Mathematics

1. Scientific notation is a way to represent very large or small numbers in a compact form. If a number is written as 4.82 x 10^3, what is the value of the number in standard form?

Correct answer: C

Rationale: Rationale: When a number is written in scientific notation as \(a \times 10^n\), the value of the number in standard form is obtained by multiplying \(a\) by \(10^n\). In this case, the number is \(4.82 \times 10^3\). To convert this to standard form, we multiply 4.82 by \(10^3\), which means moving the decimal point 3 places to the right. \(4.82 \times 10^3 = 4820\) Therefore, the value of the number in standard form is 4820, which corresponds to option C.

2. What are the differences between RNA and DNA?

Correct answer: B

Rationale: Rationale: A) This statement is incorrect. RNA and DNA have different structures and functions. RNA is involved in protein synthesis and other cellular processes, while DNA stores genetic information. B) This statement is correct. RNA is typically single-stranded, while DNA is double-stranded, forming a double helix structure. C) This statement is correct. RNA contains ribose sugar in its backbone, while DNA contains deoxyribose sugar. D) This statement is incorrect. RNA contains adenine, guanine, cytosine, and uracil, while DNA contains adenine, guanine, cytosine, and thymine.

3. Identify the pronoun in the following sentence: She quickly finished her homework before dinner.

Correct answer: C

Rationale: Pronouns take the place of nouns. "Her" replaces a specific female person's name.

4. What is the process by which damaged muscle tissue repairs and rebuilds itself?

Correct answer: B

Rationale: The correct answer is B: "Regeneration." Regeneration is the process by which damaged muscle tissue repairs and rebuilds itself by replacing the damaged cells with new, healthy cells. Degeneration refers to the deterioration of tissue, not the repair process. Hyperplasia is the increase in cell number, and metaplasia is the transformation of one cell type into another, neither of which directly relate to the repair process of damaged muscle tissue. Therefore, the most appropriate term for the described process is regeneration.

5. A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

Correct answer: A

Rationale: Divide the patient's weight (150 pounds) by the ratio denominator (30 pounds/tablet) to get 5 tablets.

6. Which sentence uses strong verbs to create a more vivid image?

Correct answer: C

Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."
