Question

1. dr. romano is teaching a group of police officers how to collect evidence at a crime scene. what would he most likely explain to the officers about cross - contamination? all evidence needs to be viewed by at least two officers to be verified. evidence should be separated so it doesnt transfer to other objects. it is important to put all collected evidence in the same sealed bag. only forensic scientists can truly collect evidence correctly.

Explanation:

Cross - contamination in forensic evidence collection means that evidence can transfer substances to other objects. To prevent this, evidence should be separated. Viewing by two officers is about verification, not cross - contamination. Putting all evidence in one bag increases cross - contamination risk. And while forensic scientists are trained, police officers can also collect evidence correctly with proper training.

Answer:

Evidence should be separated so it doesn't transfer to other objects.
