Is a host a living thing as in cells?
Yes, the host is living, whether it be a host for a virus, a worm, or a bacterium.
Where in a host cell does hidden virus hide while it is inactive?
bacterium
What is a disease producing agent especially a virus or bacterium called?
A micro-organism, such as a bacterium, a virus or a fungus, that invades a host and causes a disease is called a pathogen.
How long do viruses to reproduce?
When its host cell makes more copies of the virus
What role does a host cell play the formation of a virus?
reproduction engine
Small doesnt grow requires a living host for reproduction?
virus
Which type of virus reproduction results in the death of the host cell?
lytic cycle
What does a virus do to its host cell?
virus want to the enzymes of their host cell for grow and reproduction so it take many enzymes which want o the host cell.
What uses an infected host cell's genetic and metabolic machinery for reproduction and assembly?
a virus
What is an organism that may limit the growth rate of an organism?
Pathogens such as a bacterium or a virus can influence the growth rate of the host organism. Virus (not really an organism) can infect a bacterium and integrate their genetic material. This changes the homeostasis of the bacteria, because viral proteins would be start producing by the host. hence the host can not grow as a normal organism after infection.
When a virus invades a host the most common threat is?
destruction of cells by viral reproduction
How do hidden viruses multiply?
1. A virus attaches to a bacterium. 2. The virus injects its genetic material. 3. The genetic material of the virus combines with the bacterium's genetic material. 4. The virus's genetic material detaches from the bacterium's genetic material and the bacterium produces the virus's proteins and genetic material. 5. New viruses assemble. 6. The bacterium bursts open, releasing new viruses.
