1. What is the difference between emphysema and chronic bronchitis, both chronic obstructive pulmonary diseases (COPD)?
- A. Emphysema damages alveoli, while chronic bronchitis inflames airways.
- B. Emphysema causes coughing, while chronic bronchitis leads to shortness of breath.
- C. Emphysema is more reversible than chronic bronchitis.
- D. Emphysema affects only smokers, while chronic bronchitis can occur in non-smokers.
Correct answer: A
Rationale: The correct answer is A. Emphysema and chronic bronchitis are both types of COPD, but they have distinct characteristics. Emphysema is characterized by the destruction of the alveoli in the lungs, which impairs the exchange of oxygen and carbon dioxide. This damage to the alveoli leads to difficulty breathing and decreased lung function. On the other hand, chronic bronchitis involves inflammation and narrowing of the airways, leading to excessive mucus production and a persistent cough. While both conditions are chronic and progressive, emphysema primarily affects the alveoli, while chronic bronchitis primarily affects the airways. Understanding these differences is crucial for appropriate diagnosis and management of COPD.
2. A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Divide the patient's weight (150 pounds) by the ratio denominator (30 pounds/tablet) to get 5 tablets.
3. Which sentence uses the comparative degree of an adjective correctly?
- A. This movie is good, but the other one is better.
- B. She is the tallest player on the team.
- C. He worked hardest than everyone else.
- D. My coffee is hotter than yours.
Correct answer: A
Rationale: Option A uses "better" to compare the quality of two movies.
4. How is work defined in terms of force and displacement?
- A. Work is the product of force and displacement in any direction
- B. Work is done only when the displacement is vertical
- C. Work is done only when the force and displacement are perpendicular
- D. Work is the product of force and displacement in the direction of the force
Correct answer: d
Rationale: Work is calculated as the force applied to an object multiplied by the displacement of the object in the direction of the force.
5. Which sentence uses the colon correctly?
- A. I brought snacks: chips, salsa, and guacamole.
- B. The winner is: Sarah!
- C. He loves all things chocolate: cake, ice cream, and candy bars.
- D. Please bring the following items: pen, paper, and stapler.

6. What is the basic unit of heredity?
- A. Chromosome
- B. Cell
- C. Gene
- D. Organ
Correct answer: C
Rationale: Rationale: A gene is the basic unit of heredity that carries the instructions for making proteins, which determine an organism's traits. Genes are segments of DNA located on chromosomes within the cell. While chromosomes contain many genes, a gene itself is the fundamental unit of heredity responsible for passing on genetic information from one generation to the next. Cells are the basic structural and functional units of living organisms, but genes specifically carry genetic information. Organs are composed of tissues and serve specific functions within an organism, but they are not the basic unit of heredity.
