1. Which of the following is a characteristic of a solution with a high viscosity?

• A. It flows easily
• B. It has a low resistance to flow
• C. It has a high resistance to flow
• D. It does not mix with other liquids

Correct answer: c

Rationale: Solutions with high viscosity have a high resistance to flow. The other choices do not accurately describe high viscosity.

2. The phrase "green alternative" suggests that bioremediation is...

• A. The most economical option for plastic cleanup.
• B. Faster and more efficient than traditional methods.
• C. Environmentally friendly and less harmful than other solutions.
• D. More aesthetically pleasing than existing approaches.

Correct answer: C

Rationale: The passage contrasts bioremediation with "traditional methods," explicitly linking it to being environmentally friendly.

3. Which element is used in fertilizers due to its role in plant cell division and growth?

• A. Potassium
• B. Phosphorus
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: Phosphorus is crucial for cell division and metabolism, making it essential for plant growth and development.

4. 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.

5. A routine urinalysis is a common diagnostic test. What does a urinalysis typically evaluate?

• A. Blood sugar levels
• B. Presence of white blood cells (indicating possible infection)
• C. Kidney function
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' A routine urinalysis is a comprehensive test that evaluates various aspects of urine to provide insights into overall health. Blood sugar levels can be assessed to screen for diabetes or monitor diabetes management. The presence of white blood cells in the urine can indicate a possible infection in the urinary tract. Additionally, kidney function can be evaluated by examining factors such as protein levels, creatinine, and electrolytes in the urine. Therefore, a urinalysis typically evaluates blood sugar levels, presence of white blood cells (indicating possible infection), and kidney function, making 'All of the above' the correct choice.

6. The formula for body mass index (BMI) is BMI = weight (kg) / height (m)^2. If a patient's BMI is 25 and their height is 1.7m, what is their weight?

• A. 34kg
• B. 45kg
• C. 56kg
• D. 68kg

Correct answer: C

Rationale: 56kg: Rearrange the formula to solve for weight: weight = BMI * height^2.
