Question 1.
If the O2 and CO2 levels when one sprig of Elodea and one snail are put into a test tube with the lights on after 24 hours, Drastic changes with carbon dioxide increasing and oxygen decreasing.
So option B is correct.
Question 2.
The experiment that yielded the most ideal conditions in the test tube for the snails and Elodea sprigs is : 1 snails, 2 sprigs, lights on.
So, option B is correct.

So, option C is correct.
Question 4.
You have an Elodea sprig in a test tube containing bromothymol blue. Then you watch it for several days. The time of day at which the oxygen level in the tube be the lowest is just before sunrise.
So, option C is correct.
Question 5.
The two tubes contain bromothymol blue. The lights are on. After 24 hours, the color of the water be in tube D will be yellow.
So, Option B is correct.
What are Elodea sprigs?
Elodea sprigs are described as herbaceous perennial plants that feature dark green leaves arranged in whorls of two to seven along the stem.
In the presence of sunlight, Elodea sprigs will use carbon dioxide and produce oxygen during photosynthesis. The snail will use oxygen and produce carbon dioxide on the other.
Hence, in the given exeperiment, the interdependence of Elodea sprigs and the snail is demonstrated.
