1. How does an increase in mass affect the force required to produce the same acceleration on an object?

• A. Increases force required
• B. Decreases force required
• C. Has no effect on force required
• D. Causes unpredictable changes in force required

Correct answer: a

Rationale: With an increase in mass, more force is needed to produce the same acceleration due to inertia.

2. On the other hand, Ms. Castro notices that the Chief Nurse Executive has charismatic

• A. Possesses inspirational quality that makes followers gets attracted of him and regards
• B. Acts as he does because he expects that his behavior will yield positive results
• C. Uses visioning as the core of his leadership
• D. Matches his leadership style to the situation at hand.

Correct answer: D

Rationale: The correct answer is D because matching leadership style to the situation at hand is a key aspect of effective leadership. Being able to adapt and adjust leadership approaches based on the specific circumstances and needs of a situation can lead to better outcomes and success. In this scenario, the Chief Nurse Executive's ability to tailor his leadership style to different situations is likely to contribute to his effectiveness in managing various challenges and leading the team effectively.

3. The gradual change in a species over time in response to environmental pressures is best described by:

• A. Punctuated equilibrium (rapid bursts of evolution)
• B. Gradualism (slow and continuous change)
• C. Founder effect (genetic drift in a small population)
• D. Adaptive radiation (rapid diversification of a species)

Correct answer: B

Rationale: Rationale: A) Punctuated equilibrium refers to rapid bursts of evolution followed by long periods of stability, rather than gradual change over time in response to environmental pressures. B) Gradualism is the process by which species evolve through slow and continuous changes over time in response to environmental pressures. This gradual change can lead to the development of new traits and adaptations. C) Founder effect is a type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not specifically describe the gradual change in a species over time. D) Adaptive radiation is the rapid diversification of a species into a variety of forms to exploit different ecological niches, but it does not specifically refer to the gradual change in response to environmental pressures. Therefore, the best description of the gradual change in a species over time in response to e

4. Define the term "momentum" in physics.

• A. Force exerted on an object
• B. Speed of an object in motion
• C. Mass in motion
• D. Distance traveled per unit time

Correct answer: c

Rationale: Momentum is the product of an object's mass and velocity, describing its motion and resistance to changes in motion.

5. During which phase of the cell cycle does cytokinesis typically occur?

• A. Interphase
• B. Mitosis
• C. Meiosis
• D. G2 phase

Correct answer: B

Rationale: Rationale: Cytokinesis is the process of dividing the cytoplasm of a cell into two daughter cells after the nucleus has divided during mitosis. In the cell cycle, cytokinesis typically occurs at the end of the mitotic phase, following the separation of the duplicated chromosomes into two identical sets in the daughter nuclei. Interphase (option A) is the phase where the cell grows, carries out its normal functions, and prepares for cell division. Meiosis (option C) is a specialized type of cell division that occurs in sexually reproducing organisms to produce gametes. G2 phase (option D) is the phase of the cell cycle following DNA replication in S phase and preceding mitosis, where the cell prepares for cell division.

6. Which molecule is responsible for storing and providing a quick source of energy during short bursts of intense physical activity, such as weightlifting or sprinting?

• A. ATP (Adenosine Triphosphate)
• B. Glucose
• C. Myoglobin
• D. Lactic Acid

Correct answer: a

Rationale: The correct answer is A: ATP (Adenosine Triphosphate). ATP is known as the energy currency of the cell and is responsible for storing and providing quick energy during short bursts of intense physical activity. When muscles require immediate energy for activities like weightlifting or sprinting, ATP is broken down to release energy rapidly. Glucose is a source of energy but needs to be converted into ATP before it can be used by the muscles. Myoglobin is a protein that stores oxygen in muscle cells, not energy. Lactic Acid is produced during intense exercise but is not a direct source of quick energy like ATP.
