taxonomy: the academic discipline of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. Each group is given a rank and groups of a given rank can be aggregated to form a super group of higher rank and thus create a hierarchical classification.

Atoms Have No Electric Charge Because They Each of these isotopes has a different mass, but all are sulfur because they have 16 protons. Each electron has a negative electrical charge. Electrons can move away from the atom sometimes. They. Atoms have no electric charge, because they maintain an equal number of protons (positively charged subatomic particles) and electrons, subatomic particles. These measurements made it possible to calculate a value of coulombs per gram for the ratio of the electron’s electrical charge to its mass.*. The particles

A total of 99 strains of petroleum-degrading bacteria isolated from Chesapeake Bay water and sediment were identified by using numerical taxonomy procedures. The isolates, together with 33 reference cultures, were examined for 48 biochemical, cultural, morphological, and physiological characters. The data were analyzed by computer, using both the simple matching and the Jaccard coefficients.

While several other naturalists of the early 19th century also pursued a numerical approach to taxonomy, Bronn took it further than. on the number of species or genera it contains at a given time.

Numerical taxonomy neither produces new data nor is a new system of classification but it is a new method of organizing data and obtaining from them a classification. R.H.A. Sneath or R.R. Sokal published a textbook “Principle of Numerical Taxonomy” in 1963 and revised it in 1973 as Numerical Taxonomy.

These were run in duplicate at 30 and 35°C, and the results were analyzed by numerical taxonomy. The computer-generated phenograms derived from simple matching coefficients and unweighted average.

As defined by P. H. A. Sneath and R. R. Sokal, the grouping by numerical methods of taxonomic units based on their character states. According to G. G. Simpson, taxonomy is the theoretical study of classification, including its bases, principles, procedures, and rules.

(a) Numerical taxonomy is also called phenetic or adansonian taxonomy (Adanson, 1763). Numerical taxonomy deals with statistical analysis of the traits. All the traits are given equal weightage.
