When should you identify root causes? 1  Whenever you are faced with addressing a challenging community problem. 2  When there is support for a solution that does not seem to get at the real causes of the problem. 3  When there is ignorance or denial of why a community problem exists.
There are two basic types of organisms based on cell type: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into the domains Bacteria and Archaea. Eukaryotic cells make up the more familiar Domain Eukarya. Prokaryotes are the smallest forms of life that can live independently. Most prokaryotes are tiny single cells, but some can form larger, multi-celled structures.
The division between prokaryotes and eukaryotes is usually considered the most important distinction or difference among organisms. The distinction is that eukaryotic cells have a true nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus.
