<u><em>Growing plants in space is tough -- low gravity means water distribution is difficult to manage, the roots are often starved of oxygen, and stagnant air reduces evaporation and increases the leaf temperature</em></u>
Answer: D
Explanation:
The oven probably isn’t cooking right because the temperature strength is not as strong as the average oven.
The peas haven't start germinating, which means no leaves. They can't undergo photosynthesis to produce oxygen. At this stage they are still undergoing respiration, which produce carbon dioxide.
