Question

check my work?

In a lab experiment placed Elodea (a water plant) and snails in a test tube with a chemical which turns colors based on the presence of carbon dioxide. The test tube was placed under light for 24 hours. See the set up below:

Choose the statement below that best explains the results you observed from this lab:

In the test tube containing both snails and Elodea under the light, the solution was:

green because the carbon dioxide produced by Elodea and snails through cellular respiration is taken out through Elodea's photosynthesis, so it doesn't build up but there is still a little left from the control group.

blue because the carbon dioxide produced by Elodea and snails through cellular respiration is taken out through Elodea's photosynthesis, so they balance each other out.

yellow because Elodea can't perform photosynthesis and both Elodea and snails are going through cellular respiration, causing carbon dioxide to build up.

green because Elodea and snails are both going through photosynthesis and produce carbon dioxide.<<<

Answer 1

yellow because Elodea can't perform photosynthesis and both Elodea and snails are going through cellular respiration, causing carbon dioxide to build up.
