Reading
1. What is the main idea of the passage?
- A. Petra is a modern city built for tourism.
- B. Petra's historical significance lies in its architectural achievements.
- C. Petra's prosperity was linked to its strategic location on trade routes.
- D. Petra's obscurity remains a mystery despite its rediscovery.
Correct answer: C
Rationale: B mentions Petra's architecture, but not its connection to trade. A and D are factually incorrect and not supported by the passage. Choice C accurately identifies Petra's rise and fall as tied to its position on the Silk Road, making it the main idea.
2. Which of these is NOT a function of the large intestine?
- A. Absorbing water and electrolytes
- B. Producing vitamins
- C. Breaking down fiber
- D. Eliminating waste products
Correct answer: B
Rationale: Rationale: A) Absorbing water and electrolytes: The large intestine plays a crucial role in absorbing water and electrolytes from the indigestible food matter that passes through it. This helps in maintaining the body's fluid balance and preventing dehydration. B) Producing vitamins: While the large intestine contains bacteria that can produce some vitamins like vitamin K and certain B vitamins, the primary site for vitamin production is the small intestine and other organs like the liver. C) Breaking down fiber: The large intestine is responsible for breaking down fiber that was not digested in the small intestine. The bacteria in the large intestine ferment fiber, producing short-chain fatty acids that can be used as an energy source by the body. D) Eliminating waste products: One of the main functions of the large intestine is to eliminate waste products, including indigestible food matter, dead cells, and bacteria, from the body in the form of feces.
3. The process by which a single-celled organism divides into two identical daughter cells is called
- A. Conjugation
- B. Binary fission
- C. Endocytosis
- D. Mitosis
Correct answer: B
Rationale: Rationale: A) Conjugation is a process in which genetic material is transferred between two bacterial cells through a conjugation tube. It does not involve the division of a single-celled organism into two identical daughter cells. B) Binary fission is the process by which a single-celled organism, such as a bacterium, divides into two identical daughter cells. This is a common method of reproduction in prokaryotic organisms. C) Endocytosis is a cellular process in which cells engulf external materials by wrapping them in a vesicle. It is not a method of cell division. D) Mitosis is a type of cell division that occurs in eukaryotic cells, leading to the production of two daughter cells with identical genetic material. However, the question specifically refers to a single-celled organism, which typically undergoes binary fission for reproduction.
4. What are the differences between RNA and DNA?
- A. Both have the same structure and function.
- B. RNA is single-stranded, while DNA is double-stranded.
- C. RNA contains ribose sugar, while DNA contains deoxyribose sugar.
- D. RNA has adenine and guanine, while DNA has thymine and cytosine.
Correct answer: B
Rationale: Rationale: A) This statement is incorrect. RNA and DNA have different structures and functions. RNA is involved in protein synthesis and other cellular processes, while DNA stores genetic information. B) This statement is correct. RNA is typically single-stranded, while DNA is double-stranded, forming a double helix structure. C) This statement is correct. RNA contains ribose sugar in its backbone, while DNA contains deoxyribose sugar. D) This statement is incorrect. RNA contains adenine, guanine, cytosine, and uracil, while DNA contains adenine, guanine, cytosine, and thymine.
5. How can you effectively adapt your writing style to different audiences?
- A. Use the same formal tone regardless of the audience.
- B. Consider the audience's age, background, and level of knowledge.
- C. Rely on jargon and technical terms to sound professional.
- D. Focus on your own voice and writing preferences.
Correct answer: B
Rationale: Effective writing adapts to the audience's needs and background by adjusting vocabulary, tone, and level of detail.
6. Which element is used in insulin and promotes glucose uptake into cells for energy production?
- A. Zinc
- B. Chromium
- C. Manganese
- D. Iron
Correct answer: B
Rationale: Chromium aids in insulin's function, enhancing glucose uptake by cells and regulating blood sugar levels.
