Numerical taxonomy for bacteria requires a that the tests us

Numerical taxonomy for bacteria requires: (a) that the tests used have a clear positive or negative outcome. b) that the results can be compared to the results on the same test for an organism whose name is known, (c) that the share and gram stain of the organisms is known, (d) that the laboratory has access to instruments that will allow rapid testing of multiple factors, (e) A, B and D, (f) A, B, and C, (g) B, C, and D.

Solution

The answer is b)that the results can be compared to the results on the same test for an organism whose name is known because numerical taxonomy involves the grouping of taxonomical units based on character states.These states are shown by the tests done on a known organism and we can compare the results with other organisms and perform this.
