Yes,they live in hosts only to reproduce.
Viruses that enter a cell do not die. A virus cannot reproduce on its own so it needs to find a cell in which to live. After the virus is done reproducing, most host cells die.
Viruses are microorganisms unable to live on their own, i.e can only live and reproduce in a living cell.Once they infect a new cell,they take over the entire cell machinery and when released,they kill the infected cell.So,viruses reproduce in Living cells. It's been cedrikstorm,garvey02@yahoo.com
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
Viruses cannot live or breed on their own. Instead, they infect the cells of living organisms, such as animals, plants, and bacteria, to replicate and spread. Once inside a host cell, the virus hijacks the cell's machinery to reproduce more viruses.
In terms of what ? I u are asking about bacteria in terms of viruses Bacteria are living and can reproduce themselves While viruses are ghosts they can only live inside a host and also can reproduce inside it Hope i answered u
Because viruses need a live host in order to reproduce. Viruses are obligate intracellular parasites. Therefore, they cannot reproduce outside their host cell, and therefore die out. They are diffcult to culture because you need something living in order to culture them in, and see the progress.
In the US there is a flu vaccination made with live viruses that have been weakened (attenuated) to prevent them from making otherwise healthy people sick. This type of vaccine can be used by those who are healthy and aged 2 - 49. It creates a very good immune response to cause immunity and so it can be administered in an intranasal mist that is inhaled into the nose instead of having to be given in a shot. The vaccines for flu that are made to be injected in a shot are made from "dead" viruses or pieces of dead viruses. So flu vaccinations are produced from both "dead" viruses and live viruses.
Because viruses are considered nonliving and they need a host to reproduce, therfore they cannot live on their own. Now bacteria can reproduce asexually, so they can get bigger and do not need a host..
a host Cell
A Virus must invade a host cell in order to reproduce. What people commonly mix up with them is bacteria which has no need to
Yes, viruses require a host in order to reproduce. They cannot replicate on their own and rely on infecting a host cell to reproduce and spread.
