Correct Answer: B

Rationale: The correct answer is B: 'Withered.' When a body part atrophies, it shrinks or wastes away. This term is associated with a decrease in muscle mass or tissue due to various reasons like lack of use or injury. Choices A, C, and D are incorrect because atrophy does not refer to enlargement, swelling, or damage, but rather to wasting away or shrinking.

Correct Answer: D

Rationale: The correct answer is D: 'On the side.' Lateral means situated on the side or away from the midline. Choices A, B, and C are incorrect because lateral specifically refers to a position that is situated away from the midline, not near it, at the top of the body, or on the side.

Correct Answer: B

Rationale: The correct answer is B: 'Purified.' Aseptic means free from contamination or sterile. While 'Sterilized' (choice A) is related to the elimination of all microorganisms, aseptic goes beyond sterilization to ensure freedom from contamination in a broader sense. 'Contaminated' (choice C) and 'Polluted' (choice D) are incorrect as they mean the opposite of aseptic, implying the presence of unwanted or harmful substances.

Correct Answer: D

Rationale: The term 'discrete' means individually separate and distinct. Therefore, the most appropriate choice to describe the symptoms that are distinct and separate from each other is 'separate' (option D). Choices A, B, and C are incorrect because they do not convey the specific meaning of the term 'discrete' as separate and distinct.

Correct Answer: B

Rationale: A nutrient is a substance that provides nourishment to the body, such as carbohydrates, proteins, fats, vitamins, and minerals. Choice A has been improved to 'A chemical compound' to be more specific. Choice A is incorrect as it is too general and does not specifically describe the role of a nutrient. Choice C is incorrect as it focuses on minerals without specifying that all minerals are nutrients. Choice D is also incorrect as it solely emphasizes vitamins, which are just one type of nutrient.
