Explanation:

Question 5

Cellular respiration is a process where cells break down glucose (using oxygen) to produce energy, and carbon dioxide is a waste product. So it consumes oxygen and produces carbon dioxide? Wait, no—wait, the options: Let's recheck. Wait, the options are:

• produces oxygen as waste and consumes carbon dioxide
• consumes oxygen and produces carbon dioxide as waste
• produces both oxygen and carbon dioxide
• consumes both oxygen and carbon dioxide

Wait, no, maybe I mixed up with photosynthesis. Photosynthesis produces oxygen and consumes CO₂. Cellular respiration: cells take in O₂, break down glucose, produce CO₂ as waste. So the correct option should be "consumes oxygen and produces carbon dioxide as waste" (the second option? Wait, the original options in the image: let's parse the text. The first option: "produces oxygen as waste and consumes carbon dioxide" (that's photosynthesis). Second: "consumes oxygen and produces carbon dioxide as waste" (that's cellular respiration). So the correct answer for Question 5 is the option that says "consumes oxygen and produces carbon dioxide as waste" (the second option, but need to check the exact wording. From the image, the options are:

1. produces oxygen as waste and consumes carbon dioxide
2. consumes oxygen and produces carbon dioxide as waste
3. produces both oxygen and carbon dioxide
4. consumes both oxygen and carbon dioxide

So cellular respiration: uses O₂, produces CO₂. So the correct option is the second one: "consumes oxygen and produces carbon dioxide as waste".

In the alveoli of the lungs, gas exchange occurs. Oxygen is in the air (higher concentration in alveolar air than in blood), so oxygen diffuses from air (alveoli) to blood. Carbon dioxide is in blood (higher concentration than in alveolar air), so CO₂ diffuses from blood to air. So the correct option for oxygen diffusion is "Oxygen diffuses from air to blood". The options are:

1. Carbon dioxide diffuses from air to blood
2. Oxygen diffuses from air to blood
3. Carbon dioxide diffuses from blood to air
4. Oxygen diffuses from blood to air

So for oxygen diffusion (the question is about gas exchange in alveoli, specifically oxygen? Wait, the question: "Recall what happens during gas exchange in the alveoli of the lungs." The options: let's check. The correct for oxygen: oxygen moves from alveolar air (high O₂) to blood (low O₂) by diffusion. So the option "Oxygen diffuses from air to blood" (the second option).

Answer:

The option (the second one, e.g., if labeled as B: B. consumes oxygen and produces carbon dioxide as waste)
