brown color
If semen fertilizes a woman's egg, the result of the test would turn from negative to positive. Otherwise, the presence of semen would have no effect on a pregnancy test.

Turns blue black
I reckon the answer would be that phenol has a hydroxyl group (-OH) which is bonded to a phenyl ring. It yields the same positive result like tyrosine which has a hydroxyl group bonded to its phenyl ring.
What is RCW, in blood test.
yes
A test for the presence of oxygen for organic compounds which contain the element carbon.
Benzene is flammable so when it is ignited fire will be produced and then black soot will appear. When benzene undergoes Baeyer's test, the process is slow but it will turn brown.
nitration of the benzene ring and gives positive
No, because phenylalanine does not react with the nitric acid in this test.
A blood test for benzene is one method that might be used to determine if an individual has been exposed to benzene and how much he might have been exposed to. As benzene leaves the blood quickly, another or other tests might also be considered.
This would depend on what kind of test result is needed: a physical exam result, a school test, a blood test, etc. If it concerns a test result due to blood or other test, you can request the result from the family physician. If the test result concerns education, this is up to the teacher or professor but you can ask..
Hexane and benzene do not react in the ignition test. Only acetylene does. Acetylene has a triple bond if equivalent amount of KMnO4 is used. The equation is HCCH + KMnO4 -> HC (OH) = CH(OH).
due to extensive delocalization of pie-electrons of benzene , it do not undergoes Bayer's and bromine test. 6 carbon nuclei hold the pie electronic cloud which make it difficult for an electrophile to attack.
Yes, it would be a valid test.
