The system is like a chemistry lab which breaks down complex proteins and starches into simple chemicals.

The estimated uncertainty is ±0.1 ml

Explanation:

Measurements are usually associated with uncertainty which depends on the instrument used or the procedure employed.

It is given that the graduated cylinder of volume 25 ml has a major scale marked every 2 ml and minor scale with 0.2 ml. In general measurements made with graduated cylinders can be estimated one decimal place beyond the smallest division. In this case, the volume of the liquid can be read to the nearest 0.1 division. Hence, the uncertainty would be ± 0.1 ml.
