Question

some researchers want to study how bacteria reproduction is affected by temperature. the researchers set up an experiment that measures bacteria reproduction over a specified amount of time for different temperature levels. in this experiment, what is the independent variable? a time b nutrition c temperature d bacteria reproduction

Explanation:

The independent variable is the factor that the researchers manipulate or change in an experiment. Here, they are changing temperature levels to see its effect on bacteria reproduction. Time and nutrition are not the focus of manipulation in this context. Bacteria reproduction is the dependent variable as it is what is being measured and is affected by the independent variable.

Answer:

C. temperature
