English Grammar
1. Which word in the sentence "The quick brown fox jumps over the lazy dog" demonstrates alliteration?
- A. quick
- B. brown
- C. fox
- D. jumps
Correct answer: A
Rationale: Alliteration is the repetition of the first consonant sound of words close together. In this case, "quick" and "brown" both start with the "k" sound.
2. What is the general formula for an alkyl halide?
- A. CnH2n
- B. CnH2n+2
- C. CnH2n-1X
- D. CnH2nO
Correct answer: C
Rationale: The general formula for an alkyl halide is \(C_nH_{2n-1}X\), where X represents a halogen (e.g., F, Cl, Br, I).
3. A car accelerates from rest. What happens to its kinetic energy and work done on it?
- A. Both kinetic energy and work done increase
- B. Kinetic energy increases, but work done remains constant.
- C. Work done increases, but kinetic energy remains constant.
- D. Both kinetic energy and work done remain constant.
Correct answer: A
Rationale: During acceleration, the car's speed increases, leading to rising kinetic energy. Simultaneously, the force applied to accelerate the car does work on it, increasing the work done.
4. What is the function of introns in eukaryotic genes?
- A. They code for protein sequences.
- B. They are involved in gene regulation.
- C. They are removed during mRNA processing.
- D. They are non-functional remnants of ancient DNA.
Correct answer: C
Rationale: Rationale: A) Introns do not code for protein sequences. Exons are the segments of DNA that code for proteins. B) While introns can indirectly influence gene regulation, their primary function is not directly involved in gene regulation. C) Introns are non-coding regions of DNA that are transcribed into pre-mRNA but are removed during mRNA processing through a process called splicing. This allows only the exons to be included in the mature mRNA that will be translated into proteins. D) While introns were once thought to be non-functional remnants of ancient DNA, research has shown that they can have regulatory functions and play a role in gene expression.
5. What is the term for a hydrocarbon chain with no double or triple bonds between carbon atoms?
- A. Saturated
- B. Unsaturated
- C. Aromatic
- D. Alkene
Correct answer: A
Rationale: A saturated hydrocarbon chain has only single bonds between carbon atoms. The other choices are associated with unsaturation or aromaticity.
6. Which term describes the resistance of a substance to flow?
- A. Density
- B. Viscosity
- C. Conductivity
- D. Malleability
Correct answer: b
Rationale: Viscosity refers to the resistance of a substance to flow. Substances with high viscosity flow slowly, while those with low viscosity flow more easily.
