11b. After a while, you notice the bubbles are no longer forming. You ask your teacher how to make the plant start producing bubbles again, and she tells you to blow through the straw into the water. Why did she suggest that? (1 point)
Blowing through the straw into the water can increase the concentration of carbon dioxide (CO2) in the water. This can stimulate the plant to start producing more bubbles again because plants need carbon dioxide for photosynthesis. By blowing air into the water, you are adding more CO2 for the plant to use, which can help to restart the process of bubble formation.
