Does influenza virus prefer dry or moist air?

Influenza virus is often more transmissible in cold, dry air because low humidity levels can weaken the respiratory mucosal lining and make it easier for the virus to infect. However, it can still spread in moist air through respiratory droplets when an infected person coughs or sneezes.


What can stress do to a virus?

Stress can make a virus worse than it currently is, and can even activate a dormant virus. A virus that is hiding and not doing anything is considered to be in what scientists call the lysogenic cycle. Stress can cause a virus in the lysogenic cycle to advance to the lytic cycle, which is the state at which the virus advances and actually takes effect.


Why is a host cell unable to make its own proteins if the invading virus replicates?

When a virus infects a host cell, it hijacks the cell's machinery to replicate its own genetic material and proteins instead of the host cell's. This often leads to disruption of the host cell's normal protein synthesis processes, which can prevent the cell from making its own proteins.


Why virus is always parasitic?

Viruses are considered parasitic because they require a host cell to replicate and reproduce. They hijack the host cell's machinery to make copies of themselves, which can harm the host cell in the process. This dependence on a host cell for replication is why viruses are often classified as obligate intracellular parasites.


Is Ebola a bacteria fungus or bacteriaor virus?

It is not. HIV is a virus. It has a completely different make-up from a bacteria. The most important difference between a bacteria and a virus is that a virus does not have the ability to replicate on its own. It needs a host, another cell, to reproduce, unlike bacteria which can reproduce on their own.

How do you make a harmless virus?

In most cases, you don't make a virus at all. But in the event that you do write a virus, the easiest way to make one that does not have any ill effects is to simply do so. Don't put any code in it that does any harm. If you can make a harmful virus, you can make a harmless one.

Where are the instructions for making new copies of a virus found?

Instructions for making new copies of a virus are found in the virus's genetic material, which contains the information needed for replication. This genetic material can be RNA or DNA, depending on the type of virus. The virus uses host cells to replicate and make new copies of itself, often causing harm to the host in the process.
