1. A researcher wants to conduct qualitative research. Which method should they use?

• A. Collecting patient narratives
• B. Tracking the dosage of a drug and its blood levels in the patient
• C. Observing a patient's physical changes
• D. Writing journal notes about the research experience

Correct answer: A

Rationale: Qualitative research focuses on gathering non-numerical, descriptive data to explore experiences, behaviors, or perspectives. Collecting patient narratives aligns with qualitative research as it involves capturing detailed accounts of individuals' experiences or viewpoints. Choices B, C, and D involve more quantitative approaches by focusing on measurable quantities, observations, or structured note-taking, which are not characteristic of qualitative research methods.

2. Which structure do cells rely on for movement?

• A. Flagellum
• B. Microtubule
• C. Pili
• D. Vesicle

Correct answer: A

Rationale: The correct answer is A: Flagellum. Cells rely on flagella for movement, which are whip-like structures that propel the cell forward through their whipping motion. Flagella provide motility to single-celled organisms and certain cells in multicellular organisms. Microtubules, on the other hand, provide structural support to the cell and play a role in intracellular transport. Pili are short, hair-like structures used for attachment to surfaces or other cells, not for movement. Vesicles are membrane-bound sacs involved in intracellular transport, aiding in the movement of substances within the cell, but not in the movement of the cell itself.

3. Identify the interjection in the following sentence: Ouch! I stubbed my toe on the table leg.

• A. table
• B. leg
• C. ouch
• D. stubbed

Correct answer: C

Rationale: The correct answer is C, 'ouch'. Interjections are words or phrases used to express strong emotions or sudden feelings. In this sentence, 'ouch' expresses pain, making it an interjection in the given context. Choices A, B, and D are incorrect as they do not represent interjections. 'Table' and 'leg' are nouns, while 'stubbed' is a past tense verb, none of which serve as interjections in this sentence.

4. What is the role of RNA in the regulation of gene expression?

• A. Provides energy for the process
• B. Controls the timing and location of protein synthesis
• C. Translates the genetic code into amino acids
• D. Stores genetic information

Correct answer: B

Rationale: A) RNA does not provide energy for the process of gene expression. Energy is typically provided by molecules like ATP. B) RNA plays a crucial role in controlling the timing and location of protein synthesis through processes like transcriptional regulation, RNA splicing, and post-transcriptional modifications. It helps determine when and where specific proteins are produced in the cell. C) While mRNA translates the genetic code into amino acids during the process of translation, this is not the primary role of RNA in the regulation of gene expression. D) RNA does not store genetic information in the same way that DNA does. DNA is the molecule responsible for storing genetic information in the form of genes. Therefore, option B is the most appropriate choice as it accurately describes the role of RNA in regulating gene expression.

5. Brady had never been skiing before. She took to the slopes like a natural.

• A. Unless
• B. But
• C. Therefore
• D. Before

Correct answer: B

Rationale: The correct answer is 'But.' In this context, 'But' is a conjunction that correctly connects the two independent clauses, indicating a contrast. The first sentence states that Brady had never skied before, while the second sentence reveals that she performed well on the slopes, showing a surprising contrast to her lack of experience. 'Unless' implies a condition that needs to be met for a particular situation, which is not relevant here. 'Therefore' indicates a conclusion or result, which does not fit the context of the contrasting statements. 'Before' is a preposition that doesn't serve the purpose of connecting the two ideas presented in the sentences.
