What else can I help you with?
All viruses require organic material for growth?
Viruses cannot grow or replicate on their own as they lack the necessary cellular machinery. They require a host cell to replicate and produce more virus particles. Once they infect a host cell, they hijack the cell's machinery to make more copies of themselves.
Are all viruses dangerous?
Not all but some do. If a person has a contagious virus then stay away from them. Some travel only buying eating raw meat or poisoned food or dirty water. Another science question d by the wizzo!
What are the six traits of viruses?
Viruses have six traits that characterize them. They are: They can produce at a high rate, they can mutate, they are acellular, they have no metabolism, they either have DNA or RNA, and they are dependent on a host cell for replication.
Does the cell theory apply to viruses?
No, viruses do not meet all the criteria of the cell theory because they are acellular entities that cannot carry out cellular functions on their own. Viruses require a host cell to replicate and carry out their life cycle.
Where do bacteria and viruses live?
Viruses live almost everywhere around us in places such as the soil and air.Different viruses may infect plants,animals or even bacteria .Viruses try to gain access to the machinery in the cell in order to make more viruses.
Is HIV able to make copies of itself without the aid of another organism?
No HIV, like all viruses lacks the machinery for self replication. Viruses instead must infect a host cell and hijack the cell to make more viruses. In the case of HIV, it must infect a living human cell in order to copy itself.
how are new viruses produced How might this process cause harm to the infected cell?
All viruses kill they cells that they infect. If not right away then later.
Are viruses parasitic?
Yes because all the viruses uses host cell mechanisms to reproduce and then at the end of the reproduction process it destroy the host cell.Therefore there is no non-parasitic viruses.All viruses are parasitic.

Which two viruses infect all vertebrates?
The two viruses known to infect all vertebrates are the rabies virus and the influenza virus. Rabies virus, a member of the Lyssavirus genus, affects the central nervous system of mammals, while influenza viruses, particularly the types A and B, can infect a wide variety of vertebrates, including birds and mammals. These viruses have adapted to exploit the cellular machinery of diverse vertebrate hosts, showcasing their broad host range.
Do all viruses grow using sunlight and carbon dioxide?
Viruses do not "grow", much less use sunlight and carbon dioxide to develop. That is what plants do. Viruses enter a host cell, intergrate their DNA with its, and the host cell "builds" more parts of the virus, which assemble in masses, explode out of the cell, and go on to infect new host cells.
What can viruses not infect?
Proteins,carbohydrates,nucleic acid and some have Lipids.Virus are also made up of those as other animals. 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. Some naked viruses include poliomyelitis, warts, the common cold, chickenpox, shingles, mononucleosis, herpes simplex (cold sores), influenza, herpes viruses and HIV (AIDS). Some enveloped viruses include norovirus (stomach bug), rotavirus and human papillomavirus (HPV). The envelope can be damaged by freezing temperatures, chlorine, and phenol. If damaged the virus cannot infect. Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own. They are very small and can be considered ultramicroscopic. We were not able to see them with the best light microscopes as we could bacteria (prokaryotes). We have to use an electron microscope to see them as they are that small. This was not available until recently.
Are viruses a living cell?
No, they are not alive at all.
What parts of a computer do viruses infect?
Their are many parts of a computer that viruses infect. Most viruses infect a certain file or program so that whenever that file is run, the virus is also executed. Some viruses called Master Boot Record viruses infect the Master Boot Record of your computer. The Master Boot Record is the partition of your computer first executed when you boot up your computer. When you turn on your computer, it runs all the programs inside the Master Boot Record partition and then passes control to other child processes. Viruses in this class infect the Master Boot Record so that whenever your turn on your computer, the viruses runs at startup too. These viruses are very tricky to find as they hide in a very deep part of your Operating System and manually deleting them could damage your computer.
Are all viruses dangerous?
Not all but some do. If a person has a contagious virus then stay away from them. Some travel only buying eating raw meat or poisoned food or dirty water. Another science question d by the wizzo!
Is there any specific name for a helpful virus?
No. Any and all viruses are parasitic. There may not be any helpful viruses, but there are certainly a large quantity of harmless viruses, which doesn't infect humans, but rather specific animals or plants.
How many different types of viruses are in the?
There are thousands of different types of viruses that exist in the world. These viruses can infect various organisms including animals, plants, and bacteria. It is estimated that only a small fraction of all viruses have been identified and studied so far.
