Problemas
A researcher finds that white bread contains more preservatives and has a higher moisture content than wheat bread. She designs a test to determine whether the type of bread, white or wheat, affects the amount of mold growth What must be done for the researcher to accurately measure the dependent variable? She will need to allow mold to grow for more days on the white bread, since it contains more preservatives to measure the dependent variable. She will need to limit the dependent variable to white bread or wheat bread need to allow mold to grow for fe fewer days on the while le bread, since it contains more presenvalives to measure the dependent variable She will need to learn how to quantitatively measure mold growth to measure the dependent variable.

Explicación
## Step 1The problem is about a researcher who is conducting an experiment to determine whether the type of bread, white or wheat, affects the amount of mold growth. The dependent variable in this experiment is the amount of mold growth.## Step 2The researcher needs to accurately measure the dependent variable, which is the amount of mold growth. This can be done by learning how to quantitatively measure mold growth.## Step 3The other options are not correct because they either limit the dependent variable to white bread or wheat bread, or they suggest allowing mold to grow for more or fewer days on the white bread. These options do not accurately measure the dependent variable.
