3. What is the difference between patent, latent, and plastic fingerprints?

i studied this a dAY AGO 
1. Loop
2. Iodine fuming, nihydran, dusting
3. Patent - fingerprint created by foreign substances - visible to the eye
Patent - fingerprinted created by oils
Plastic - fingerprint that is imprinted into something.

2. Name on type of animal fiber
3. How can you tell the difference between animal and vegetable fiber with a microscope?

1. Polymerization
2. Wool
3. Not sure if there's anything that applies to all animal vs vegetable fibers, but some things like scales on animal fibers would give it away

-undergoes hydrolysis (reacts with water and breaks into acetate and sodium ions)
-creates a basic solution (some of the acetate ions will take protons from water molecules leaving hydroxide ions)
