Rationale: The biopsychosocial model differs from the biomedical model by considering biological, psychological, and social factors in understanding health and illness. Choice A is incorrect because the biopsychosocial model does not solely focus on biological aspects. Choice C is incorrect as the biopsychosocial model is not outdated but rather offers a more comprehensive approach. Choice D is incorrect as the two models are distinct in their considerations of factors beyond biology.

Correct Answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

Correct Answer: B

Rationale: Protective factors are influences that modify a person's response to environmental stressors, reducing the likelihood of adverse outcomes. An example of a protective factor is having a warm and caring parent, which can foster resilience in individuals. Resilience allows individuals to adapt successfully to stressful situations. Choice A is incorrect as protective factors do not always prevent adverse consequences but reduce their likelihood. Choice C is incorrect as resilience is the outcome of protective factors, not the other way around. Choice D is incorrect as while protective factors can reduce the risk of psychopathology, they do not always prevent its development.

Correct Answer: C

Rationale: The correct answer is C. Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. It helps regulate metabolism, reduce inflammation, and assist in memory formulation. Choice A is incorrect as cortisol is not released by the hypothalamus and does not travel to the pituitary gland. Choice B is incorrect as cortisol is not released by the pituitary gland but acts on it to regulate hormone production. Choice D is incorrect as cortisol does not reduce the reuptake of monoamine neurotransmitters.

Correct Answer: B

Rationale: Freud's major contribution to current perspectives of mental disorders is the concept of the unconscious and its influence on behavior. While the Oedipal complex (Choice A) and Electra complex (Choice C) are important psychoanalytic concepts introduced by Freud, they are more focused on childhood psychosexual development rather than mental disorders. The understanding of the three structures of personality (Choice D) refers to Freud's id, ego, and superego model, which is essential in psychoanalytic theory but not specifically related to mental disorders.
