English Grammar
1. What does "voice" refer to in writing style?
- A. The font and typeface used in the text.
- B. The author's unique perspective and personality.
- C. The specific grammar and punctuation rules followed.
- D. The intended audience and purpose of the writing.
Correct answer: B
Rationale: Voice encompasses the author's personality, tone, and overall approach to crafting the written message.
2. Identify the conjunction in the following sentence: He went to the store, but they were already closed.
- A. went
- B. to
- C. but
- D. they
Correct answer: C
Rationale: Conjunctions connect words, phrases, or clauses. "But" joins two contrasting ideas in the sentence.
3. What is the function of the cell membrane?
- A. To protect the cell and control what enters and exits
- B. To store energy
- C. To produce proteins
- D. To synthesize lipids
Correct answer: A
Rationale: Rationale: The cell membrane, also known as the plasma membrane, serves as a protective barrier for the cell, separating the internal environment of the cell from the external environment. It is selectively permeable, meaning it controls the passage of substances in and out of the cell. This regulation of what enters and exits the cell is crucial for maintaining the cell's internal environment and ensuring proper functioning. Options B, C, and D are incorrect because storing energy, producing proteins, and synthesizing lipids are functions carried out by other cellular structures such as mitochondria, ribosomes, and endoplasmic reticulum, respectively, not the cell membrane.
4. Which organelle is responsible for breaking down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks?
- A. Golgi apparatus
- B. Mitochondria
- C. Lysosomes
- D. Endoplasmic reticulum
Correct answer: C
Rationale: Rationale: Lysosomes are membrane-bound organelles containing digestive enzymes that break down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks. These enzymes help in the process of intracellular digestion and recycling of cellular components. The Golgi apparatus is involved in processing and packaging proteins for secretion or for use within the cell. Mitochondria are responsible for producing energy in the form of ATP through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism.
5. In a single displacement reaction, one element takes the place of another element in a compound. Which of the following is an example?
- A. 2H2 + O2 -> 2H2O
- B. Zn + 2HCl -> ZnCl2 + H2
- C. CaCO3 -> CaO + CO2
- D. CH4 + 2O2 -> CO2 + 2H2O
Correct answer: B
Rationale: In a single displacement reaction, one element replaces another element in a compound. Option B, 'Zn + 2HCl -> ZnCl2 + H2,' is an example of a single displacement reaction where zinc (Zn) replaces hydrogen (H) in hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2). The other options do not involve one element displacing another in a compound. Option A is a synthesis reaction, option C is a decomposition reaction, and option D is a combustion reaction. Therefore, option B is the correct answer as it demonstrates the concept of single displacement reactions.
6. Which of the following situations represents work being done on an object?
- A. Pushing against a wall without moving it
- B. Carrying a heavy object without lifting it
- C. Lifting a box to place it on a shelf
- D. Holding a book stationary in your hand
Correct answer: c
Rationale: Work is done when a force is applied to move an object over a distance.
