1. What is the primary function of DNA polymerase?

• A. Packaging DNA
• B. Replicating DNA
• C. Transcribing DNA
• D. Translating mRNA

Correct answer: B

Rationale: The correct answer is B: Replicating DNA. DNA polymerase is an enzyme responsible for synthesizing new DNA strands during DNA replication. It adds nucleotides to the growing DNA strand based on the template provided by the existing DNA strand. This process ensures that genetic information is accurately copied and passed on to daughter cells during cell division. Option A, Packaging DNA, refers to the coiling and organization of DNA into chromatin, a process involving histones and other proteins. Option C, Transcribing DNA, involves the synthesis of RNA from a DNA template, a process carried out by RNA polymerase. Option D, Translating mRNA, refers to the process of protein synthesis where the information encoded in mRNA is used to assemble amino acids into a polypeptide chain.

2. According to the affixes, which of the following words refers to the love of books?

• A. Logophile
• B. Bibliophile
• C. Discophile
• D. Audiophile

Correct answer: B

Rationale: The correct answer is 'Bibliophile.' The term 'biblio-' is an affix that refers to books, and '-phile' denotes love or attraction. Therefore, 'bibliophile' specifically means a person who loves or collects books. Choice A, 'Logophile,' while containing the '-phile' suffix denoting love, relates to words instead of books. Choices C and D, 'Discophile' and 'Audiophile,' are incorrect as they respectively pertain to music records and sound systems, not books.

3. Which of the following is NOT a prewriting strategy?

• A. Brainstorming
• B. Visual mapping of ideas
• C. Asking questions
• D. Organizing writing into paragraphs

Correct answer: D

Rationale: The correct answer is D. Organizing writing into paragraphs is a component of drafting, which occurs after prewriting. Prewriting involves generating ideas, organizing thoughts, and outlining content before beginning the actual writing process. Choices A, B, and C are all prewriting strategies. Brainstorming helps in generating ideas, visual mapping assists in organizing thoughts spatially, and asking questions helps in exploring different angles of the topic before structuring the content. Therefore, organizing writing into paragraphs is the only option that does not directly relate to prewriting.

4. What is the length of the unknown leg of a right triangle that has one leg measuring 9 feet and a hypotenuse of 19 feet? (Round to the nearest tenth.)

• A. 16.7 feet
• B. 16.0 feet
• C. 17.4 feet
• D. 8.4 feet

Correct answer: A

Rationale: To find the length of the unknown leg (a) of a right triangle, use the Pythagorean theorem: a² + 9² = 19². Substitute the known values, solve for a: a² + 81 = 361. Subtract 81 from both sides to get a² = 280. Taking the square root of 280 gives a ≈ 16.7 feet. Therefore, the correct answer is 16.7 feet. Choice B (16.0 feet) is incorrect as it does not accurately round to the nearest tenth. Choice C (17.4 feet) and choice D (8.4 feet) are incorrect as they do not match the calculated value using the Pythagorean theorem.

5. Using anatomical terms, what is the relationship of the sternum to the deltoid?

• A. Medial
• B. Lateral
• C. Superficial
• D. Posterior

Correct answer: A

Rationale: The sternum is located at the midline of the body, closer to the center, making it medial to the deltoid. The deltoid muscle is positioned on the lateral side of the upper arm, away from the midline. Therefore, the correct relationship of the sternum to the deltoid is medial. 'Lateral' is incorrect as it refers to a position farther away from the midline, 'Superficial' is incorrect as it relates to a structure being closer to the surface, and 'Posterior' is incorrect as it indicates a position behind or toward the back.
