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 (singular: bacterium) are single-celled organisms which can only be seen through a microscope. They come in different shapes and sizes, and their size is measured in micrometer-which is a millionth part of a meter.here are several different types of bacteria, and they are found everywhere and in all types of environment. There are various groups of bacteria, which belong to the same family and have evolved from the same bacteria (ancestor).
