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.

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.

Correct Answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.

Correct Answer: B

Rationale: Permissive parenting is associated with positive developmental outcomes because it involves warmth and a lack of strict control. Authoritarian parenting, as mentioned in choice A, is characterized by strict rules and harsh discipline, which may not lead to the best developmental outcomes. Neglectful parenting, as in choice C, involves a lack of responsiveness and support, which can have detrimental effects on a child's development. Choice D is incorrect because different parenting styles can have varying impacts on child development.

Correct Answer: B

Rationale: Etiology refers to the causal pattern of a disorder, explaining the factors contributing to the development of a specific condition. Choice A is incorrect as it describes a condition that maintains maladaptive behavior, which is not the definition of etiology. Choice C is incorrect as it refers to a predisposition, which is more related to risk factors rather than the cause itself. Choice D is incorrect as it discusses a condition that reduces the negative consequences of stress, which is not directly related to the cause of a disorder.
