It literally means âby way of e-mailâ which probably doesnât help either. In the âold days,â paper letters could be sent via courier, via air mail. It simply means e-mail was involved.
Taxonomy. Bacteria are members of the prokaryote group. In contrast to eukaryote cells, bacteria lack a cell nucleus and customarily have no organelles. The bacteria domain can be grouped into two major categories: (a) Eubacteria and (b) Cyanobacteria.here are approximately 50 million bacterial organisms in a single gram of typical surface soil. The worldwide bacterial biomass exceeds that of all plants and animals on Earth. However, the majority of bacteria have not yet been characterised.
Photo by: Sebastian Kaulitzki. Bacteria are microscopic organisms that comprise the domain Eubacteria. A domain is the highest grouping of organisms, superseding the level of kingdom in the classical Linnaean system of biological classification.here are three domains, two of which, Eubacteria and Archaea, are composed entirely of prokaryotic organisms; the third domain, Eucarya, encompasses all other (eukaryotic) life forms, including the single-cell and multicellular protists, as well as animals, green plants, and fungi.
