Hello. This question is incomplete. The full question is:
" Which of the following terms refers to bloodstains that are not visible to the naked eye? A. molded bloodstains B. hemoglobin C. latent bloodstains D. blood spatter"
Answer:
C. latent bloodstains
Step-by-step explanation:
Latent blood stains are not visible to the naked eye. For this reason, within the forensic science there are methods and equipment that can be used so that this type of blood stain can be visualized. The well-known luminol is one such method. Luminol causes a chemiluminescent reaction in contact with the blood stain and exposed to ultraviolet light. This reaction occurs due to the affinity between the iron molecules present in hemoglobin and luminol. Blood stains are photographed and samples are collected and sent to the laboratory.
