    Temperature is the independent variable in this experiment

    Explanation:

    A respirometer is a tool used to calculate the rate of breathing of a living organism by calculating the amount of exchange of oxygen and/or carbon dioxide.

    When the yeast cells are given sugar in an aerobic (oxygen-containing) environment, then the yeast.

    There would be an air bubble at the tip of the respirometer, and our dependent variable is the difference in the duration of the bubble, i. e. incubate in a warm water bath at body temperature (37 ° C) for about 20 minutes.
