Ninhydrin causes prints to turn a purple color, which makes them easily photographed. DFO (1,2-diazafluoren-9-one) is another chemical used to locate latent fingerprints on porous surfaces; it causes fingerprints to fluoresce, or glow, when they are illuminated by blue-green light.
Explanation:
I believe the answer to this is Fermentation and anaerobic respiration.
Carbon-14 is the radioisotope that is used to determine the age of once-living organisms. Radioactive dating is a technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material. The mostly used radioisotope is carbon-14, because may rocks and organisms contain this radioisotope.
Hey there!
We need to find a common denominator.
5*3= 15
4/5= 12/15
2/3= 10/15
12+10=22
22/15
or
1 7/15
I hope this helps!
