1. 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.

2. Two cars with different masses collide head-on. Which car experiences a greater change in momentum?

• A. The car with the larger mass
• B. The car with the smaller mass
• C. Both cars experience the same change in momentum
• D. It depends on the initial velocities of the cars

Correct answer: B

Rationale: The car with the smaller mass. Although momentum is conserved in the collision, the change in momentum is inversely proportional to mass. Therefore, the car with the smaller mass will experience a larger relative change.

3. What property of a wave remains unchanged when it passes from one medium to another with the same speed?

• A. Frequency
• B. Wavelength
• C. Amplitude
• D. Speed

Correct answer: d

Rationale: The speed of a wave remains constant when passing from one medium to another with the same speed.

4. What are some potential applications of understanding atomic structure in modern technology?

• A. Designing new materials with tailored properties.
• B. Developing advanced electronics and nanotechnology
• C. Improving nuclear energy production and safety.
• D. All of the above.

Correct answer: D

Rationale: Understanding atomic structure is crucial in various technological advancements. Designing new materials with tailored properties requires knowledge of atomic structure to manipulate their characteristics. Developing advanced electronics and nanotechnology involves working at the atomic level to create smaller, faster, and more efficient devices. Improving nuclear energy production and safety also relies on understanding atomic structure to enhance reactor design and safety measures. Therefore, all of the options provided (A, B, and C) are potential applications of understanding atomic structure in modern technology.

5. Tight junctions are specialized regions between animal cells that perform which function?

• A. Communication between cells
• B. Anchorage between cells
• C. Selective passage of materials
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Tight junctions are specialized structures between animal cells that serve multiple functions. They facilitate communication between cells by allowing signaling molecules to pass through. Additionally, tight junctions provide anchorage between cells, helping to maintain tissue structure and integrity. Moreover, tight junctions regulate the selective passage of materials across cell layers, acting as a barrier to prevent the free diffusion of substances. Therefore, all the functions mentioned in the options are performed by tight junctions, making 'All of the above' the correct choice.

6. Stephanie delegates effectively if she has authority to act, which is BEST defined as:

• A. having responsibility to direct others
• B. being accountable to the organization
• C. having legitimate right to act
• D. telling others what to do

Correct answer: A

Rationale: The correct answer is A: 'having responsibility to direct others.' Effective delegation involves entrusting tasks and responsibilities to others while still maintaining ultimate accountability. Authority to act means having the responsibility to direct others, making decisions, and overseeing the completion of tasks. This definition aligns with the core concept of delegation, where individuals are empowered and authorized to carry out specific duties. Being accountable to the organization (option B) is important but does not fully capture the proactive nature of delegation. Having a legitimate right to act (option C) is essential for effective delegation, but it is more about the formal authorization rather than the active responsibility to direct others. Simply telling others what to do (option D) is a narrow and authoritarian view of delegation that does not encompass the collaborative and empowering nature of effective delegation.
