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 Archaea (/ÉËrËkiËÉ/ or /ÉËrËkeÉªÉ/ ar-KEE-É or ar-KAY-É) constitute a domain and kingdom of single-celled microorganisms. These microbes (archaea; singular archaeon) are prokaryotes, meaning they have no cell nucleus or any other membrane-bound organelles in their cells. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this classification is outdated.
