Answer to Question 1
Answer:
Is it blood?color testing, Hemastix, Luminol, Bluestar reageant, or microcrystalline tests
From what species did the blood originate?precipitin testing in a test tube or via gel diffusion
If the blood is human, how closely can it be associated with a particular individual?ABO/Rh blood typing and DNA profiling
Answer to Question 2
Answer should include points such as the following:
To produce antibodies capable of reacting with drugs, the analyst first combines a specific drug with a protein and injects this combination into an animal such as a rabbit. This drugprotein complex acts as an antigen, stimulating the animal to produce antibodies. The recovered blood serum of the animal now contains antibodies that are specific or nearly specific to the drug.
