1. 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.

2. Charles has suffered from schizophrenia for many years and now resides in a group treatment facility. One day a nurse approaches him and quietly tells him that his sister, who has been fighting cancer for many months, died that morning. Charles has no appreciable facial reaction and in a very monotone voice says, 'okay.' The nurse is not surprised by Charles's lack of response to the awful news because she knows that _________ is one symptom often seen in those suffering from schizophrenia?

• A. Clang associations
• B. Echolalia
• C. Blunted affect
• D. Perseveration

Correct answer: C

Rationale: In individuals with schizophrenia, blunted affect, or reduced emotional expression, is a common symptom. In this scenario, Charles's lack of emotional response upon hearing about his sister's death aligns with the characteristic of blunted affect. This symptom can manifest as a limited range of facial expressions, monotone voice, and reduced display of emotions. Choice A, 'Clang associations,' refers to a thought disorder characterized by the use of words that sound alike but are not logically connected. Choice B, 'Echolalia,' is the repetition of words spoken by others. Choice D, 'Perseveration,' is the persistent repetition of a response or behavior even when it is no longer appropriate.

3. Which neurotransmitter is reduced in both the manic and depressive phases of bipolar disorder?

• A. Acetylcholine
• B. Dopamine
• C. Norepinephrine
• D. Serotonin

Correct answer: D

Rationale: The correct answer is D, Serotonin. Serotonin levels are reduced during both the manic and depressive phases of bipolar disorder. Acetylcholine (choice A) is not typically linked to bipolar disorder. Dopamine (choice B) and norepinephrine (choice C) are more commonly associated with conditions like schizophrenia and depression, respectively, rather than bipolar disorder. Therefore, they are not the neurotransmitters reduced in both manic and depressive phases of bipolar disorder.

4. How is binge-eating disorder different from bulimia?

• A. Typically eat much smaller portions before purging the food.
• B. Do not typically purge the food they eat.
• C. Only purge their food after several binge sessions.
• D. Often resort to anorexic methods to rid themselves of the food they have eaten.

Correct answer: B

Rationale: The correct answer is B because individuals with binge-eating disorder do not typically engage in purging behavior, unlike those with bulimia. Choice A is incorrect as individuals with binge-eating disorder do not purge the food they eat, so they do not eat smaller portions before doing so. Choice C is incorrect as they do not purge their food after several binge sessions. Choice D is incorrect as individuals with binge-eating disorder do not resort to anorexic methods to rid themselves of the food they have eaten.

5. Which part of your brain is active when you get cues about being hungry, thirsty, or sleepy?

• A. Hippocampus
• B. Thalamus
• C. Hypothalamus
• D. Amygdala

Correct answer: C

Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.
