1. What is the term for the number of moles of solute per liter of solution?

• A. Molarity
• B. Molality
• C. Normality
• D. Concentration

Correct answer: A

Rationale: Molarity is defined as the number of moles of solute per liter of solution. The other choices are different concentration units.

2. What is the term for the particles moving around within a substance?

• A. Ions
• B. Atoms
• C. Molecules
• D. Kinetic energy

Correct answer: C

Rationale: In most cases, the particles moving within a substance are individual molecules or atoms, depending on the state of matter.

3. Bile, a digestive juice, is produced by which organ?

• A. Stomach
• B. Liver
• C. Pancreas
• D. Small intestine

Correct answer: B

Rationale: The correct answer is B: Liver. Bile is a digestive juice that is produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion and absorption of fats in the small intestine. The stomach primarily produces gastric juices that aid in breaking down food, while the pancreas secretes digestive enzymes and bicarbonate into the small intestine. The small intestine is responsible for the absorption of nutrients. Therefore, the liver is the organ that produces bile, making it the correct answer to this question.

4. What are enzymes?

• A. Building blocks of muscle
• B. Biological catalysts
• C. Energy source
• D. Antibodies

Correct answer: B

Rationale: Enzymes are proteins that speed up chemical reactions in our cells. They act like tiny factories, fitting specific molecules (substrates) into their active site to facilitate reactions.

5. A person pushes a box across a floor with a constant force. The box eventually comes to a stop due to friction. What happens to the work done by the person?

• A. It increases as the box moves further.
• B. It decreases as the box slows down.
• C. It remains constant throughout the motion.
• D. It becomes zero once the box stops.

Correct answer: C

Rationale: Work is defined as force multiplied by distance, and as long as the force remains constant, the work done increases proportionally to the distance moved, even if the box slows down due to friction.

6. The study of fungi is known as:

• A. Virology
• B. Mycology
• C. Bacteriology
• D. Parasitology

Correct answer: B

Rationale: Rationale: A) Virology is the study of viruses, not fungi. B) Mycology is the branch of biology that deals with the study of fungi. Fungi are a separate kingdom of organisms that include yeasts, molds, and mushrooms. C) Bacteriology is the study of bacteria, not fungi. D) Parasitology is the study of parasites, which can include various organisms such as protozoa, helminths, and some fungi, but it is not specifically focused on fungi.
