Why are boiled beans used as a control in an experiment?

Boiled beans are often used as a control in experiments to provide a baseline for comparison because they are non-viable and have been rendered inactive through the boiling process. This allows researchers to isolate the effects of the experimental variables by ensuring that any observed changes are due to those variables rather than any inherent characteristics of the beans. Additionally, using boiled beans helps to eliminate variability related to growth or metabolic processes, ensuring more accurate and reliable results.
