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.
2. Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. 3. The three domains are the Archaea, the Bacteria, and the Eukarya.4. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.he three domains are the Archaea, the Bacteria, and the Eukarya. 4. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
