English Grammar
1. The phrase "a bold new world" is an example of
- A. Hyperbole
- B. Oxymoron
- C. Simile
- D. Metaphor
Correct answer: B
Rationale: An oxymoron combines contradictory terms, like "bold new" signifying the unexpected and promising nature of the world.
2. A stop sign has five equal sides, each measuring 25cm. What is its perimeter?
- A. 100cm
- B. 125cm
- C. 150cm
- D. 175cm
Correct answer: B
Rationale: Multiply the side length by the number of sides: perimeter = number of sides * side length = 5 * 25cm = 125cm.
3. Which of the following is NOT a function of the cilia lining the respiratory tract?
- A. Trapping inhaled dust and debris
- B. Moistening inhaled air
- C. Producing mucus
- D. Propelling mucus upwards towards the throat
Correct answer: C
Rationale: The correct answer is C: 'Producing mucus.' Cilia lining the respiratory tract do not produce mucus, but rather move the mucus that is produced by other cells. The cilia work together to propel the mucus upwards towards the throat, where it can be either swallowed or expelled. Trapping inhaled dust and debris, moistening inhaled air, and propelling mucus upwards are all important functions of the cilia in the respiratory tract, helping to protect the lungs and maintain respiratory health.
4. The muscular tube that transports sperm from the testes to the urethra is called the:
- A. Epididymis
- B. Vas deferens
- C. Seminal vesicle
- D. Cowper's gland
Correct answer: B
Rationale: The correct answer is B: Vas deferens. The vas deferens is a muscular tube that carries sperm from the testes to the urethra. It is an essential part of the male reproductive system, allowing for the transport of sperm for ejaculation. The epididymis is a coiled tube where sperm mature and are stored, not where they are transported to the urethra. The seminal vesicle and Cowper's gland are accessory glands that contribute fluids to semen but are not part of the direct pathway for sperm transport.
5. What is the functional group present in esters?
- A. Hydroxyl
- B. Carbonyl
- C. Ester
- D. Amine
Correct answer: C
Rationale: Esters have the functional group -COO-, representing a carbonyl group bonded to an oxygen atom. The other choices are associated with different functional groups.
6. What is the name of the microscopic finger-like projections that increase the surface area for absorption in the small intestine?
- A. Goblet cells
- B. Paneth cells
- C. Villi
- D. Crypts of Lieberkühn
Correct answer: C
Rationale: Rationale: A) Goblet cells: Goblet cells are specialized cells that secrete mucus to protect the lining of the digestive tract. While important for maintaining the health of the intestines, goblet cells do not increase the surface area for absorption in the small intestine. B) Paneth cells: Paneth cells are specialized cells found in the small intestine that secrete antimicrobial peptides. They play a role in protecting the intestinal stem cells and maintaining the gut microbiota balance, but they do not increase the surface area for absorption. C) Villi: Villi are microscopic finger-like projections found in the small intestine that increase the surface area available for absorption of nutrients. Each villus contains blood vessels and lacteals (lymphatic vessels) that help absorb nutrients from digested food. D) Crypts of Lieberkühn: Crypts of Lieberkühn are small pits located between the villi
