1. Which property of a wave determines its energy?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Velocity

Correct answer: b

Rationale: Amplitude is directly related to the energy carried by a wave - higher amplitudes correspond to higher energy waves.

2. Choose the most appropriate word to complete the sentence "He was _____ about his upcoming presentation."

• A. apprehensive
• B. bored
• C. excited
• D. relieved

4. How many moles of oxygen are required to completely react with 5 moles of propane (C3H8) in the combustion reaction?

• A. 5 moles
• B. 10 moles
• C. 15 moles
• D. 20 moles

Correct answer: b

Rationale: The balanced equation is C3H8 + 5O2 → 3CO2 + 4H2O, indicating a 5:10 ratio between moles of oxygen and moles of propane.

6. Which test is commonly used to assess kidney function?

• A. Complete blood count (CBC)
• B. Blood sugar test
• C. Urinalysis
• D. Creatinine clearance test

Correct answer: D

Rationale: The correct answer is D: Creatinine clearance test. This test is commonly used to assess kidney function by measuring how well the kidneys are filtering waste products like creatinine from the blood. Creatinine is a waste product produced by muscles and is normally filtered out by the kidneys. A high level of creatinine in the blood can indicate reduced kidney function. Options A, B, and C are not specifically used to assess kidney function. A complete blood count (CBC) measures different components of the blood like red blood cells, white blood cells, and platelets. A blood sugar test is used to measure glucose levels in the blood. Urinalysis is a test that analyzes the urine for various substances like proteins, glucose, and blood cells, but it is not the primary test for assessing kidney function.
