Answer: Its C moving from a high to a low concentratio
Explanation: i just took the test :)
The gas molecules of oxygen and carbon dioxide are moving from an area of high concentration to an area of low concentration.
DIFFUSION:
- Ideally, fluids (gases and liquids) naturally move from a region where they are in abundance to a region where they are low in abundance.
- This process, which is called diffusion, further means that movement of gaseous molecules is from an area of high concentration to an area of low concentration.
- Therefore, gas molecules of oxygen and carbon dioxide are moving from an area of high concentration to an area of low concentration.
