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.
Examples of Prokaryotes. Prokaryotes are all single-celled organisms, most of which you know of as bacteria. For example, the famous (or infamous) Escherichia coli bacterium is a prokaryote, as is the streptococcus bacterium responsible for strep throat. prokaryote is a cell without a nucleus and eukaryotes are cells that contain nuclei. There's one quick test to distinguish prokaryotes from eukaryotes: if you can see a single organism, it's a eukaryote.
