______ is the act of arranging things into orderly groups based on similarities
Classification

Morphology, but now they use DNA analysts, along with other technology and morphology
The eight different levels used to classify organisms from biggest to smallest are _______
Domain, kingdom, phylum, class, order, family, genus, and species.
Organisms are named by using the _______
Binomial nomenclature
What are the rules of the binomial nomenclature?
First name is always the genus, must begin with capital letter
second name is the species, never capitalized
if handwritten, both genus and species must be underlined
if printed or typed, both genus and species should be italicized
