When collecting gunpowder residue for analysis, yes, this is an accepted test.
Biochemical analysis uses similarities in as evidence for evolutionary relationships.?
DNA sequences .
What is the strong evidence of common ancestry between the organism that share them?
Simularities in DNA sequence
How conclusive is DNA fingerprinting evidence?
DNA evidence is very conclusive and some say 99% accurate, however it is possible to challenge it based upon faulty collection and/or faulty lab techniques. All evidence can be contaminated by faulty collection and preservation methods and it leaves the evidence open to challenge. One key component to preserving any evidence is maintaining a secure chain of custody of any collected evidence. from the time of collection to the end of the case in court every movement of the evidence must be documented.
What is the most conclusive evidence used in establishing the relationship of closely related species?
Nuclear DNA measurements would be considered the most authoritative these days.
Is the test of ethyl and methyl alcohol conclusive?
The test of ethyl and methyl alcohol may provide some evidence, but it is not necessarily conclusive. Further analysis and testing could be needed to confirm the presence and differentiate between the two types of alcohol definitively.
What class of evidence is DNA?
DNA is classified as circumstantial evidence as there are a variety of scenarios in which the DNA could have been there, say at a popular pub there was a murder, a police man finds some blood on the floor which was not that of the victim; this is not conclusive as the blood could have gotten there a variety of ways.Added: In order to be admitted into evidence, as one of the qualifying exceptions of the "circumstantial evidence" rule, supporting facts and/or evidence must bolster its admission. Something more than mere conjecture must be offered in support of the collected DNA.
Biochemical analysts use similarities in what as evidence for evolutionary relationships?
Biochemical analysis uses similarities in DNA, amino acid sequences, as evidence for evolutionary relationships

What is it that makes an argument inductive?
Inductive arguments are those supposedly supported by good, but not conclusive, evidence. The idea of conclusive or demonstrative evidence goes with deductive arguments, whereas the idea of less than conclusive or demonstrative evidence goes with inductive arguments. Inductive arguments are based on probability; if the premises are true, the conclusion is probably true.
You are attempting to link an individual to a crime The only evidence you have is a tiny drop of blood How can you use this drop of blood to make the association?
The drop of blood can be analyzed using DNA testing to identify the individual's unique genetic profile. This profile can then be compared to databases of known DNA profiles to potentially link the individual to the crime scene. The more unique the DNA match, the stronger the association between the individual and the crime.
