Employability skills are generally divided into three skill sets: (a) basic academic skills, (b) critical thinking skills and (c) personal qualities. The three skill sets are typically broken down into more detailed skill sets.
In the past Archaea were classified as an unusual group of bacteria and named archaebacteria, but since the Archaea have an independent evolutionary history and manifest numerous differences in their biochemistry from other forms of life, they are now classified as a separate domain in the three-domain system.
The genetic analysis shows that similar miniaturized eukaryotes branch from all the groups in the phylogenetic tree. Microbes include members of the three domains of life. The three domains of life are bacteria, archaea and eukarya. Out of the two prokaryotic cells are considerably simpler than eukaryotic cells. Bacteria and archaea are considered prokaryotes. Prokaryotic comes from the Greek prefix pro which means before and the Greek root karyon which means kernel. They tend to be smaller in size and are not as complex as eukaryotic cells.
