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.

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.
Prokaryotes arose during the Precambrian Period 3.5 to 3.8 billion years ago. Prokaryotic organisms can live in every type of environment on Earth, from very hot, to very cold, to super haline, to very acidic. The domains Bacteria and Archaea are the ones containing prokaryotic organisms. The Archaea are prokaryotes that inhabit extreme environments, such as inside of volcanoes, while Bacteria are more common organisms, such as E. coli.
