1. The process by which one element changes into another through radioactive decay is known as:

• A. Transmutation
• B. Fission
• C. Fusion
• D. Oxidation

Correct answer: A

Rationale: Transmutation - Radioactive decay alters the atomic structure, changing the element's identity (transmutation).

2. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?

• A. Gravitational force
• B. Tension force
• C. Viscous force
• D. Magnetic force

Correct answer: c

Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.

3. In a neutral atom, the number of electrons:

• A. Must be equal to the number of protons.
• B. Must be less than the number of protons.
• C. Must be greater than the number of neutrons.
• D. Can vary depending on the atom's temperature.

Correct answer: A

Rationale: Must be equal to the number of protons - For electrical neutrality, the positive charge of protons must be balanced by the negative charge of an equal number of electrons.

4. Alexandra is tasked to organize the new wing of the hospital. She was given the authority to

• A. Benevolent –authoritative
• B. Consultative
• C. Exploitive-authoritative
• D. Participative

Correct answer: D

Rationale: The correct answer is D: Participative. In a participative leadership style, Alexandra would involve the team members in decision-making and encourage their input when organizing the new wing of the hospital. This approach fosters collaboration, empowers team members, and can lead to better outcomes as everyone's perspectives are considered. Benevolent-authoritative (A) involves a leader who is kind and caring but makes decisions independently. Consultative (B) involves seeking input from team members but making the final decision independently. Exploitive-authoritative (C) involves a leader who uses their authority in a self-serving or oppressive manner. In this scenario, with the task of organizing a new wing of the hospital, a participative approach would be most effective in engaging the team and utilizing their expertise.

5. The stomach produces a strong acid to help break down food. What is the name of this acid?

• A. Hydrochloric acid
• B. Lactic acid
• C. Bile
• D. Fatty acid

Correct answer: A

Rationale: The correct answer is A: Hydrochloric acid. The stomach produces hydrochloric acid to help break down food by lowering the pH level in the stomach, creating an acidic environment that aids in the digestion of proteins and other nutrients. Lactic acid is produced in muscles during exercise and is not related to stomach digestion. Bile is produced by the liver and helps in the digestion and absorption of fats in the small intestine. Fatty acids are a type of molecule that is a component of fats, not the acid produced by the stomach for digestion.

6. 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.
