3. A medication dosage is listed as 1/2 teaspoon. What is the equivalent dosage in milliliters (1 teaspoon = 5ml)?

Correct answer: B

Rationale: 2.5ml: Divide the teaspoon dosage (1/2) by the conversion factor (2 teaspoons/5ml).

4. What are chromosomes made of?

Correct answer: B

Rationale: Rationale: Chromosomes are structures found in the nucleus of cells that contain genetic material. They are made up of DNA (deoxyribonucleic acid), which carries the genetic information, and proteins that help in the organization and packaging of the DNA. While RNA is involved in various cellular processes, it is not a major component of chromosomes. Carbohydrates are not a significant component of chromosomes. Therefore, the most accurate answer is B) DNA and proteins.

Correct answer: C

Rationale: Multiply the total solution volume (200ml) by the alcohol percentage (60%)

6. Which of the following factors would NOT affect the solubility of a solid solute in a liquid solvent?

Correct answer: b

Rationale: Pressure does not significantly affect the solubility of solid solutes in liquid solvents. The other choices are factors that can influence solubility.
