1. What is the process of cells becoming specialized to perform specific functions called?

• A. Cell division
• B. Cell differentiation
• C. Cell growth
• D. Cell regeneration

Correct answer: B

Rationale: Rationale: A) Cell division refers to the process by which a parent cell divides into two or more daughter cells. B) Cell differentiation is the process by which cells become specialized to perform specific functions. During differentiation, cells acquire specific structures and functions that allow them to carry out particular roles in the body. C) Cell growth is the process by which cells increase in size and number. D) Cell regeneration is the process by which new cells are produced to replace damaged or lost cells in an organism. In this context, the process of cells becoming specialized to perform specific functions is best described as cell differentiation.

2. 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.

3. What is the process of copying DNA called?

• A. Transcription
• B. Translation
• C. Replication
• D. Mutation

Correct answer: C

Rationale: Rationale: A) Transcription is the process of creating an RNA copy of a segment of DNA. It involves the synthesis of mRNA from a DNA template. B) Translation is the process of synthesizing a protein from an mRNA template. It involves the conversion of the mRNA sequence into a sequence of amino acids. C) Replication is the process of copying DNA to produce an identical copy. During replication, the DNA double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules. D) Mutation refers to a change in the DNA sequence that can result from errors during replication, exposure to mutagens, or other factors. While mutations can occur during replication, the process of copying DNA itself is called replication.

4. Which of the following is a unit of power?

• A. Newton-meter (N·m)
• B. Joule (J)
• C. Watt (W)
• D. Kilogram (kg)

Correct answer: c

Rationale: Watt is the unit of power, measuring the rate of work done or energy transfer.

5. When writing dialogue, remember to:

• A. Avoid contractions and informal language for realism.
• B. Use formal vocabulary to sound sophisticated.
• C. Create realistic speech patterns reflecting the characters' personalities.
• D. Focus on descriptive narrative over character interactions.

6. Which of the following is an example of a secondary alcohol?

• A. Methanol
• B. Ethanol
• C. Isopropanol
• D. Butanol

Correct answer: C

Rationale: Isopropanol is an example of a secondary alcohol, as the hydroxyl group is attached to a carbon atom that is bonded to two other carbon atoms. The other choices are primary alcohols.
