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.
Bacteria (one of them is a bacterium) are very small organisms. They are prokaryotic microorganisms. Bacterial cells do not have a nucleus, and most have no organelles with membranes round them.Most have a cell wall. They do have DNA, and their biochemistry is basically the same as other living things.ost bacteria live in the ground or in water, but many live inside or on the skin of other organisms, including humans. There are about ten times as many bacterial cells as human cells in each of our bodies.
