What living characteristic does a virus have?
Viruses are not alive in any sense and have no living characteristics. They are hijackers of living cells. Their DNA (or RNA) take over the cell nucleus and instead of making cell parts, the cell now makes virus parts. These parts are assembled (like building a Lego model) and when the cell is full, the cell membrane breaks, the cells dies and the viruses escape and highjack other cells. Viruses do not breathe, eat, digest, and do not have any life processes.
Which phrase describes the size of viruses particles?
The dimension of viruses is between 20 nm and 400 nm.
Can a catch catch the flu from a human?
No a catch isn't an animal or human. Humans can catch the flu and polio. A lot of kids die from polio and the flu.
How could a virus get into the nasal cavity?
A virus can get into the nasal cavity if you stick your finger in your nose or you might inhale it.
What is the difference of ssDNA and dsDNA?
ssDNA means a single strand of DNA and dsDNA is double strand of DNA. Many viruses have one or the other.
How does a virus use its host to reproduce?
The virus uses the cytoplasm from the cell it is inside to help it reproduce.
Hope this helps.
I am a sixth grade student who ironically learnt this in school today.

I take it that you meant to ask what surrounds the genome of the virus. The genome of the virus (be it DNA or RNA) is enclosed within the capsid shell. The capsid shell is made by the oligomerisation of capsid proteins in a specific organised manner. The genome together with the capsid is termed as nucleocapsid. Sometimes the nucleocapsid is surrounded by a phospholipid membrane (of host origin) called the envelope. The viruses which have an envelope are called envelope viruses eg., Chikunguyna virus, Rabies virus, HIV and the viruses without an envelope are called naked viruses eg., Poliovirus, Rotavirus
Is rabies virus a hidden or active virus?
Rabies is a virus that is hidden. If you get the rabies virus, it can be a very serious manner. Rabies can affect both animals and humans.
What is virus vaccine 3 year split?
It's a label for a CPT code that you probably found on your bill. If you Google the 5 digit code that came just before it, you'll get more info, but I think it's a flu shot.
What is the comparison between hepatitis B and C and HIV?
Transmission of hepatitis B virus (HBV) and hepatitis C virus (HCV) can occur in health-care settings from percutaneous or mucosal exposures to blood or other body fluids from an infected patient or health-care worker. They also can be transmitted by sharing needles. The hepatitis virus affects the liver. The HIV virus can be transmitted the same way but affects the entire immune system.
How to unblock ears when you have the flu?
Warning:Do not use some oil! Material: Gum,hard pillow, a shower, hard food(sallory is the best) and yourself. Tips: Try chewing gum alot and chew it on the side that your ear in blocked, also try sleeping on that same side. Try to take a shower turning your head the same way your ear is blocked Try to move your jaw a bit left and right and see whats the difrence Try to eat hard food like: Crackers,Pretzels,chips,sallery(very good)... what if it doesnt work: If nothing of those works, wait a bit(couple of hours or til when you dont have the flu anymore), and start all of those tips again. what if it stills doesnt work: If nothing happends and its been a long time you tried, go and see a doctor/specialist. Hope it works for you but it did well for me!
Viruses are unique among infectious agents because they are?
First of all, viruses are not technically living (pathogenic bacteria is). They infect by injecting a part of their DNA into the host cell which responds by producing more viruses until the host cell lyses (essentially explodes) and the viruses go on to infect other cells. The DNA injected can also remain dormant until an environmental trigger stimulates expression of the specific gene that was injected by the virus. Also viruses have no way of checking for errors when they replicate their DNA so they can easily have various mutations that allow them to respond to dangers in their environment much more easily than bacteria. For this reason, in many cases once an organism has been infected with a viral DNA it cannot be cured (examples are HIV and rabies). Vaccines help to prevent the initial infection of the host cell but can do nothing once the virus has taken hold.
In hot zone why does gene Johnson have nightmares about airborne Ebola?
Because an outbreak of a incredibly deadly virus outside of Washington D.C., killing thousands of people, would have been the most terrible thing, and it would be all on his head.
What is the role of lipid in virus?
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 lipid envelopeover 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.
Some naked viruses include poliomyelitis, warts, the common cold, chickenpox, shingles, mononucleosis, herpes simplex (cold sores), influenza, herpes viruses and HIV (AIDS).
Some enveloped viruses include norovirus (stomach bug), rotavirus and human papillomavirus (HPV).
The envelope can be damaged by freezing temperatures, chlorine, and phenol. If damaged the virus cannot infect.
Does dichlorodiphenyltrichloroethane stand for a type of virus?
No, it is a chemical formula for the insecticide known as DDT.
A virus is a twist of RNA or DNA inside a protein sheath, it doesn't have a chemical formula as such, not one that could be easily written.
How often can you get the flu in one year?
It's possible to get the flu quite a few times, although once or twice is more common -- counting inoculation/vaccination as one time. :}
There are three major strains of influenza, cleverly named A, B and C. Each can infect humans and, in temperate climates, tend to cluster in a 1-2 month period in the winter. Usually, one strain is prevalent, although the other two strains may appear in lower concentrations in a given year. The problem is that, when two parent viruses of the same type (particularly type A) share DNA and produce a progeny or child virus, that progeny may have characteristics that resist antibodies that are effective against the parent strain (and that year's vaccine). While prior infection or inoculation against one strain will typically generate sufficient antibodies to stave off a re-infection by the genetically identical strain, those antibodies may be useless against progeny. So it depends on the rate of mutation.
What are the main components that all viruses have?

Can rabies be trasmitted through a scab?
The only way rabies can be spread is if a animal infected bites or scratches you. If u think an animal is infected stay away an call for help.
How do you get exposed to the flu?
You get the Flu be generally being with people that are infected. You can also get them by being in a unclean atmosphere or house/bulding.
Does chickenpox have single-stranded or double-stranded DNA?
Varicella-zoster virus, the virus that causes chickenpox, has a double-stranded DNA genome.
What is the dormant state of a virus called?
The lysogenic cycle. This is when the virus incorporates its genetic material into the hosts genetic material and becomes what is called a provirus.
How can christian science get you out of the flu shot?
It is your constitutional right to not get a flu shot. It is against my religious belief as a Christian Scientist.
How is the Coronavirus COVID19 treated?
COVID-19 is an infectious disease caused by a new coronavirus discovered after an outbreak in Wuhan, China, in December 2019.
Since the initial outbreak, this coronavirus, known as SARS-CoV-2, has spread to more than 100 countries around the world, and has affected many thousands of people.
As yet, there’s no vaccine against the novel coronavirus. Researchers are currently working on creating a vaccine specifically for this virus, as well as potential treatments for COVID-19. Zinff staff recommend anyone should stay in your home.
