1. What is the SI unit of measurement for work?

• A. Newton-meter (N·m)
• B. Joule (J)
• C. Watt (W)
• D. Meter per second (m/s)

Correct answer: b

Rationale: Work is measured in Joules (J) in the SI unit system.

2. Which of the following is an example of an aromatic hydrocarbon?

• A. Ethane
• B. Benzene
• C. Propane
• D. Butene

Correct answer: B

Rationale: Benzene is an example of an aromatic hydrocarbon. The other choices are aliphatic hydrocarbons.

3. Which verb tense is most appropriate for this sentence: "By next week, _____ finished the project."

• A. I will be finishing
• B. I will have finished
• C. I am finishing
• D. I would finish

Correct answer: B

Rationale: Option B expresses a future event completed before another future point in time (next week).

4. What is the term for a group of organisms living in the same place and interacting with each other?

• A. Ecosystem
• B. Community
• C. Population
• D. Niche

Correct answer: B

Rationale: Rationale: - A) Ecosystem refers to a biological community of interacting organisms and their physical environment. - B) Community specifically refers to a group of organisms of different species living in the same place and interacting with each other. - C) Population refers to a group of individuals of the same species living in the same area. - D) Niche refers to the role or function of an organism or species within an ecosystem. In this context, the term for a group of organisms living in the same place and interacting with each other is best described as a community because it involves multiple species interacting within a shared habitat.

5. If you compare a 1 M solution of NaCl to a 1 M solution of glucose (C6H12O6) in water, which solution would have the higher boiling point?

• A. The NaCl solution
• B. The glucose solution
• C. They would have the same boiling point
• D. It depends on the temperature

Correct answer: A

Rationale: The correct answer is A. When a solute is added to a solvent, it raises the boiling point of the solution due to the phenomenon of boiling point elevation. In this case, NaCl is an ionic compound that dissociates into Na+ and Cl- ions in water, leading to more particles in solution compared to glucose, which remains as individual molecules. Since NaCl forms more particles, it causes a greater boiling point elevation, resulting in the NaCl solution having the higher boiling point. Glucose, being a non-electrolyte, does not dissociate and therefore does not contribute as many particles to the solution as NaCl does. Therefore, the NaCl solution would have the higher boiling point.

6. Which of the following is NOT a risk factor for developing atherosclerosis?

• A. High blood pressure
• B. High levels of LDL cholesterol
• C. Regular physical activity
• D. Smoking

Correct answer: C

Rationale: Regular physical activity is NOT a risk factor for developing atherosclerosis. In fact, engaging in regular physical activity can help reduce the risk of developing atherosclerosis by improving cardiovascular health, lowering blood pressure, and reducing LDL cholesterol levels. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. High blood pressure can damage blood vessels, making them more susceptible to plaque buildup. High levels of LDL cholesterol can lead to the accumulation of plaque in the arteries, narrowing the passageways and increasing the risk of atherosclerosis. Smoking is harmful to blood vessels, promoting inflammation and the formation of plaque. Therefore, regular physical activity is actually a protective factor against atherosclerosis rather than a risk factor.
