1. Which of the following structures is unique to eukaryotic cells?

• A. Cell walls
• B. Nuclei
• C. Cell membranes
• D. Vacuoles

Correct answer: B

Rationale: Nuclei are structures that are unique to eukaryotic cells. Prokaryotic cells lack a defined nucleus, and their genetic material floats freely in the cytoplasm. Eukaryotic cells have nuclei that house the genetic material in the form of chromosomes, separated from the cytoplasm by a nuclear membrane. This distinct organelle is a key feature that sets eukaryotic cells apart from prokaryotic cells. Cell walls (Choice A) are found in plant cells, fungi, and some prokaryotes but are not unique to eukaryotic cells. Cell membranes (Choice C) are present in both prokaryotic and eukaryotic cells, serving as a barrier that encloses the cell contents. Vacuoles (Choice D) are membrane-bound organelles found in both plant and animal cells, making them not unique to eukaryotic cells.

2. Which of the following choices shows the best chronological order for the sentences within the paragraph?

• A. IV, II, I, III
• B. III, IV, II, I
• C. I, II, III, IV
• D. III, I, IV, II

Correct answer: C

Rationale: The correct chronological order for the sentences within a paragraph should follow the sequence of events logically. In this case, 'I, II, III, IV' is the correct order. Sentence I usually sets the stage or introduces the main idea, followed by sentence II, which provides additional information. Sentence III usually presents the climax or a turning point, leading to sentence IV, which wraps up the paragraph. Choice C, 'I, II, III, IV,' maintains this logical progression, making it the best chronological order. Choices A, B, and D do not follow a coherent chronological sequence and disrupt the flow of events within the paragraph.

3. Based on his work and goals, how should the sentence 'Fred Hampton desired to see lasting social change for African Americans through nonviolent means and community recognition.' be best introduced?

• A. NO CHANGE
• B. Unfortunately,
• C. Finally,
• D. As a result,

Correct answer: D

Rationale: The correct answer is 'D: As a result.' This choice effectively ties Hampton's desire for social change to his ongoing efforts and achievements. 'As a result' indicates a logical connection between Hampton's aspirations and the actions he took to achieve them. Choices B, C, and A are incorrect because they do not provide a suitable transition that connects Hampton's goals with his actions or achievements. 'Unfortunately' (choice B) introduces a negative connotation that is not appropriate in this context. 'Finally' (choice C) suggests a chronological sequence rather than a cause-and-effect relationship. 'NO CHANGE' (choice A) does not establish a clear link between Hampton's desires and his efforts for social change.

4. 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.

5. How many molecules of NADPH and ATP are required to reduce 6 molecules of CO2 to glucose via photosynthesis?

• A. 6 NADPH and 9 ATP
• B. 12 NADPH and 18 ATP
• C. 18 NADPH and 24 ATP
• D. 24 NADPH and 36 ATP

Correct answer: B

Rationale: During photosynthesis, 12 molecules of NADPH and 18 molecules of ATP are required to reduce 6 molecules of CO2 to glucose. NADPH and ATP are essential energy carriers in the process of photosynthesis. Choice A is incorrect because it underestimates the required molecules of both NADPH and ATP. Choices C and D overestimate the number of molecules needed, making them incorrect answers.
