Question

use the information below to answer the question. sue conducts an experiment using elodea, a freshwater plant. she submerges elodea in a test tube containing water and sodium bicarbonate (a source of carbon dioxide) and moves the test tube various distances away from a light source. then she counts the number of bubbles produced in one minute by the cut end of the elodea. use the knowledge of photosynthesis to select the correct option to complete the observations sue made. if the number of elodea plants was reduced, the number of bubbles would choose... decrease increase stay constant

Explanation:

Bubbles are produced as a result of oxygen being released during photosynthesis by Elodea plants. Fewer plants mean less photosynthetic activity and thus fewer oxygen - producing sites. So, the number of bubbles would decrease.

Answer:

decrease
