1. He asserts the importance of promoting a positive organizational culture in their unit. Which

A. Proactive and caring with one another
B. Competitive and perfectionist
C. Powerful and oppositional
D. Obedient and uncomplaining

Correct answer: A

Rationale: The correct answer is A: 'Proactive and caring with one another.' When promoting a positive organizational culture, it is essential to foster a supportive environment where individuals are proactive in their approach and demonstrate care towards one another. This type of culture encourages collaboration, open communication, and empathy among team members, leading to higher levels of job satisfaction and overall performance. Being competitive and perfectionist (option B) can create a stressful and unhealthy work environment, while being powerful and oppositional (option C) or obedient and uncomplaining (option D) can stifle creativity and innovation. Therefore, the most suitable traits for promoting a positive organizational culture are being proactive and caring with one another.

2. What happens to the work done on an object when the angle between force and displacement is 90 degrees?

A. Maximum work is done
B. No work is done
C. Minimum work is done
D. Work is infinite

Correct answer: b

Rationale: When the angle between force and displacement is 90 degrees, the work done on the object is zero.

3. How does the amplitude of a wave relate to its intensity or loudness?

A. They are inversely proportional.
B. They are directly proportional.
C. They have no relationship.
D. Amplitude affects frequency, not intensity.

Correct answer: B

Rationale: Higher amplitude corresponds to larger displacement from equilibrium and translates to higher intensity or perceived loudness in sound waves.

4. Where does cellular respiration, the process of converting chemical energy into ATP, take place in eukaryotic cells?

A. Nucleus
B. Ribosomes
C. Mitochondria
D. Golgi apparatus

Correct answer: C

Rationale: Rationale: Cellular respiration, the process of converting chemical energy into ATP, takes place in the mitochondria of eukaryotic cells. The mitochondria are known as the powerhouse of the cell because they are responsible for generating most of the cell's ATP through the process of cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the primary energy currency of the cell. The other organelles listed in the options (nucleus, ribosomes, and Golgi apparatus) do not play a direct role in cellular respiration.

5. A decorative globe has a diameter of 25cm. What is its total surface area?

A. 1570 sq cm
B. 1963 sq cm
C. 2513 sq cm
D. 3142 sq cm

Correct answer: B

Rationale: Use the formula for surface area of a sphere: 4 * Ãâ‚¬ * (radius)^2, where radius is half the diameter. Calculate the radius (12.5cm) and substitute: 4 * Ãâ‚¬ * (12.5cm)^2 Ã¢â€°Ë† 1963 sq cm.

6. What is the relationship between genetic drift and the founder effect?

A. Founder effect is a cause of genetic drift within a small population
B. Genetic drift is a cause of the founder effect in new populations
C. They are the same phenomenon with different names
D. They are unrelated concepts.

Correct answer: A

Rationale: Rationale: - The founder effect is a specific type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation. - Genetic drift, on the other hand, is a broader concept that refers to random changes in allele frequencies in a population over time due to chance events. - Therefore, the founder effect is a specific scenario within the broader concept of genetic drift, where the establishment of a new population by a small number of individuals leads to genetic changes in the population.
