Question

1. the space exploration program has hired you for advice on how to keep astronauts healthy in the space shuttle. how can the programs doctors make sure the astronauts bodies work well enough to exercise in space? the doctors could make sure that the astronauts bodies can make enough energy by getting enough sleep. the doctors could make sure the astronauts stomachs are getting the molecules they need from food and air. the doctors could make sure the astronauts cells are getting the molecules they need from food and air the doctors could make sure the astronauts cells are getting different types of molecules from food.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Sleep is important for health, but it doesn't directly relate to cells getting molecules for energy production needed for exercise.
• Option 2: Stomachs digest food, but the key is cells receiving necessary molecules (from food and air, as air provides oxygen for cellular respiration), not just the stomach's role.
• Option 3: Cells need molecules from food (like glucose) and air (oxygen) to perform cellular respiration and produce energy. This is essential for the body to function well enough to exercise.
• Option 4: Cells need molecules from both food and air (oxygen), not just different types from food. So this is incomplete.

Answer:

C. The doctors could make sure the astronauts’ cells are getting the molecules they need from food and air
