After conducting the experiment with the first sample, it is necessary to perform two more replicates of the same sample because:

A. The saline solution may deteriorate between one sample and another.
B. The titrated samples must have different characteristics.
C. It is necessary to check the results obtained in order to avoid any errors.
A. The physiological saline may deteriorate between one sample and another.
B. The titrated samples must have different characteristics.
C. It is necessary to check the results obtained in order to avoid any errors. Doing the test with only one sample implies the risk of some error occurring during the procedure; thus, with the realization of replicates, the chance of obtaining a more precise and accurate result is increased.
