Viruses (biological)

White blood cells, specifically T cells and B cells, play a key role in helping the body fight off a cold by recognizing and attacking the virus. They work together to create antibodies that target the virus and help the immune system remember how to fight off the same virus in the future.

A virus is protected from damage by its protein coat, which helps shield its genetic material. Additionally, viruses can enter host cells to hijack their machinery for replication and evade the immune response. Some viruses also have mechanisms to repair any damage that may occur during replication.

Yes, chickenpox is a viral disease and all viruses need host cells to reproduce and cause an organism health problems.

Generally, the protein coat that surrounds the viral genetic material and any reverse trascriptase enzymes. This capsid stays outside the cell attacked while the genetic material and whatever else is needed is injected into the cell or the capsid merges with the cell membrane and the vital viral material enters the cell.

It is not believed so, but viruses are able to infect cells and replace the cell's DNA "instructions" with the virus' DNA or RNA instructions. This is how they reproduce using a host's cells to do the work. There is some thought in the scientific research areas that one day we may be able to do gene therapy using viruses to implant the correction into the target cell types, but not yet.

Viruses themselves can mutate into new forms, however, and this may be what you are thinking of. The viruses are able to change the proteins in their capsid (coat) and make new viruses through this mutation that no longer get attacked by our immune systems. Our bodies no longer recognize them as the same with the different protein composition and our immune defenses that were developed against the original version of the virus won't work any more until our bodies develop new antibodies for the mutated strain of virus.

If you are asking if a virus can live very long without its host, then no. Viruses aren't alive in the first place. Because viruses can't reproduce on their own, they are not considered living organisms. Because they aren't living to begin with, they cannot die.

The cell structure lend itself to the function of the cell because it has to support the fuction of the cells. Just like how a bigger boy needs to eat more to get bigger. Many times the number and types of organelles allow cells to differ dramatically in terms of their specialized functions. For example the reason why your heart beats constantly is because the cells in the heart contain many mitochondria to upkeep the required energy for the heart to keep beating

A latent virus remains dormant in the host cell without actively reproducing. When triggered by certain factors, such as stress or a weakened immune system, the virus can reactivate and begin replicating in the host cell to produce new viral particles.

No, Ameba Pico is not a virus. It is a legitimate online game that can be played on social platforms like Facebook. However, it is important to ensure that you access the game through official and secure channels to avoid any potential risks.

Yes, virus is a germ because it has very harmful effects on living things and it cause several types of diseases such as rubella etc.We can take anti-viral to avoid virus but it can take long time.

A single cell virus particle is called a virion. It consists of genetic material enclosed in a protein coat.

They are obligate in the sense that they cannot replicate outside of a host cell.

To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.

Adenovirus have an icosahedral capsid with a glycoprotein spike at each vertex and has DNA as their genome.

RNA is not an virus, but a macromolecule (nucleic acid)

Cells respond to bacteria or viruses by initiating an immune response. This typically involves detecting the foreign pathogen, activating immune cells to destroy the invader, and producing antibodies to neutralize the threat. Inflammatory molecules are released to recruit more immune cells to the site of infection for an effective defense.

None. Swine flu is an illness caused by the pathogen known now as swine flu virus, A-H1N1/09 influenza. The illness contains no immune cells, nor does the virus. Your body responds to the presence of the virus with an immune response that sends your own immune cells to the area of your body where the flu virus has invaded. It is your body's immune cells that enter the "fight" and eventually get rid of the virus by constructing the type of immune cells called antibodies that are a perfect fit to inactivate the specific virus so it can no longer cause cell damage and symptoms of the flu. Your body then remembers the antibodies that worked to inactivate the virus so it can use them in the future if you are ever exposed to that virus again.

Well, it is possible it could evolve from Rabies or other agression diseases. It is very possible they could mutate it from the diseases or make it as an biological weapon.

they can not reproduce without a host cell .

No, not all viruses are deadly. Some viruses cause mild illnesses like the common cold, while others can be severe and potentially life-threatening. The severity of a virus depends on various factors such as the individual's immune system and how easily the virus spreads.

Viruses enter animal cells by attaching to specific receptor molecules on the cell surface, which allows for the virus to enter the cell through either membrane fusion or endocytosis. Once inside the cell, the virus uses the cellular machinery to replicate and spread.

Because it doesn't use it's DNA or RNA to function, it uses it to inject into a cell and switch the cell's instructions to its own so the cell will make more viruses. Cells have DNA and RNA to tell the cell what to do, but viruses just do it naturally. Viruses have no use for both.

A bacterial cell is a single-celled organism, but a virus is just a protein wall containing DNA or RNA, which it injects into the nucleus of a cell to cause it to start replicating the virus's NA rather than the cell's own. Bacteria are large enough to be seen with optical microscopes, but virus's are so small they weren't discovered until electron microscopes came along. Bacteria are alive and virus's are not. Bacteria can be killed and therefor cured. Virus's live in the blood and they can be treated but not cured and it could always show itself again. bacteria are cellular form of life, bacteria can be good or bad. Good bacteria in intestines which help digestion, bad bacteria such as pathogens are able to reproduce on their own. Virus's are pathogenic, virus's are not cells, and they reproduce by taking over cells.

The polymorphic virus in 1991 was called the Tequila virus. It was one of the first viruses to utilize polymorphic code to change its appearance with each infection, making it harder to detect and remove.

Some viral diseases are curable and some are not. This will change with time as we learn ore about specific viral diseases.

There are also many viruses that do not cause human disease and for them there is no need to determine whether a "cure" can be found.

Viruses can be beneficial to humans by serving as tools for gene therapy and gene editing, aiding in the development of vaccines, and contributing to the regulation of the immune system. They can also contribute to the diversity of the human microbiome.
