feet or bottom first, not head first, face down, or being too large for vaginal delivery.

5. 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.
