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
Does hand sanitizer kill all viruses?
Hand sanitizer is effective against many viruses, particularly enveloped viruses like the flu and coronaviruses, when it contains at least 60% alcohol. However, it does not kill all viruses, particularly non-enveloped viruses like norovirus and some strains of adenovirus, which are more resistant to alcohol-based sanitizers. Additionally, hand sanitizer may not eliminate all types of germs, especially if hands are visibly dirty or greasy. For comprehensive protection, washing hands with soap and water is recommended.
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.
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 plant contains both male and female reproductive structures?
All plants contain male and female reproductive structures
What 2 structures do all viruses have?
All viruses have nucleic acid and a protien coat called a capsid
What are the three main microbes in science for age 11-14?
25
What a three main types of micro-orgismis?
The three main types of microorganisms are bacteria, viruses, and fungi. Bacteria are single-celled prokaryotic organisms, viruses are non-living infectious particles, and fungi can be single-celled (yeast) or multicellular (mold). All three play important roles in various ecosystems and can have both positive and negative effects on human health.
What are the two structures that all viruses have in common?
RNA (Ribo-nucleic Acid) and a Protein coat called the capsid.
What characteristic applies to all three domains and viruses?
They have genetic material. (Novanet)
What structures are found in all viruses?
All viruses contain genetic material (DNA or RNA) and a protein coat (capsid) that surrounds and protects the genetic material. Some viruses also have an outer lipid envelope that is derived from the host cell membrane.
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 main structures do all specialized cells have?
DNA and a cell membrane and cytoplasm
Are viruses living structures based on the 7 properties of life?
Viruses are not considered living structures because they do not exhibit all the properties of life. While they can replicate and evolve, they lack the ability to carry out metabolic processes, respond to stimuli, or maintain homeostasis independently. Viruses rely on host cells to reproduce, making them dependent entities.
What three structures are found in all mammalian cells despite three billion years of evolution?
The three structures found in all mammalian cells are the cell membrane, cytoplasm, and genetic material (DNA). These structures play essential roles in maintaining cell function, structure, and genetic information across all mammalian species.
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.
Where should you store data to stop viruses?
To keep viruses from infecting data, keep a copy on an external hard drive that is disconnected from the main computer at all times (except when you are copying over files).
