The factor that was allowed to change during Emily's experiment was the temperature of each incubator.
<h3>What is peroxisomes?</h3>
Peroxisomes are organelles located in the cytoplasm of eukaryotic cells <u>responsible for the oxidation and elimination of hydrogen peroxide</u> as in the experiment. These also have functions related to lipid metabolism and converting reactive oxygen species.
The formation of peroxisomes occurs by division of existing peroxisomes or by generation of new peroxisomes from the endoplasmic reticulum and mitochondria.
As for the experiment, we see that factors such as the amount of sulfuric acid added, the time in which each tube is equilibrated, the amount of hydrogen peroxide in each tube and the amount of catalase added are measured and do not change during the experiment while emily does give a space for the temperature of the tubes to change at their own mercy, <u>this being a variable that is not measured</u>.
Therefore, we can confirm that the factor that was allowed to change during Emily's experiment was the temperature of each incubator.
