1. What figure of speech is used in the statement "His words were a dagger to my heart"?

• A. Metonymy
• B. Simile
• C. Metaphor (Correct)
• D. Hyperbole

Correct answer: C

Rationale: The statement compares the pain of his words to a physical object, forming a metaphor.

2. 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.

3. Identify the bone with the greatest length in the human body.

• A. Femur (Thigh bone)
• B. Humerus (Upper arm bone)
• C. Tibia (Shin bone)
• D. Scapula (Shoulder blade)

Correct answer: A

Rationale: The femur, exceeding a meter in length, bears significant weight and enables locomotion.

4. Acknowledge the organ devoted to blood filtration.

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The kidneys are the primary organs responsible for filtering blood and removing waste products, excess fluids, and toxins. They play a crucial role in maintaining the body's internal environment and regulating blood pressure.

5. When making a dilution, you...

• A. Add more solute to a concentrated solution
• B. Change the temperature of the solution
• C. Decrease the concentration of a solution
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: 'Decrease the concentration of a solution.' When making a dilution, you decrease the concentration of a solution by adding more solvent, not solute. Adding more solute to a concentrated solution would increase the concentration, not dilute it. Changing the temperature of the solution does not directly relate to dilution. Therefore, the only correct statement related to the process of making a dilution is that you decrease the concentration of the solution by adding more solvent, making option C the correct answer.

6. What is the scientific unit used to measure the radioactivity of a substance?

• A. Becquerel (Bq)
• B. Joule (J)
• C. Newton (N)
• D. Kelvin (K)

Correct answer: A

Rationale: Becquerel measures the number of nuclear decays per second in a radioactive sample.
