The very first virus discovered was in 1892 by Dmitri Iwanowsk. While studying mosaic tobacco disease, he found that the agent causing the disease was small enough for pass though ceramic filter that are small enough to trap all bacteria. This was not called a virus at the time.

Why do scientist not know how many viruses there are?
Scientists do not know how many viruses there are because new ones are constantly being made from old ones joining.
Scientists first learned about reproduction in viruses by studying what?
Scientists first learned about reproduction in viruses by studying the bacteriophage, a virus that infects bacteria. The bacteriophage lifecycle involves attachment, penetration, replication, and release of new viral particles, providing insight into how viruses replicate. This research has been pivotal in understanding the mechanisms of viral reproduction and in developing antiviral strategies.

Why did scientists start studying viruses?
Scientists began to study viruses because they had found a factor that was smaller than bacteria but could still cause diseases. This factor came to be known as a virus. At that time, they didn't have the technology to see viruses. But they wanted to know if viruses were very small cells or simply non-living groups of molecules.
Scientists hope to be able to use viruses for gene therapy because viruses can what?

Why are scientists unable to tell how many different viruses there are?
There are an estimated 320,000 mammalian viruses alone, and this number is constantly growing as new viruses are discovered. Viruses are diverse, constantly evolving, and have the ability to jump between different host species, making it challenging for scientists to accurately count and categorize all virus species. Additionally, many viruses remain undiscovered in the natural world.
What caused scientists to begin studying viruses?
there families
What characteristics do scientists use to classify viruses?
their genome
How do you know cuneiform in the first place?
because scientists discovered it.
How and why do scientists know when the first day of fall is?

Can viruses be modified to undo damage by other viruses?
Some scientists are hoping that viruses can be modified to undo damage by other viruses, but there is no actual working "damage control" virus available as of July of 2013. Many scientists are concerned that even the good virus might have unwanted side effects.
Why do we study viruses?
Viruses have the ability to greatly affect life on earth. Many viruses, such as HIV and influenza have killed millions of people. By studying viruses, scientists are able to develop vaccines that will protect people (and animals) from viruses.
