With a diameter of 220 nanometers, the measles virus is about 8 times smaller than E.coli bacteria.
At 45 nm, the hepatitis virus is about 40 times smaller than E.coli.
For a sense of how small this is, David R. Wessner, a professor of Biology at Davidson College, provides an analogy in a 2010 article published in the journal Nature Education: The polio virus, 30 nm across, is about 10,000 times smaller than a grain of salt. Such differences in size between viruses and bacteria provided the critical first clue of the virus' existence.

What are the differences between a virus and a eukaryote?
a virus has no membrane bound organelles,whereas a typical eukaryotic cell has membrane bound organelles such as mitochondria. A virus destroys a cell by replicating itself and assembling new viruses inside the host cell until it bursts, releasing hundreds of new viruses
How do virues reproduce?
A virus needs a host cell to reproduce, so it enters a host cell(living cell e.g bacteria) and releases genatic materials which enslave the the cell and reproduce.
Why is a virus a prokaryote?
No.The prokaryotic cells are the bacteria and the archaea.The structure of a virus does not qualify it to be classed as a cell of any kind. It consists of some genetic material, either RNA or DNA, encased in protein. There are no typical cellular features such as a plasma membrane or cytoplasm.
How does your body benefit when a white blood cell kills a cell that has been infected by a virus?
Your body benefits when a white blood cell kills a cell that has been infected by a virus because the cells that was infected is no longer able to infect other cells with the bacteria. If the cell is not killed the virus in the cell will infect other cells. this may cause diseases that can be life threatening.
Single-celled organisms that do not have a membrane-bound nucleus?
Bacteria lacks a nucleus but have a fully developed DNA, thus they can be considered full cells. Virus also lack a nucleus, but they have not a fully developed DNA. Even virus having RNA only exist. For this reason virus are somehow in between cells and simple multiple molecular systems.
What does a typical virus cell look like?
A virus is a relatively long molecule, not a cell.
Can bacteria get a viris?
yes bacteria can get a virus. A virus is a pathogen that invades the host cell, changing the make up the bacteria.
What cell is smaller a virus cell a bacteria cell or a yeast cell?
The YEAST cell is by far the biggest cell out of a BACTERIUM and a VIRUS.... I know this 'cos it was on my science homework and 'cos i found it on another website which gave me the urge to put it here since the question hadn't been answered....x
What is bacteriphages?
Virus that infects a bacteria cell
Does a bacteria cell use a messenger?
no they do not a virus use a messenger and virus can give you the flu and colds
Which oif these is the smallest microscopic object a virus or amoeba or bacteria or human skin cell?
Virus
Type of wall surrounding a typical bacteria organisms?
Cell wall.
What is the structural difference between a virus or bacteria?
Bacteria are living cells -- cell membrane and all that cell stuff. A virus doesn't own it's own cell; it invades a cell and takes over, using the host cell to make more viruses.
What is the function of a cell wall in a cell?
it protects the cell wall from any bacteria virus, and other enffections
Is Ebola a bacteria fungus or bacteriaor virus?
It is not. HIV is a virus. It has a completely different make-up from a bacteria. The most important difference between a bacteria and a virus is that a virus does not have the ability to replicate on its own. It needs a host, another cell, to reproduce, unlike bacteria which can reproduce on their own.
How do cells respond to a bacteria or virus?
If a virus enters a bacteria cell, the virus will try to infiltrate the cell's central code. If the cell catches it in time, it may be stopped (like a disease virus), but many times the bacterial virus will reproduce inside the cell. Hidden virus will become part of the cell's genetic material code upon entering, and will eventually reproduce. Active virus are easier to spot, as they try to start reproducing after "laying eggs" getting inside the cell.
What is the function of the cell wall in the cell wall?
it protects the cell wall from any bacteria virus, and other enffections
