What else can I help you with?
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
Why cant every virus infect every living cell?
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
Are viruses able to infect all cell?
No, viruses cannot infect all cells; they are specific to certain host organisms and cell types. Each virus has a specific set of host cells it can infect, determined by the presence of compatible receptors on the cell surface and the virus's mechanisms for entering the cell. This specificity means that while some viruses can infect a wide range of species, others are restricted to a particular host or cell type.
Do viruses replicate in cells of organisms?
Yes. This is the reason that viruses infect cells. The virus injects its genetic material, either DNA or RNA, which then takes over the cell's activities and turns the cell into a virus factory, causing the cell to make new virus parts and assemble them. Eventually the cell ruptures and the new viruses are free to infect other cells.
What intermediate organism can only reproduce in living cells?
Viruses are the intermediate organisms that can only reproduce in living cells since they lack the cellular machinery necessary for replication. They infect a host cell, take over the cell's machinery to replicate, and then release new viruses to infect other cells.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
What did the first viruses do?
Infect cells.
What are most viruses highly specific to the cells they infect?
somehow
Why cant every virus infect every living cell?
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
Are viruses general or highly specific to the cells they can infect?
Highly specific
What is the pathogen attacks specific cells and injects genetic materials?
Viruses attach specific cells and inject genetic material. There are viruses called bacteriophages that infect bacteria be injecting their genetic material into the bacterial host and invading their protein machinery. With animal viruses that infect animal cells (much larger than bacteria), the virus either injects genetic material OR gets into the cell whole before it begins to unleash its pathogenic effects
What infectious agent live only by invading cells?
Viruses are infectious agents that can only replicate and survive by invading host cells and hijacking their cellular machinery. Once inside a host cell, viruses use the cell's resources to produce more viral particles, which can then go on to infect other cells. This process ultimately leads to the destruction of the host cell as new viruses are released to infect additional cells.
What are viruses that infect bacteria called?
the virus that infects bacteria is bacteriophage
Where would viruses most likely grow?
Viruses can only live in living organisms (viruses themselves are not actually living). They might infect cells in our body, such as throat cells (infection of throat cells causes sore throat).
Why are most viruses highly specific to cells they infects?
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect
Do viruses replicate in cells of organisms?

The virus injects its genetic material, either DNA or RNA, which then takes over the cell's activities and turns the cell into a virus factory, causing the cell to make new virus parts and assemble them.
