What Is the Dependent Variable in a Yeast Experiment

The dependent variable is the value that was measured or calculated during the experiment. In this case the dependent variable was either CO2 volume (ml) or the calculated respiration rate (ml CO2/min).

What is the independent variable in the yeast balloon experiment?

Research Question:How does the type of sugar affect carbon dioxide production in yeast?Safety Concerns:Materials may be hot, use oven mittsIndependent variable: Type of sugar Dependent variable: Circumference of balloonControlled variables: Heat of test tube Amount of water Amount of yeast

What is the independent variable in measuring CO2 production in yeast?

The independent variables are temperatures of 10% glucose solution in which yeasts are placed to carry out aerobic cell respiration. They are 6°C, room temperature, and 30°C respectively.
