Why aren't viruses considered living things?
They aren't made of cells
They don't have DNA or RNA
They make us sick
They are made of protein
Viruses can only reproduce with the help of a (a) cell. This is another reason that viruses are not considered (b) things.
When a virus takes over a cell, it can cause the cell to create many more copies of the virus until the cell bursts open and releases them. What part of the virus's lifecycle is this?
Lytic
Lysogenic
Unlike (a) , viruses cannot reproduce on their own. Viruses need a (b) cell to reproduce.
If someone is sick with a bacterial infection, they may be given (a) . That doesn't work if you are sick with a (b) , because viruses are not alive.
A virus is bigger than a cell.
True
False
How are virus' like living things?
both made of cells
both contain DNA
What type of virus starts replicating right away, as soon as its DNA enters the host cell?
hidden virus
active virus
a very bad virus
When a virus takes over a cell, it can cause the cell to create many more copies of the virus until the cell bursts open and releases them. What part of the virus's lifecycle is this?
Lytic
Lysogenic
