1. There are times when Katherine evaluates her staff as she makes her daily rounds. Which of

• A. The staff member is observed in natural setting.
• B. Incidental confrontation and collaboration is allowed.
• C. The evaluation is focused on objective data systematically.
• D. The evaluation may provide valid information for compilation of a formal report.

Correct answer: A

Rationale: The correct answer is A: 'The staff member is observed in a natural setting.' This option is the most appropriate because it aligns with the concept of naturalistic observation, where behavior is observed in its natural environment without interference or manipulation. In this scenario, Katherine is observing her staff during her daily rounds without any alterations to their behavior or environment. This allows for a more authentic and unbiased assessment of their performance. Options B, C, and D are not as relevant to the concept of naturalistic observation and do not accurately describe the situation presented in the question.

2. The control center of the cell, containing genetic information (DNA), is the:

• A. Golgi apparatus
• B. Ribosome
• C. Nucleus
• D. Endoplasmic reticulum

Correct answer: C

Rationale: The correct answer is C: Nucleus. The nucleus is the control center of the cell as it contains the cell's genetic material, DNA. It acts as the brain of the cell, regulating gene expression and controlling cell activities. The Golgi apparatus is responsible for packaging and processing proteins, the ribosomes are involved in protein synthesis, and the endoplasmic reticulum is essential for protein and lipid synthesis. However, none of these organelles house the genetic information of the cell, making the nucleus the correct answer in this case.

3. Cherenkov radiation is a characteristic phenomenon associated with:

• A. Alpha particle emission
• B. Beta particle emission
• C. Gamma ray emission
• D. Charged particles exceeding the speed of light in a medium

Correct answer: C

Rationale: Cherenkov radiation is a phenomenon associated with charged particles exceeding the speed of light in a medium. When a charged particle travels faster than the speed of light in that medium, it emits a characteristic blue glow known as Cherenkov radiation. This occurs due to the disruption of the electromagnetic field in the medium by the high-speed particle. Options A, B, and C are not correct as they do not directly relate to the specific condition required for Cherenkov radiation to be produced. Therefore, option D, 'Charged particles exceeding the speed of light in a medium,' is the correct answer.

4. Which of the following factors would NOT affect the solubility of a solid solute in a liquid solvent?

• A. Temperature
• B. Pressure
• C. Particle size
• D. Nature of the solute and solvent

Correct answer: b

Rationale: Pressure does not significantly affect the solubility of solid solutes in liquid solvents. The other choices are factors that can influence solubility.

5. He wants to influence the customary way of thinking and behaving that is shared by the

• A. Organizational chart
• B. Cultural network
• C. Organizational structure
• D. Organizational culture

Correct answer: A

Rationale: The correct answer is A: "Organizational chart." In the context of the question, the individual is aiming to impact the established patterns of thinking and behavior within a group or organization. An organizational chart typically depicts the formal structure of an organization, including roles, relationships, and reporting lines. By influencing the organizational chart, the individual can potentially shape the hierarchical structure and decision-making processes, thereby impacting the customary way of thinking and behaving within the organization. Options B, C, and D do not directly refer to the visual representation of roles and relationships within an organization, making them incorrect choices for this question.

6. The diaphragm is a dome-shaped muscle that plays a crucial role in breathing. When it contracts, what happens?

• A. Air is expelled from the lungs.
• B. The lungs expand to allow air intake.
• C. The vocal cords vibrate to produce sound.
• D. The trachea narrows to control airflow.

Correct answer: B

Rationale: The diaphragm is a dome-shaped muscle located beneath the lungs. When it contracts, it moves downward, creating more space in the chest cavity. This downward movement of the diaphragm allows the lungs to expand, which lowers the air pressure inside the lungs. As a result, air from the outside rushes in to equalize the pressure, leading to inhalation. Therefore, when the diaphragm contracts, it facilitates the intake of air into the lungs, making option B, 'The lungs expand to allow air intake,' the correct answer.
