After 24 hours of incubation, the test tube with the yellow water will be more likely be produced by the sprig of Elodea and a snail. Snails will produce only
carbon dioxide, while the Elodea will produce carbon dioxide and oxygen
gas. I predict the snails and Elodea will produce more carbon dioxide, causing
the water to turn yellow.

Answer:

The correct answer is - test tube 4.

Explanation:

The sprig of Elodea produces carbon dioxide and oxygen after the incubation of 24 hours whereas the snail releases the oxygen in the test tube during the incubation period. The presence of both gases gives a yellowish color to the test tube solution.

Incubation is the process in which organisms or anything at a precise environment and temperature so it can develop properly.

Thus, the correct answer is- test tube 4.
