1. What is the function of ribosomal RNA (rRNA)?
- A. Carries amino acids to the ribosomes
- B. Reads th(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. e genetic code on mRNA
- C. Forms the structural framework of ribosomes
- D. Controls the rate of protein synthesis
Correct answer: C
Rationale: Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes, which are the cellular organelles responsible for protein synthesis. Ribosomes consist of both protein and rRNA components, with rRNA providing the structural support necessary for the ribosome to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during the process of translation, where the genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, the primary function of rRNA is to contribute to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis.
2. Which of the following guidelines should be least considered in formulating objectives for
- A. Written nursing care plan
- B. Holistic approach
- C. Prescribed standards
- D. Staff preferences
Correct answer: D
Rationale: When formulating objectives for a written nursing care plan, staff preferences should be the least considered guideline. Objectives in a care plan should be based on the patient's needs, evidence-based practices, and prescribed standards of care to ensure quality and effective treatment. Staff preferences may introduce biased decisions that do not align with the best interests of the patient. It is crucial to prioritize holistic care, which considers all aspects of the patient's well-being, and adhere to prescribed standards to provide comprehensive and individualized care. By disregarding staff preferences and focusing on what is best for the patient, healthcare professionals can deliver optimal care that promotes patient outcomes and satisfaction.
3. The phrase "robust ethical frameworks" refers to
- A. Complex algorithms and mathematical models used in AI development.
- B. Comprehensive sets of guidelines and regulations governing AI development and deployment.
- C. Advanced hardware and software systems necessary for building powerful AI systems.
- D. Public education campaigns raising awareness about the potential benefits and risks of AI.
Correct answer: B
Rationale: Ethical frameworks are sets of principles and guidelines that ensure responsible AI development and address potential risks, aligning with B.
4. The element with the atomic number 17 is:
- A. Chlorine (Cl)
- B. Nitrogen (N)
- C. Sodium (Na)
- D. Fluorine (F)
Correct answer: A
Rationale: Chlorine (Cl) - Chlorine has 17 protons, corresponding to atomic number 17.
5. The author's attitude towards history seems to be
- A. indifferent and neutral, presenting it as an objective field of study.
- B. critical and dismissive, questioning its practical applicability in the present.
- C. enthusiastic and optimistic, highlighting its potential to guide the future.
- D. pessimistic and cautious, emphasizing the risk of repeating past mistakes.
Correct answer: C
Rationale: The passage's overall tone highlights the value and utility of history, showcasing its potential to inspire and guide us, suggesting an optimistic and encouraging view.
6. Identify the participial phrase in the following sentence: "Running through the park, she spotted a squirrel."
- A. Running
- B. through the park
- C. she spotted
- D. a squirrel
Correct answer: B
Rationale: A participial phrase acts as an adjective but is formed from a verb.
