1. What is the name of the strong acid produced by the stomach to help break down food?

• A. Hydrochloric acid
• B. Lactic acid
• C. Bile
• D. Fatty acid

Correct answer: A

Rationale: The correct answer is A, hydrochloric acid. The stomach produces hydrochloric acid to aid in the digestion process by breaking down food, particularly proteins. This acid is crucial for the proper absorption of nutrients in the stomach. Lactic acid is produced in muscles during intense exercise, not in the stomach. Bile is produced by the liver to assist in digestion, primarily in the small intestine, not in the stomach. Fatty acids are molecules found in fats with different functions in the body, but they are not the primary acid produced by the stomach for digestion.

2. Which of the following phases of mitosis is characterized by the separation of sister chromatids and their movement to opposite poles?

• A. Metaphase
• B. Anaphase
• C. Telophase
• D. Cytokinesis

Correct answer: B

Rationale: During anaphase of mitosis, the sister chromatids, which are duplicated copies of a chromosome, separate and move towards opposite poles of the cell. This movement is facilitated by the shortening of microtubules attached to the chromatids. As a result, each pole of the cell receives a complete set of chromosomes, ensuring that the daughter cells produced after cell division will have the correct number of chromosomes. Metaphase is characterized by the alignment of chromosomes at the cell's equator, not their separation. Telophase is the phase following anaphase, where the separated chromatids reach the opposite poles and nuclear envelopes start to form around them. Cytokinesis is the final stage of cell division, where the cytoplasm is divided to form two separate daughter cells.

3. Identify the type of clause in the sentence 'When the clock struck midnight, the magic began.'

• A. Main clause
• B. Subordinate clause
• C. Appositive clause
• D. Noun clause

Correct answer: B

Rationale: The clause 'When the clock struck midnight' is a subordinate clause because it does not express a complete thought on its own and depends on the main clause 'the magic began' to form a complete sentence. Subordinate clauses typically begin with subordinating conjunctions like 'when,' 'if,' 'because,' etc., and serve to provide additional information or context to the main clause. Choice A, 'Main clause,' is incorrect because the highlighted clause is not the primary clause that provides the main idea. Choice C, 'Appositive clause,' is incorrect as an appositive clause renames or explains a noun in the sentence, which is not the case here. Choice D, 'Noun clause,' is incorrect as a noun clause functions as a noun within a sentence, and the highlighted clause does not act as a noun but rather as a dependent clause providing contextual information.

4. Which of the following sentences contains an incorrect use of capitalization?

• A. For Christmas, we are driving to the South to visit my grandmother in Mississippi.
• B. Last year, we went to East Texas to go camping in Piney Woods.
• C. Next month, we will visit my Aunt Darla, who lives just east of us.
• D. When my sister-in-law Susan has her baby, I will take the train north to see her.

Correct answer: C

Rationale: The correct answer is C. In this sentence, 'East' should not be capitalized because it is not part of a proper noun. Choices A, B, and D use capitalization correctly. In option A, 'South' and 'Mississippi' are capitalized as they are referring to specific regions. In option B, 'East Texas' and 'Piney Woods' are proper nouns and correctly capitalized. In option D, 'Susan' is a proper noun and capitalized appropriately.

5. What is 0.5 L converted to mL?

• A. 500 mL
• B. 50 mL
• C. 5 mL
• D. 0.5 mL

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters multiplied by 1000 equals 500 milliliters. Choice A, 500 mL, is the correct answer. Choice B, 50 mL, is incorrect as it represents converting 0.05 liters to milliliters. Choice C, 5 mL, is incorrect as it represents converting 0.005 liters to milliliters. Choice D, 0.5 mL, is incorrect as it represents the original amount in milliliters, not the conversion of liters to milliliters.
