Question

Respirometers were set up that contained yeast and 2% glucose solution. Each respirometer was placed at a different temperature. The height of the bubble contained in the respirometer was measured every 5 minutes for 20 minutes. What is the independent variable in this experiment?

Answer 1

Temperature is the independent variable in this experiment

Step-by-step 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.
