Is a virus a living thing why or why not

Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. How are virus created? We can become infected with a small number of virus particles — by inhaling particles expelled when another person coughs, for instance — and then become sick several days later as the viruses replicate within our bodies.

Likewise we probably all realize that viruses evolve over time. Is a rock alive? The name sometimes leads to misunderstandings, as the "live rock" itself is not actually alive, but rather is simply made from the aragonite skeletons of long dead corals, or other calcareous organisms, which in the ocean form the majority of coral reefs.

Can you kill a virus? Viruses insert their genetic material into a human cell's DNA in order to reproduce. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. However, antiviral medications and vaccines are specific for viruses. Can viruses mutate? Viruses mutate very quickly But every once in a while, one might help the organism survive — for example, by letting viruses infect not just birds, but people, too.

Even among viruses, though, there's a wide variation in mutation rates. HIV, for example, is a very fast mutator. What is the purpose of viruses? Viruses are considered by some to be a life form, because they carry genetic material, reproduce, and evolve through natural selection, although they lack key characteristics such as cell structure that are generally considered necessary to count as life. What is Virus explain?

Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. Viruses are non-living entities and as such do not inherently have their own metabolism. However, within the last decade, it has become clear that viruses dramatically modify cellular metabolism upon entry into a cell.

Viruses have likely evolved to induce metabolic pathways for multiple ends. Viruses undergo evolution and natural selection, just like cell-based life, and most of them evolve rapidly. Due to their simple structure, viruses cannot move or even reproduce without the help of an unwitting host cell. But when it finds a host, a virus can multiply and spread rapidly. Viruses are too small and simple to collect or use their own energy — they just steal it from the cells they infect.

Viruses require a host to reproduce. Viruses only target animals which includes humans. They also would have a protein coat known as a capsid. Scientists categorize viruses as neither living nor non- living. This is because viruses do not have the cellular machinery that is required to multiply, hence they hijack a living cell.

Another aspect that makes viruses lie on the border between the living and the non- living is their ability to be crystallized.
