Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.
There could be several answers to this, but some most likely ones would be that they both: have very basic structures or can be pathogenic.
Classes Structures Subroutines Functions
All viruses have nucleic acid and a protien coat called a capsid
Neither - viruses do not eat. There are debates about whether viruses are a form of life, or organic structures that interact with living organisms.

Nope just checked
The 4 basic bridge structures are:1. Beam2. Arch3. Suspension4. CantileverBridges need this design to be safe, and good for people to use.
-to isolate and identify viruses in clinical specimens -prepare viruses for vaccines -to research in detail the viral structures, multiplication cycles, genetics, and effects on the host cells
