1. During gas exchange in the alveoli, what happens to oxygen?

Correct answer: B

Rationale: During gas exchange in the alveoli, oxygen is absorbed from the alveoli into the bloodstream. In the alveoli, oxygen diffuses across the thin walls of the alveoli and into the surrounding capillaries where it binds to hemoglobin in red blood cells. This oxygen-rich blood is then transported to the body's tissues for cellular respiration. Therefore, option B is correct as it accurately describes the direction of oxygen movement during the process of gas exchange in the lungs.

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

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.

3. Which element has the same number of protons and neutrons?

Correct answer: D

Rationale: Helium (He) - He-4 has 2 protons and 2 neutrons, while the other options have differing numbers.

4. Which blood type is a universal donor?

Correct answer: D

Rationale: Rationale: Blood type O is considered the universal donor because individuals with type O blood can donate red blood cells to individuals with any ABO blood type (A, B, AB, or O) without causing an adverse reaction. This is because type O blood lacks A or B antigens on the surface of red blood cells, which helps minimize the risk of an immune response when transfused into individuals with different blood types. Therefore, type O blood is in high demand for blood transfusions in emergency situations when the recipient's blood type is unknown or when there is a shortage of specific blood types.

5. What property of a substance remains constant regardless of its location in the universe?

Correct answer: a

Rationale: Mass is an intrinsic property of matter that remains constant regardless of its location in the universe.

6. What describes the change in direction of light when it passes through different mediums, such as air and water?

Correct answer: c

Rationale: Refraction is the bending of light as it passes from one medium to another with different optical densities, causing a change in direction.
