Viruses belong to living things, do they starve to death?

When the energy in the cell is not enough to maintain life activities, the virus will stop life activities, like hibernation, and will reproduce and resurrect under suitable conditions, so the first question: no.

The main components of the virus are DNA and protein, and high temperature can permanently inactivate and denature the protein, destroying the physiological structure of the virus, so burning it with fire can kill him.

Viruses and bacteria are two different concepts, bacteria have a cellular structure, while viruses do not, so viruses are generally excluded from cellular organisms, and the structure of viruses is a protein shell that encapsulates DNA molecules, and there is no cellular structure, which is a "single-celled organism" in appearance

The biological ** has been left for a long time, and the virus inside exists in the form of crystals and is still infectious.

High temperatures can kill almost all viruses, and although there are viruses that resist high temperatures, 120 degrees Celsius is also the limit.

The method of killing the virus: destroying its structure, such as denaturing its protein (84, high concentration of alcohol, etc.) destroying its DNA (ultraviolet irradiation) This is a universal method.

Some drugs are specific to the virus (only effective against one or a few viruses).

Some viruses are only contagious to a species.

Viruses are inherently smaller than bacteria.

If you stay away from him, you won't be infected.

High temperature can kill viruses, it has no cell structure, it is indeed smaller than bacteria, they survive in bacteria or cells, constantly replicating themselves, each virus has its own characteristics, there are many ways to kill them, of course no living thing can survive under extreme conditions, extremely high temperature will deteriorate proteins and nucleic acids, it is a special organism. All viruses infect other cells because it is in the cells that they show biological activity.

Viruses are a class of microorganisms that do not have a cellular structure and have life characteristics such as genetics and replication.

Virus, like all living things, has the ability of heredity, mutation, evolution, is a very small size, extremely simple structure of life form, virus has a high degree of parasitism, completely dependent on the host cell's energy and metabolic system, access to the material and energy required for life activities, leaving the host cell, it is just a large chemical molecule, stop activity, can be made into protein crystallization, for a non-living body, encounter the host cell it will be adsorbed, enter, replicate, assemble, The virus is a primitive life form between living and non-living organisms because it releases progeny viruses and shows typical characteristics of living organisms.

The body is extremely small and can generally pass through the bacterial filter, so the virus is called a "filtered virus" and must be observed under an electron microscope.

There is no cell structure, and its main components are only nucleic acids and proteins, so it is also called "molecular biology";

In vitro conditions, it can exist in the state of inanimate biological macromolecules and maintain its infection vitality for a long time, which is one of the reasons why the virus does not die of starvation.

There are many ways to kill viruses, but not all of them can kill all viruses.

If they continue to grow in an environment where they can reproduce, it will be very difficult.

Just like the sleep mode of a computer, the virus needs the living organism to provide it with the energy needed for life activities to survive, when it leaves the organism, the crystals will be preserved, the virus will enter a dormant state, and when it enters the organism again, the virus will resume normal life activities from the dormant state. The so-called "death" of a virus actually means that the protein of the virus is inactive, or the DNA in the crystal is destroyed (such as a computer system program is destroyed and collapsed, or the host computer is smashed), and the virus cannot resume its life activities. A virus in the air is a virus that leaves an organism and is therefore a crystalline.

In the crystalline state, the virus has no life activity, but it is more resistant to harsh environments than in living organisms. However, due to environmental factors, the crystals will still be damaged by high and low temperatures, as well as chemical drugs, so viruses in the air will die if the environment is not suitable. In contrast, viruses in organisms are more likely to survive because they are protected by the parasitic organism's defense system – provided that the organism's immune system does not kill the virus.

"No signs of life" is not entirely true, the virus can still survive when it encounters an organism, but because it is dormant, it cannot move, cannot actively find a host, and must rely on the natural environment (air flow, water flow, biological chain, etc.) to move.

Therefore, "the virus dies when it leaves the living organism" is incorrect, the crystals are dormant viruses and are alive; Airborne viruses are dormant crystals; The reason why a virus cannot live independently is that it cannot obtain energy on its own and must rely on living organisms for it.

The poison will die when it leaves the living organism, this sentence is wrong, the crystal is alive, the virus cannot live independently, the virus in the air is the crystal.

No, it can be said that it is alive or it is not alive, because it is a dormant body of the virus, and it will grow again in a suitable environment, and the virus in the air is a polymorphosome body.

Well, he had to be attached to a living organism to live.

On February 19, 2020, the tomato virus was reported in France. It is currently rampant mainly in the French department of Finistère, and the virus suddenly appeared again this year when the new crown pneumonia was severe. It's scary for a while.

Thankfully, the virus does not spread from person to person.

Yes! Because it can multiply, it can be genetically mutated (in fact, the definition of a virus as a living organism is still controversial, but these two should indicate that the virus has life characteristics).

A virus is a type of microorganism and cannot be said to be a complete living organism because it must parasitize in living cells, rely on living cells for energy, and replicate itself. For details, you can check the encyclopedia.

A virus is a non-cellular parasitic organism composed of nucleic acid molecules and proteins.

In terms of the (physiological) definition, viruses can only carry out metabolic activities within the host cell, so it can be unambiguously said that viruses are living within the host cell; Without cells, there is no life!

