The animals evolved from the habitat they live in . Because the air around them always changes.
D. all the above I just took the test for it
Phylogenetic classification has two main advantages over the Linnaean system.
-First, phylogenetic classification tells you something important about the organism: its evolutionary history.
-Second, phylogenetic classification does not attempt to "rank" organisms.
Linnaean classification "ranks" groups of organisms artificially into kingdoms, phyla, orders, etc. This can be misleading as it seems to suggest that different groupings with the same rank are equivalent.
Answer:
Shaggy black fur and large size distinguish this animal from all other Adirondack mammals. The black bear has a short, inconspicuous tail. The body and legs are short.

Explanation:
Answer:
Virus are small infectious particles which act as intracellular parasites. They are considered non-living when they are present outside their host because they show no metabolism outside.
They do not have even cellular level of organization and are basically just packages of nucleic acid and protein. Still, virus have some important features which are common with cell-based life like the presence of nucleic acid as their genetic material.
Apart from the presence of genetic material they also have the ability to evolve like the cell-based life. This evolution allows them to be selected naturally and produce more offspring.
