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.
A virus can have one of three structures. These are:
Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus.
Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
Polyhedral virus.

What are the two main categories of science?
don't you mean three? Biology Physics and chemistry and in my opinion they are all equally important
Scientist who studies viruses?
Virology is the study of viruses and their evolution, structure, classification. It also is complexes of nuclies acids and proteins that help all living cells.
What plant contains both male and female reproductive structures?
All plants contain male and female reproductive structures
Which is difference between bacteria and viruses that shows that bacteria are living organisms and viruses not?
Bacteria are able to reproduce on their own while viruses need a host to "hijack" so they can reproduce. Bacteria have metabolisms, catabolic and anabolic biochemical reactions going on in their cells all the time. Viruses do not. Bacteria can grow in size to a certain extent while viruses do not change in this regard. The definition of living things classify bacteria as a living thing, while viruses are not.
What aspect of the structure of viruses is similar to all living things?
Presence of nucleic acid.
What 2 structures do all viruses have?
All viruses have nucleic acid and a protien coat called a capsid
What structures are found in all viruses?
protein coat and nucleic acid
What are the three main microbes in science for age 11-14?
25
What three structures that most likely found in all fish?
Three structures that are most likely found in all fish are: gills, fins, and blood.
What are the two structures that all viruses have in common?
RNA (Ribo-nucleic Acid) and a Protein coat called the capsid.
List the main types of computer viruses?
Trojan- A horse that infects the computer Worm- Makes computers stop Cakes- A type of infection that makes your computers stop from downloads Bug- Bugs that store and infect in your computer
What characteristic applies to all three domains and viruses?
They have genetic material. (Novanet)
What main structures do all specialized cells have?
DNA and a cell membrane and cytoplasm
What are the three main ideas behind cell theory?
All living things are made up of cells Cells are the basic units of functions and structures in all living things and Living cells come only from other living cells.
What is the structure of a virus like?
Viruses are ranges in different sizes and structures. HIV, HBV, influenza are all spherical in shape. Phages like T phages carry an icosahedral structures. M13 phages, ebola appear as hair like (or tube) structures. TMV appears as rod like structure.
Is a dolphin segmented?
A dolphin is not looked at as segmented. This is because all of the main structures run together on the body.
What three structures are found in all mammalian cells despite three billion years of evolution?
Cytoplasm nucleus cell membrane