A virus is a microorganism and is a special organism that does not have a cellular structure.

The most fundamental difference between living things and non-living things is that living organisms can be metabolized, and viruses can be metabolized after invading the host cell, so they belong to living organisms.

Attached: Six basic characteristics of living things Common material and structural basis, metabolism, stress, growth, development and reproductive phenomena, genetic and mutation characteristics, adaptation and influence of the environment. These basic characteristics are only possessed by living beings, and cannot be possessed by non-living things.

Viruses can exhibit life phenomena when they have host cells, but without the host, because they cannot synthesize the nutrients they need, cannot carry out normal life activities, and cannot carry out normal cell metabolism, they cannot exhibit life phenomena, so it can only be said that viruses are a wonderful organism between life and non-life.

Viruses are a wonderful creature somewhere between life and inanimateness. If you explain in detail, the number of words you can ask is too small.

Viruses are considered biological in China, but not biological in those places in the United States, so there is no standard definition

Yes, viruses can be metabolized, which is in line with the characteristics of life.

Surely death.

It's dead, but the DNA is still there, and its DNA is introduced into living cells, and it's still virulent, infectious.

Without host cells, viruses are biologically inactive.

A virus is, of course, a living organism.

For most animals, reproduction is an instinct, and there is no will.

It certainly doesn't know that its presence will destroy and destroy its host, and for it, it's just doing what it's supposed to do. But no living thing, including humans, would not eat for fear of running out of food.

Viruses can survive and multiply, so they are considered a living organism. Viruses don't have a nervous system, so it can't have a will. Virus mutation is not a conscious behavior, most of this mutation is harmful to the virus, most of the mutated viruses cannot survive, but the virus has a strong ability to reproduce, so it ensures normal reproduction.

The mutation of the virus does not increase the ability to adapt to the environment, but it only makes the host's immune system unrecognized. Whether an organism can continue to reproduce depends on the results of natural selection. If a virus kills all the organisms that can be parasitized, the virus will naturally disappear, and if it doesn't, it can continue to multiply.

Moreover, most viruses do not cause host death.

It's just that now there is a small percentage of scientists who believe that viruses are not living things. But in textbooks and in everyday life, people think that viruses are living things. Viruses have no nervous system, so it has no will.

P.S. A virus is a non-cellular parasitic organism composed of a nucleic acid molecule (DNA or RNA) and a protein.

A biological virus is a non-cellular microorganism that is small, simple in structure, contains only a single nucleic acid (DNA RNA), and must parasitize in living cells and proliferate in a replication manner.

Virus, like all living things, has the ability of heredity, mutation, evolution, is a very small size, extremely simple structure of life form, virus has a high degree of parasitism, completely dependent on the host cell's energy and metabolic system, access to the material and energy required for life activities, leaving the host cell, it is just a large chemical molecule, stop activity, can be made into protein crystallization, for a non-living body, encounter the host cell it will be adsorbed, enter, replicate, assemble, The virus is a primitive life form between living and non-living organisms because it releases progeny viruses and shows typical characteristics of living organisms.

Viruses are living things because they have the three main characteristics of life: metabolism, excitability, and reproduction. But it has no will, the genes of organisms are obtained by inheritance, which is where the stability of genes lies, but at the same time of heredity, changes occur, this change is called mutation, and the mutated genes will also be inherited, which is the basis of the evolution of species.

Some mutations will bring changes to the species that are more adapted to survival, while most mutations will bring destruction, which is Darwin's purification theory. The reason why viruses can constantly change their genes to adapt to the environment and survive is because of its huge reproduction volume, although the variation of adaptation to the environment accounts for only a small part of the total, but because the base is too large, this part is also very considerable. As for the harm to the host that no living thing can avoid in the process of survival, it is understandable to think of the destruction of the environment by humans.

This is not a paradox but the automatic regulation of the biosphere, when a certain organism is too much, it will cause damage to its living environment, the unfavorable living environment will cause the population to decline, and the reduced population will also reduce the environmental damage to the environment, the environment will gradually recover, the population will increase again, and it will always be maintained at a balanced level. Nature is wonderful!

All the wills and instincts of a computer virus are given to it by man, it should not be regarded as a living thing, it is just a program designed by man, everything it does is to accept the instructions of man, the purpose of its survival is to destroy the host, if it cannot destroy the host, it cannot be called a virus, then it is a "paradox" to ask this question itself.

It can't be regarded as a living being, it is a program created by humans, but it has the ability to spread on its own, and I think it is a kind of artificial intelligence. It has only a single function, or is it designed by humans, so it has no will. It's just a program, that's my opinion.

A virus should be considered a living organism because it is also alive, but it has no will, because only human beings have it.

It should not be a living being, it should be a kind of existence that sets a fixed pattern, systematically destroys, and has no subjective will, similar to AI, but it is not created by humans, it is nature. Viruses also have an inevitability.

Viruses are living organisms because they have the ability to reproduce and contain the genetic material RNA

A "virus" in a computer is a program, and a "virus" in an organism is a living organism.

Upstairs, the landlord asked about viruses in nature, not computer viruses!

Computer viruses are not everything else.

Viruses are invisible to human beings, but they are also alive, and the reason why they are called living organisms is that they are living objects, and they can also be called microorganisms.
