Fish And Cellular Respiration Lab HELP Cellular Respiration & Photosynthesis Lab Question?? Pleasee?

HELP cellular respiration & photosynthesis lab question?? pleasee? - fish and cellular respiration lab

An experiment was developed by the students of biology, to demonstrate the relationship between photosynthesis and cellular respiration. Bromothymol blue (and the display changes from blue to yellow used in the presence of carbon dioxide) was the carbon dioxide is formed when high concentrations of carbon dioxide combines with water. The following tests were created;

# 1 - 50 ml of distilled water and 3 drops of bromothymol blue were placed in a test tube.
Ml # 2 - 50 of distilled water, 3 drops of bromothymol blue and Guppy fish were placed in a test tube
Ml # 3 - 50 of distilled water, 3 drops of bromothymol blue and water plant were placed in a test tube
Ml # 4 - 50 of distilled water, 3 drops of bromothymol blue, guppy fish and aquatic plants were put into a test tube

The original color was blue in all the test tubes

A - identify the control, independent and dependent variables of the experiment

B - Forecast changes the color in each tube and supporting a cause, their forecasts.
