1. Which macromolecule serves as the repository of genetic information in all living organisms?

• A. Ribonucleic acid (RNA)
• B. Deoxyribonucleic acid (DNA)
• C. Protein
• D. Carbohydrate

Correct answer: B

Rationale: - DNA is the macromolecule that serves as the repository of genetic information in all living organisms. It carries the genetic instructions necessary for the growth, development, functioning, and reproduction of organisms. - RNA (option A) is involved in various cellular processes, including protein synthesis, but DNA is the primary molecule responsible for storing genetic information. - Proteins (option C) are essential for various cellular functions but do not serve as the primary repository of genetic information. - Carbohydrates (option D) are important for energy storage and structural support but do not store genetic information.

2. What is the primary function of the large intestine?

• A. To digest food
• B. To absorb water and form feces
• C. To absorb proteins
• D. To regulate blood pressure

Correct answer: B

Rationale: The correct answer is B. The primary function of the large intestine is to absorb water from digested food and form feces for elimination. It does not primarily digest food, absorb proteins, or regulate blood pressure. Choice A is incorrect because the large intestine does not digest food but rather absorbs nutrients and water. Choice C is incorrect as the absorption of proteins primarily occurs in the small intestine. Choice D is incorrect as the regulation of blood pressure is not a primary function of the large intestine.

3. Which of the following most accurately describes how the argument proceeds?

• A. The argument proceeds by stating a conclusion, then providing supporting evidence.
• B. The argument proceeds by stating several facts and drawing a conclusion.
• C. The argument proceeds by offering a premise, then refuting it.
• D. The argument proceeds by making a comparison between two subjects.

Correct answer: A

Rationale: The correct answer is A. The argument in the text proceeds by stating a conclusion ('Dwight is the best employee') and then providing supporting evidence ('The top salesman is always the best employee'). This aligns with choice A, where the argument is structured by stating a conclusion first and then offering supporting evidence. Choices B, C, and D are incorrect because the argument in the text does not simply present facts and draw a conclusion, offer a premise and then refute it, or make a comparison between two subjects.

4. Which of the following is the plural of the word chief?

• A. Chiefs
• B. Chieves
• C. Chievs
• D. Chiefes

Correct answer: A

Rationale: The correct answer is 'Chiefs.' When making the word 'chief' plural, the correct form is 'Chiefs.' Choices B, C, and D are incorrect as they do not follow the standard rules for forming plurals in English. 'Chieves,' 'Chievs,' and 'Chiefes' are not valid plural forms of 'chief.' It's important to understand the basic rules of pluralization in English to form correct plural nouns.

5. What is the primary function of the kidneys?

• A. To digest food
• B. To filter blood and produce urine
• C. To absorb nutrients
• D. To transport oxygen

Correct answer: B

Rationale: The primary function of the kidneys is to filter blood and remove waste products from the body, producing urine in the process. This function helps in maintaining the body's internal environment stable, a process known as homeostasis. Option A, 'To digest food,' is incorrect as digestion primarily occurs in the gastrointestinal system, not in the kidneys. Option C, 'To absorb nutrients,' is also incorrect because nutrient absorption mainly takes place in the intestines. Option D, 'To transport oxygen,' is incorrect as the lungs and circulatory system are responsible for oxygen transport, not the kidneys.
