What is the general name for a substance that changes colour in acids or bases?*1 pointbromothymol bluelitmusuniversal indicatorindicator

The pH indicator bromothymol blue is blue in an alkaline solution and yellow in an acidic solution. A slight increase in acidity, such as when CO2 gas is added, causes a solution with the indicator to change from blue to yellow.A solution with the indicator would turn from blue to yellow when which combination of factors exists? Select the two correct answers.A.Algae in the solution are placed under a bright light.B.A water plant in the solution is placed on a sunny windowsill.C.A person blows air into the solution through a straw.D.Yeast cells and sugar are placed in the solution.

A bacterial cell was cleverly edited to produce the marker green fluorescent protein if exposed to a toxic chemical. Now, if the bacterium is placed into a media containing the toxic chemical, it fluorescences green. How would you name the network that is underlying the process?
