Where is the site of chemical communication in the brain?
- A. Neuron
- B. Synapse
- C. Axon
- D. Dendrite
Correct Answer: B
Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.

From the cognitive-behavioral perspective, an important limitation with the behavioral perspective is that ________.
- A. Behaviorists went too far in attacking the psychoanalytic perspective.
- B. Behaviorists failed to attend to the importance of mental processes.
- C. Behaviorists were too focused on explaining how abnormal behavior is acquired.
- D. Behaviorists underestimated the role of reinforcement.
Correct Answer: B
Rationale: The correct answer is B because behaviorists, from the cognitive-behavioral perspective, are criticized for not considering the significance of mental processes. This limitation is a key point in the cognitive-behavioral perspective, which emphasizes the interplay between thoughts, feelings, and behaviors. Choices A, C, and D are incorrect because they do not directly address the specific limitation of failing to account for mental processes in the behavioral perspective.
If having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, the gene is a ________.
- A. risk factor
- B. necessary cause
- C. sufficient cause
- D. contributory cause
Correct Answer: B
Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.
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: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.
How can attributional style influence the likelihood of developing depression?
- A. By fostering a positive attributional style, individuals can enhance their resilience against depression.
- B. Attributional style does not significantly influence the development of depression.
- C. By adopting a negative attributional style, individuals increase their vulnerability to depression.
- D. Attributional style influences the likelihood of developing depression by determining how individuals interpret and respond to events.
Correct Answer: D
Rationale: The correct answer is D because attributional style plays a crucial role in influencing the likelihood of developing depression by shaping how individuals interpret and respond to events. A positive attributional style can indeed enhance resilience against depression by promoting adaptive coping mechanisms and positive interpretations of situations, which can buffer against the development of depressive symptoms. Conversely, a negative attributional style, characterized by attributing negative events to internal, stable, and global factors, can increase vulnerability to depression by fostering feelings of helplessness and hopelessness. Choices A and C provide accurate insights into how different attributional styles can impact the development of depression, making them incorrect. Choice B is incorrect as research indicates that attributional style does have a significant influence on the likelihood of developing depression.
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.
