A student places four small aquatic snails in a test tube containing bromothymol blue solution. The solution will change color from blue to yellow if the carbon dioxide level increases. The student seals the test tube and notes that the solution is blue. After a few hours, the student observes that the solution is yellow. What cellular process did the snails perform that caused the color of the solution to change

Respuesta :

Answer:

Respiration.

Explanation:

Respiration is the process which occurs in the test tube because the snails is a living organism that releases carbondioxide gas that mix with the solution and change the colour. The student says that the solution will change color from blue to yellow if the carbon dioxide level increases. So due to presence of living organisms in the test tube, the living organism provides carbondioxide in large amount through the process of respiration.
