An uncontaminated sample is known as a substrate control.  

<u> </u><u>Explanation:</u>

During the investigation of a crime scene, the forensic scientist collects a sample. This sample helps the forensic scientist to have a better understanding about it.  

A substrate control comprises of uncontaminated surface material near a region where physical proof has been saved. This example is to be utilized to guarantee that the surface on which an example has been stored doesn't meddle with research center tests.

Also, this sample ensures that the surface where the sample has been collected does not interfere with the lab test. The substrate controls enable the background reading about the stained sample.

Which section of a lab report would most appropriately contain the possible sources of error in an experiment?
Vlad1618 [11]

The lab report contains the theory, process, data and calculation of the experiment. The theory and process are remains fixed for a particular experiment. Thus there is no chance to get error from these two part. The calculation depends upon the reading or data of the experiment. The calculation is also unique and based on the data. Thus the error come from the data of the experiment. As for example for a titration experiment the data recorded in the process from the burret is the source of error, on which the calculation depends.
