1. What is the process of cells dividing to produce new cells called?

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

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

2. Which of the following functional groups is present in carboxylic acids?

• A. Carbonyl
• B. Hydroxyl
• C. Carboxyl
• D. Aldehyde

Correct answer: C

Rationale: Carboxylic acids contain the carboxyl functional group (-COOH). The other choices are associated with different functional groups.

3. The final sentence suggests that public discourse about AI should focus on

• A. Celebrating the achievements of AI and promoting its widespread adoption in all sectors.
• B. Criticizing the ethical shortcomings of existing AI systems and demanding stricter regulations.
• C. Engaging in open and informed discussions about the potential benefits, risks, and responsible development of AI.
• D. Focusing solely on the technical challenges of AI development and leaving ethical considerations to experts.

Correct answer: C

Rationale: The emphasis on "ongoing public discourse" and "the future of AI in society" suggests a call for open discussions and collective responsibility, aligning with C.

4. What is the molar mass of Ca(NO3)2?

• A. 74.1 g/mol
• B. 132.1 g/mol
• C. 164.1 g/mol
• D. 78.1 g/mol

Correct answer: b

Rationale: Calculate the molar mass: Ca(40.08) + 2N(14.01) + 6O(16.00) = 132.1 g/mol.

5. Which type of mutation involves a change in the number of chromosomes?

• A. Point mutation
• B. Frameshift mutation
• C. Missense mutation
• D. Aneuploidy

Correct answer: D

Rationale: Rationale: A) Point mutation: Involves a change in a single nucleotide base pair within the DNA sequence. B) Frameshift mutation: Involves the insertion or deletion of nucleotides, causing a shift in the reading frame of the genetic code. C) Missense mutation: Involves a single nucleotide change that results in a codon that codes for a different amino acid. D) Aneuploidy: Involves a change in the number of chromosomes, where an individual may have an extra chromosome (trisomy) or a missing chromosome (monosomy). Aneuploidy can lead to genetic disorders such as Down syndrome (trisomy 21) or Turner syndrome (monosomy X).

6. "Ironic" and "serious" are:

• A. synonyms (have the same meaning)
• B. antonyms (have opposite meanings)
• C. homonyms (sound the same but have different meanings)
• D. none of the above

Correct answer: B

Rationale: "Ironic" means the opposite of "serious."
