Assume that you have an unknown solution in a test tube. When you add phenol red to the test tube, it immediately turns pale yellow. This is an indication that the solution in the tube:

Fermentation in yeast can occur without:

A student conducted an experiment where she ground up different antacids and mixed them with water and a drop of phenol red (a pH indicator), then added drops of HCl (acid). She observed how many drops of acid it took to change the color of the phenol red from red to yellow.What is the independent variable in this experiment?
