1. A bottle of hand sanitizer contains 70% alcohol. If 5ml of sanitizer are used, how much pure alcohol is present?

• A. 1.4ml
• B. 2.1ml
• C. 2.8ml
• D. 3.5ml

Correct answer: D

Rationale: Multiply the total sanitizer volume (5ml) by the alcohol percentage (70%) to get 3.5ml of pure alcohol.

2. Which of the following is the positively charged subatomic particle found in the nucleus of an atom?

• A. Electron
• B. Proton
• C. Neutron
• D. Quark

Correct answer: B

Rationale: Protons are positively charged subatomic particles found in the nucleus of an atom. They have a mass of approximately 1 atomic mass unit (amu) and a charge of +1. The number of protons in an atom's nucleus determines the atomic number of the element, which is a unique identifier for each element.

3. Which term describes the resistance of a substance to flow?

• A. Density
• B. Viscosity
• C. Conductivity
• D. Malleability

Correct answer: b

Rationale: Viscosity refers to the resistance of a substance to flow. Substances with high viscosity flow slowly, while those with low viscosity flow more easily.

4. Which of these organisms belongs to the kingdom Protista?

• A. Coral
• B. Yeast
• C. Euglena
• D. Mushroom

Correct answer: C

Rationale: Rationale: A) Coral belongs to the kingdom Animalia, specifically in the phylum Cnidaria. B) Yeast belongs to the kingdom Fungi. C) Euglena is a unicellular organism that belongs to the kingdom Protista. It is a type of protist that has characteristics of both plants and animals. D) Mushroom belongs to the kingdom Fungi. Therefore, among the options provided, only Euglena belongs to the kingdom Protista.

5. What is the significance of the nuclear envelope breaking down during mitosis?

• A. It allows the chromosomes to condense and become visible.
• B. It allows the spindle apparatus to form and attach to the chromosomes.
• C. It allows the sister chromatids to separate.
• D. It allows the nuclear material to be evenly distributed to the daughter cells.

Correct answer: B

Rationale: Rationale: A) The breakdown of the nuclear envelope does not directly cause the chromosomes to condense and become visible. Chromosome condensation is a separate process that occurs before mitosis begins. B) The breakdown of the nuclear envelope is crucial for the formation of the spindle apparatus, a structure made of microtubules that helps separate the chromosomes during cell division. The spindle apparatus attaches to the chromosomes and helps move them to opposite poles of the cell. C) The separation of sister chromatids occurs during anaphase, which is facilitated by the spindle apparatus. The breakdown of the nuclear envelope is not directly involved in this process. D) The even distribution of nuclear material to daughter cells is achieved through the movement of chromosomes by the spindle apparatus, which is made possible by the breakdown of the nuclear envelope.

6. 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.
