Because there's a chemical reaction going on.
With the flame test we can identify some chemical elements; see the link to Wikipedia, for ex.
biologist used aqueous solution to perform chemical test as this solution behaves as the medium for chemical reaction and is also the medium of chemical reaction in living beings so that is why biologist use aqueous solution.
Due to electron transitions in atoms some chemical elements emit a characteristic colored flame.

glowing splint ... if it relights then the chemical reaction produces oxygen.
There is no chemical or physical reaction in this test.
The only way to be sure a chemical reaction or change has occurred is to test the composition of a sample before and after a change.
chemical reaction
A precipitate is formed.A precipitate (sediment) is formed.
the process goes on faster like in a chemical reaction

Reagent bottle is a bottle designed to contain chemical reagents. Bottles are made generally from glass, plastic coated glass, polyethylene. The volumes are extremely variable, from 1 mL to liters.
A mononucleosis test? No. It tests a different set of chemical levels in your body. Try an over-the-counter test.
