What is the crystalline compound that is a product of protein metabolism known as?
- A. uracil
- B. urine
- C. ureter
- D. urea
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.

A restricted diet is ___________.
- A. low in fat
- B. vegetarian
- C. banned
- D. limited
Correct Answer: D
Rationale: A restricted diet is limited in some way, such as reducing the intake of certain foods, food groups, or nutrients. It may involve limitations on quantity, frequency, or types of foods consumed. This restriction could be related to health factors, allergies, sensitivities, ethical reasons, or personal preferences. Choice A, 'low in fat,' is too specific and does not encompass the broad concept of restriction in a diet. Choice B, 'vegetarian,' refers to a specific dietary pattern but does not necessarily indicate restriction. Choice C, 'banned,' is incorrect as it implies a complete prohibition rather than limitation, which is characteristic of a restricted diet.
Choose the meaning of the word 'supplement' in the following sentence: 'Calcium pills may be used to supplement your diet.'
- A. Replace
- B. Add to
- C. Reflect
- D. Parallel
Correct Answer: B
Rationale: In the context of the sentence, the word 'supplement' is used to mean adding something extra to enhance or complete the diet. Therefore, the meaning of the word is 'add to.'
Choice A ('Replace') is incorrect because 'supplement' does not mean to substitute or exchange.
Choice C ('Reflect') is incorrect because 'supplement' does not mean to mirror or show.
Choice D ('Parallel') is incorrect because 'supplement' does not mean to correspond or be similar in a particular way.
What is another word for elated?
- A. Edified
- B. Confused
- C. Flabbergasted
- D. Delighted
Correct Answer: D
Rationale: The word 'elated' means to be ecstatically happy or joyful. Similarly, 'delighted' also means to be extremely pleased or filled with joy. Therefore, 'delighted' is another word that could be used to express the same meaning as 'elated.' Choices A, B, and C are incorrect. 'Edified' means to instruct or enlighten, 'confused' means to be unclear or bewildered, and 'flabbergasted' means to be astonished or amazed, which do not convey the same meaning as 'elated.'
