Answer:
Activity level of 3
Step-by-step explanation:
To evaluate the enzyme activity you might observe the amounts of starch remaining in a solution or the enzyme activity. Both of them can be done qualitatively by adding substances such as iodine to the sample, which will express, through different degrees of the blue color, the enzyme activity level. So,
no enzymatic activity ----------------> level 0
low enzymatic activity ---------------> level 1
moderate enzymatic activity ------> level 2
High enzymatic activity --------------> level 3
