Numerical identification methods rely on a series of which kind of tests to identify microorganisms?

Numerical identification methods rely on a series of biochemical testing to identify microorganisms.
These tests are used to identify bacteria and other microorganisms. ELISA tests are used to find antigens. DNA base composition obviously has to do with DNA, as well as DNA fingerprinting. Thus, this leaves us with biochemical testing as the correct answer.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
