Question

1. some problems with the digestive system make it very difficult for the body to digest enough food. why would it be harder to exercise when you have a digestion problem like this?

you would not be able to sleep, which would make you too tired to exercise.

your cells would have molecules from air, but would not get enough molecules from food

you would need to breathe in a lot more air because your body would have fewer molecules from food.

you would not get any of the molecules your cells need to exercise.

Explanation:

To solve this, we analyze each option:

• Option 1: Digestion problems don't directly relate to sleep affecting exercise ability, so this is incorrect.
• Option 2: Cells get oxygen (molecules from air) for respiration, but food provides nutrients (molecules like glucose) for energy. If digestion is poor, food - derived molecules (nutrients) are insufficient. This matches the scenario.
• Option 3: The relationship between food - derived molecules and increased air intake isn't a direct or correct explanation for exercise difficulty due to digestion problems.
• Option 4: Saying "no molecules" is extreme. Digestion problems reduce, not eliminate, food - derived molecules.

Answer:

B. Your cells would have molecules from air, but would not get enough molecules from food
