Correct Answer: B

Rationale: The term 'selected plants' in this sentence refers to specific or particular plants that have been chosen intentionally for some reason. It implies that not all plants contribute to saturated fat but only specific ones. The term 'particular plants' best captures this meaning in the context provided. Choices A, C, and D are incorrect because 'selected plants' does not necessarily imply they are of top quality, plants that have been restricted, or chosen without reason. The emphasis is on the specificity of the plants chosen, making 'particular plants' the most suitable description.

Correct Answer: D

Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.

Correct Answer: D

Rationale: The outer bone in the lower leg is called the fibula, not fascia, fibrous, or filial. The fibula is a slender bone that runs alongside the larger tibia in the lower leg. While it provides stability and support to leg muscles, its main function is not weight-bearing like the tibia. Therefore, the correct answer is the fibula.

Correct Answer: C

Rationale: In this context, 'projected' is used to indicate an estimation or prediction of the duration of the treatment. Therefore, it aligns closest in meaning to 'estimated.' Choice A, 'Protruded,' means to extend beyond or above a surface, which does not fit the context of the sentence. Choice B, 'Guaranteed,' means to provide assurance, which is not the intended meaning in the sentence. Choice D, 'Alleged,' means to claim without proof, which is not the correct interpretation in this context.

Correct Answer: D

Rationale: The correct answer is D, 'Scar.' A cicatrix is a scar, which is a mark left on the skin or within body tissue after the healing of a wound or injury. Choices A, B, and C ('Beetle,' 'Scalpel,' and 'Antidote') are incorrect as they do not represent synonyms for cicatrix.
