Biology life . It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted to future generations. Another major theme is evolution , which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move , grow, and reproduce . Finally, all organisms can regulate their own internal environments . (Full article...

Archaea ar-KEE -ə domain of organisms . Traditionally, Archaea only included its prokaryotic members, but this since has been found to be paraphyletic , as eukaryotes are now known to have evolved from archaea. Even though the domain Archaea includes eukaryotes, the term "archaea" (sg. : archaeon ar-KEE -on classified as bacteria , receiving the name archaebacteria (, in the Archaebacteria kingdom ), but this term has fallen out of use.
Archaeal cells have unique properties separating them from Bacteria and Eukaryota . Archaea are further divided into multiple recognized phyla . Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. It is unknown if they are able to produce endospores . (Full article...
Bloodroot (
Sanguinaria canadensis ) flowers are produced from March to May, with 8-12 delicate white
