Correct Answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.

Correct Answer: B

Rationale: The correct answer is B: 'Snub.' To ostracize someone means to intentionally exclude or ignore them. Choices A, C, and D are incorrect because ostracize has a negative connotation, opposite of 'Praise,' 'Accept,' and 'Include.' Ostracize involves rejecting or isolating someone, which contrasts with the positive actions associated with the other choices.

Correct Answer: B

Rationale: When patients are being counseled, they are being advised or guided. Counseling involves providing support, guidance, and advice to help patients cope with their challenges.

Choice D is incorrect because while comfort may be a part of counseling, the primary focus is on providing guidance and advice to address issues, not just comfort.

Correct Answer: A

Rationale: The correct answer is A: 'Thick and sticky.' Viscous describes a substance that is thick and sticky, resisting flow easily. Choices B, C, and D are incorrect.

Correct Answer: A

Rationale: Refrain is another word for abstain, as both words mean to resist or hold oneself back from doing something.

Adhere (choice C) means to stick to or follow closely, while eliminate (choice D) means to completely remove or get rid of something. Therefore, the correct answer is A, 'Refrain,' which is a synonym for 'abstain.'
