prokaryotes
what is the hierarchal classification?
kingdom phylum class order family genus species
how do we remember the hierarchal classification (acronym)?
king phillips cat ordered fresh greek salad
as we move down the hierarchies, what happens?
characteristics become more similar
what happens in a smaller (lower) taxa?
there are more similar organisms
