Question

Dried seminal stains from clothing are preserved in how much percentage of formalin

Answer 1

Answer:

Blood is a common type of evidence and this evidence should never receive exposure to intense heat or humidity. In fact, it should be refrigerated until it is brought to a crime laboratory.

Blood might be lifted by tape or it might be scraped and then preserved on a cotton square. Blood can also be absorbed onto threads. Evidence items that are bloodstained may be packaged into a bag or envelope to prevent contamination with another piece of criminal evidence or surrounding objects.
