not a cell
simple containing hereditary info wrapped in a protein rely on hosts cells machinary for their activity |
|
|

|
What are the 3 primary concerns for taxonomy?
|
classification
nomenclature identification |
|
|
What is the order of taxa?
|
Did King Phillip Come Over For Good Spaghetti?
Domain Kingdom Class Order Family Genus Species |
|
|
How are organisms grouped in taxonomy?
|
According to phylogenetic similarity
based on evolutionary similarites in morphology (structure), physiology (function), and genetics (inheritance) |
|
|
Why are viruses not classified with everything else?
|
THey are not cells and they are not alive and we just don't know where to put them exactly
