1. Which blood component is responsible for the production of antibodies?

• A. Platelets
• B. Red blood cells
• C. White blood cells
• D. Plasma cells

Correct answer: C

Rationale: White blood cells, specifically B lymphocytes or B cells, are responsible for producing antibodies as part of the immune response. When the body encounters foreign substances (antigens), B cells are activated to differentiate into plasma cells, which then produce antibodies to target and neutralize the antigens. Platelets are involved in blood clotting and not in antibody production. Red blood cells are primarily responsible for carrying oxygen in the blood and do not produce antibodies. Plasma cells are actually differentiated B cells that produce antibodies, but the question asks for the blood component responsible for the production of antibodies, which is the white blood cells.

2. Simplify the following expression: (1/4) × (3/5) ÷ 1 (1/8)

• A. 8/15
• B. 27/160
• C. 2/15
• D. 27/40

Correct answer: C

Rationale: First, convert the mixed number 1 (1/8) into an improper fraction: 1 (1/8) = 9/8. Now, simplify the expression: (1/4) × (3/5) ÷ (9/8). To divide by a fraction, multiply by its reciprocal: (1/4) × (3/5) × (8/9) = 24/180 = 2/15. Thus, the simplified expression is 2/15. Choice A (8/15) is incorrect because the correct answer is 2/15. Choice B (27/160) is incorrect as it is not the result of the given expression. Choice D (27/40) is incorrect as it does not match the simplified expression obtained.

3. Identify the direct object in the following sentence: 'She baked a delicious cake for the party.'

• A. for the party
• B. delicious
• C. cake
• D. baked

Correct answer: C

Rationale: In the sentence 'She baked a delicious cake for the party,' the verb 'baked' is an action performed by the subject 'She.' The direct object is the recipient of the action, which in this case is 'cake.' It answers the question 'What did she bake?' making 'cake' the direct object in the sentence. Choice A 'for the party' is a prepositional phrase indicating the purpose, not the direct object. Choice B 'delicious' describes the cake but is not the direct object. Choice D 'baked' is the verb itself, not the direct object receiving the action.

4. What is the process of converting lactic acid back into pyruvate called?

• A. Glycolysis
• B. Gluconeogenesis
• C. Cori cycle
• D. Oxidative phosphorylation

Correct answer: C

Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. C) The Cori cycle is the process by which lactic acid produced by anaerobic metabolism in muscles is transported to the liver and converted back into glucose or pyruvate. D) Oxidative phosphorylation is the process by which ATP is synthesized using energy derived from the transfer of electrons in the electron transport chain.

5. Which of the following is an example of deliberate plagiarism?

• A. A student copies an informational source intending to paraphrase it.
• B. A writer forgets to include quotation marks around a direct quote.
• C. A student submits a paper they found on the internet.
• D. A writer omits a source citation because they believe the information is common knowledge.

Correct answer: C

Rationale: The correct answer is C. Submitting a paper found on the internet as one's own work is a clear example of deliberate plagiarism. Choice A is not deliberate plagiarism as the student intends to paraphrase the source, although it may still be considered plagiarism if not properly cited. Choice B is a form of plagiarism known as improper citation but does not involve deliberate intent to pass off someone else's work as one's own. Choice D is also a form of plagiarism known as inadequate citation or failure to attribute, but it does not constitute deliberate plagiarism as the writer's intention is not to deceive but rather a failure in acknowledging sources properly.
