Viruses (biological)

A virus is a small infectious agent that can replicate only inside the living cells of organisms. Viruses display a wide diversity of shapes and sizes, called morphologies. Generally viruses are much smaller than bacteria. Most viruses that have been studied have a diameter between 10 and 300 nanometres.

How do virus propagate?

Viruses replicate by hijacking a host's cells. The virus inserts its own RNA sequence into the host cell's nucleus, forcing it to replicate the virus until the host cell dies.

How long can hiv virus live in open air?

The length of time that cold or flu germs can survive outside the body on an environmental surface, such as a doorknob, varies greatly. But the suspected range is from a few seconds to 48 hours - depending on the specific virus and the type of surface.

Flu viruses tend to live longer on surfaces than cold viruses do. Also, it's generally believed that cold and flu viruses live longer on nonporous surfaces - such as plastic, metal or wood - than they do on porous surfaces - such as fabrics, skin or paper.

Would it be so bad if the Coronavirus wiped out 1-2 billion people?

Yes because many families would be hurt. Also, probably every family in the world would suffer but it is not really possible because it only kills people with low immunity.

Does mocospace have viruses?

I got a worm (virus) on my computer from mocospace a while ago. I had to get a new computer. My friend had also gotten a worm from it on her lap top, but that's just our experience with it. We found out that using mocospace through a phone doesn't give off any virus that we know of, just when you go on it through a computer.

-----

I also got a virus as well using mocospace. Regardless of what browser you are using if your on a PC chances are you will get a virus using mocospace. It seems that the virus is coming from the chatroom. You don't have to replace your computer, you simply need to remove the virus with a program called malwarebytes. Its a free download but the trick is getting it to run before the virus takes over your antivirus program.

Is influenza photosynthetic?

No. Influenza (flu) is caused by a virus. Virus particles are not living organisms, they are sub-microscopic particles that are held in a protein package/envelope and contain DNA or RNA that is used to hijack a host animal's cell that they make do the replication for them using the host's cells' energy and materials. They hijack the cell by inserting their DNA/RNA into the host cell and that converts the cell into a virus-producing "factory". Viruses do not have or need their own energy, so they have no need for photosynthesis or food to produce their own energy.

Does the Flu Nasal Spray Flu mist hurt?

No.

The mist vaccine isn't supposed to hurt, and it didn't hurt when I got it. However, it will catch you off guard, even when they tell you they are about to spray it. It took my breath away when it went in, and it feels funky. There definitely was no pain, though.

What two things are viruses typically made of?

Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.

Who recovers more quickly from the flu someone who had a flu shot or someone who had no flu shot and why?

  • eastern equine encephalitis (EEE)
  • western equine encephalitis (WEE)
  • Venezuelan equine encephalitis (VEE)

Does bacteriophage feed on bacteria?

Yes, that is the meaning of the name " bacteriophage. " " bacteria eater. " Though they hijack the metabolic and replicative process of bacteria to replicate themselves and not actually eat the bacteria.
