1. What is a person's total genetic endowment?

• A. Phenotype
• B. Genotype
• C. Chromosomes
• D. DNA

Correct answer: B

Rationale: The correct answer is B: Genotype. A genotype refers to a person's total genetic endowment, representing the specific genetic makeup inherited from their parents. This includes all the genes and genetic information contained in an individual's DNA. Choices A, C, and D are incorrect because: A) Phenotype refers to the observable characteristics resulting from the interaction of genetics and the environment; C) Chromosomes are physical structures that contain genes, not the total genetic endowment itself; D) DNA carries genetic information but is just one component of an individual's total genetic endowment.

2. What is the result when a single zygote separates into two parts, each developing into a separate individual?

• A. Dizygotic twin
• B. Monozygotic twin
• C. Fraternal twin
• D. Nonidentical twin

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

3. Sandy took part in the April 2013 Boston Marathon, where two bombs were detonated near the finish line, killing three spectators. For approximately 2 weeks after the marathon, Sandy was unable to sleep or concentrate and often found herself reliving the moment she heard the bombs explode. What disorder might Sandy be diagnosed with?

• A. Posttraumatic stress disorder
• B. Phobic disorder
• C. Panic disorder
• D. Acute stress disorder

Correct answer: A

Rationale: Sandy might be diagnosed with posttraumatic stress disorder (PTSD). PTSD typically develops after exposure to a traumatic event and is characterized by symptoms such as re-experiencing the event, avoidance of reminders of the event, negative changes in thoughts and mood, and heightened reactivity. While acute stress disorder can occur shortly after a traumatic event, the duration of symptoms in the scenario suggests a more prolonged impact, aligning with PTSD. Phobic disorder and panic disorder are not as closely related to the described symptoms as PTSD.

4. Define resilience and explain its significance in mental health.

• A. Resilience refers to the ability to avoid all mental health issues despite severe stress.
• B. Resilience is the ability to adapt successfully to even very difficult circumstances.
• C. Resilience is the tendency to be unaffected by any form of stress or adversity.
• D. Resilience is the ability to avoid stress by avoiding challenges.

Correct answer: B

Rationale: The correct definition of resilience is the ability to adapt successfully to difficult circumstances, not avoiding stress entirely. Resilience is significant in mental health as it helps individuals overcome adversity rather than avoiding it. Choice A is incorrect as resilience doesn't mean avoiding all mental health issues but rather dealing with stress effectively. Choice C is incorrect as resilience involves facing and overcoming stress, not being unaffected by it. Choice D is incorrect as resilience involves facing challenges and stress, not avoiding them altogether.

5. Barney helps his younger brother, who has just learned to cycle on his own, to navigate narrow roads and sharp turns. Vygotsky will refer to this as ________?

• A. Microsystem
• B. Macrosystem
• C. Mesosystem
• D. Exosystem

Correct answer: C

Rationale: In this scenario, where Barney is assisting his younger brother in navigating narrow roads and sharp turns, Vygotsky would refer to this as an example of the 'mesosystem.' The mesosystem involves the interactions between different systems in a child's environment, such as family and peers. Choices A, B, and D are incorrect: A) Microsystem refers to the immediate environment where the child lives, like home and school; B) Macrosystem encompasses the larger cultural context; D) Exosystem involves external settings that indirectly influence the child.
