Because of spironolactone's antiandrogen effects, it can be quite effective in clearing severe acne conditions, such as cystic acne, caused by slightly elevated or elevated levels of testosterone in women. In reducing the levels of testosterone, excess oil that is naturally produced in the skin is also reduced.
The prokaryotes are divided into two domains: the bacteria and the archaea. They also have a cell wall, eukaryotes do not. Prokaryotes are organisms that lack a cell nucleus or karyona or organelles. Most prokaryotes are unicellular, wheareas eukaryotes are always multicellular. Among the prokaryotes, you can find the bacteriae and the archae.
A eukaryote is an organism with complex cells, or a single cell with a complex structure. In these cells the genetic material is organized into chromosomes in the cell nucleus. Animals, plants, algae and fungi are all eukaryotes. There are also eukaryotes amongst single-celled protists. In contrast, simpler organisms, such as bacteria and archaea, do not have nuclei and other complex cell structures. Such organisms are called prokaryotes. The eukaryotes are often treated as a superkingdom, or domain. Eukaryotes evolved in the Proterozoic eon.
