Using the information below, and based on your knowledge of enzymes - which independent variable would be a good starting point to determine the cause of the poor result?

enzyme_paragraph

a
The number of people working in the factory.
b
The temperature of the wash vat where the enzymes are added.
c
The color of the jeans after the enzymes did their work.
d
The education of the quality control team.

Based on the information given and understanding the role of enzymes, the best independent variable to start with in determining the cause of the poor result would be:

b. The temperature of the wash vat where the enzymes are added.

Enzymes are biological catalysts that speed up chemical reactions and they are highly sensitive to temperature. Each enzyme has an optimal temperature range in which it is most active, and deviations from this range can lead to reduced activity or even denaturation of the enzyme, causing it to lose function. Therefore, if the temperature in the wash vat is not within the optimal range for the enzymes being used, this could negatively affect their activity and thus be the cause of the poor result in the process being examined.
