You will have to either be more specific about what you want to find out, or narrow your subject field down a little. There are entire textbooks written on this subject and which contain more material than can possibly be covered here.
evidence
In certain cases in could but in a general term no it cannot, poorly collected evidence could contaminate it or even if obtained wrong could be thrown out and not be used as evidence that is why there are procedures to be followed.
Variables
a questioned specimen is evidence collected at the scene of the crime and a known specimen is something from a known person or source.
Controlled evidence refers to information or data that is collected under specific conditions that minimize variables and biases, ensuring reliability and validity. This type of evidence is often used in scientific experiments and research studies, where researchers control factors to isolate the effects of a particular variable. The goal is to produce replicable results that can be confidently used to support conclusions or hypotheses.
Where is Physical Evidence found and collected?

They cannot retry! Evidence is sometimes wrong!Added: If evidence is not completely, properly and thoroughly collected or processed, and documented it is subject to being challenged by the defense which might throw its reliability into question.

An evidence log is a document that records detailed information about each piece of evidence collected at a crime scene, including description, location, date, time, and by whom it was collected. It is used to maintain a chain of custody, ensure the integrity of the evidence, and provide documentation for legal proceedings.
Paint evidence can be collected using methods like tape lifting, scraping, or swabbing. The collected samples are typically placed in airtight containers to prevent contamination and stored in a secure location to preserve their integrity. Preservation also involves documenting the collection process thoroughly to maintain a chain of custody and ensure the evidence's admissibility in court.
Variables
It is called "processing"
