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.
Eukaryotes are organisms, including humans, whose cells have a well defined membrane-bound nucleus (containing chromosomal DNA) and organelles. The division between prokaryotes and eukaryotes reflects the existence of two very different levels of cellular organization.Distinctive types of prokaryotes include extremophiles and methanogens; these are common in some extreme environments.owever, two organelles found in many eukaryotic cells, mitochondria and chloroplasts, contain ribosomes similar in size and makeup to those found in prokaryotes. This is one of many pieces of evidence that mitochondria and chloroplasts are themselves descended from free-living bacteria.
