1. Javier is writing a persuasive essay about the role of government in education. He has outlined his paper, written a draft, and revised his draft. Which of the following steps in the writing process has NOT been completed?

• A. Brainstorm topics
• B. Research reliable sources
• C. Write a second draft
• D. Select a topic

Correct answer: A

Rationale: The correct answer is A. Javier has already outlined his paper, written a draft, and revised it. Brainstorming topics typically occurs at the initial stages of the writing process to generate ideas and develop a focus. Since Javier has already completed a draft, the brainstorming step has not been done. Choices B, C, and D are incorrect because Javier has already conducted research, written a draft, and selected a topic for his essay.

2. Which of the following root words means far?

• A. tele
• B. trans
• C. post
• D. ante

Correct answer: A

Rationale: The correct answer is 'tele,' which means far. This root word is commonly found in words like 'telephone' and 'television,' where 'tele' indicates a distance or far-reaching transmission. 'Trans' (choice B) means across or beyond, not specifically far. 'Post' (choice C) means after or later, and 'ante' (choice D) means before or prior, neither of which conveys the meaning of far.

3. What are the two primary functions of the respiratory system?

• A. Delivering nutrients and removing CO2
• B. Delivering O2 and removing CO2, maintaining blood pH
• C. Maintaining blood pH and delivering nutrients
• D. Delivering O2 and nutrients to the cells

Correct answer: B

Rationale: The correct answer is B. The respiratory system's primary functions include delivering oxygen (O2) to the body's cells for cellular respiration and removing carbon dioxide (CO2), thereby aiding in the maintenance of blood pH. These functions are crucial for gas exchange and the overall metabolic processes within the body. Choice A is incorrect as the respiratory system primarily delivers O2, not nutrients, and removes CO2, not delivering it. Choice C is incorrect as while the respiratory system helps maintain blood pH by removing CO2, it does not primarily deliver nutrients. Choice D is incorrect as it combines the functions of delivering O2 and nutrients, which are distinct roles of different systems in the body.

4. What is the Golgi apparatus?

• A. A network of tubules that transport proteins and lipids throughout the cell
• B. A sac-like structure that stores water and nutrients
• C. The site of protein synthesis
• D. The site of protein modification and packaging

Correct answer: D

Rationale: The Golgi apparatus is an organelle in the cell responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It consists of a series of flattened sacs called cisternae and plays a crucial role in processing proteins synthesized in the endoplasmic reticulum. Option A is incorrect because the network of tubules that transport proteins and lipids throughout the cell is typically associated with the endoplasmic reticulum. Option B is incorrect as the structure described is more characteristic of a vacuole, which stores water and nutrients. Option C is incorrect as protein synthesis primarily occurs in the ribosomes, not the Golgi apparatus.

5. What is the process by which RNA molecules are modified after transcription but before translation?

• A. Replication
• B. Splicing
• C. Editing
• D. Packaging

Correct answer: B

Rationale: B) Splicing is the correct answer. Splicing is the process by which non-coding regions (introns) are removed from pre-mRNA, and the remaining coding regions (exons) are joined together to form mature mRNA. This modification occurs after transcription but before translation. A) Replication is incorrect as replication is the process by which DNA is copied to produce a new DNA molecule, not RNA modifications. C) Editing may involve RNA editing, but it is not commonly used to describe the modification of RNA molecules after transcription. D) Packaging is not the correct term as it refers to the condensation and organization of DNA into chromatin in eukaryotic cells, not the modification of RNA molecules.
