The structure of viruses is so simple, why can they still be the most stubborn creatures on the plan

It is precisely because of the simple structure of the virus that the virus can survive in many places, and it can survive under extremely harsh living conditions, so it can stubbornly survive.

Because although the structure of viruses is very simple, there are many viruses, and there are viruses in many places, and viruses must exist.

Because they are very reproductive, have a long incubation period, and may be dormant for several years, and they are very mutating and quite survivable.

First of all, because the virus is too small, we can't deal with it in a conventional way, and the virus is tenacious, because they only have genes and proteins, so there are not many points that can be attacked.

First of all, because it's too small, we can't deal with it in the usual way. Not to mention the naked eye, even an optical microscope cannot see the true face of the virus, and it needs to be seen with an electron microscope. Second, viruses are tenacious, and because they only have genes and proteins, there are not many points that can be attacked.

The genes of viruses are relatively simple and easy to mutate. Genetic mutations in complex organisms can lead to death, but viruses are not, and as long as they are not too exaggerated, they are difficult to kill the virus.

Because in a complex environment, single-celled organisms continue to evolve, discover each other's strengths, and combine with each other to form multicellular organisms. In the early days of multicellular organisms, the body was also very simple. About hundreds of millions of years ago, they gradually evolved into organs such as the heart, which became more and more complex and could perform more and more difficult behaviors.

To this day, such a world of flowers and flowers is full of life.

Because although it has a simple structure, it is very transmissible, which makes it difficult for all medical scientists in the world to control it.

3. Viruses may come from the bodies of ancient lifeforms, but they are not lifeforms in nature. In fact, I have to say that it is a virus, which may originate from a part of the life forms in ancient times, and then break away from the shackles of life itself, but it is worth noting that the virus itself has no thoughts, and it does not belong to intelligent life forms, so the virus cannot be the real ruler of the earth and can only rely on other forms of life to reproduce itself.

In fact, I have to say that viruses are indeed special, but compared to living organisms, there are still many differences between viruses and real living organisms, and it is precisely because of this that it is difficult for viruses to be the real rulers of the earth.

Personally, I feel that viruses are really the real rulers of the planet, because nothing is currently capable of eradicating these viruses, and they have survived for too long.

According to the research of experts and scientists, viruses are organisms without intelligence, they are composed of microorganisms with a simple structure, but they are difficult to solve!

I don't think so, because for thousands of years, human beings are still the head of everything, and viruses can be dealt with with some drugs.

Summary. Hello! With the exception of viruses, all living things are made up of cells, and viruses are the simplest organisms ever discovered.

With the exception of viruses, living organisms are made up of the simplest structures found so far.

Hello! With the exception of viruses, all living things are made up of cells, and viruses are the simplest organisms ever discovered.

With the exception of viruses, living organisms are made up of cells.

Formula: (one, one, one) metabolism; (one, one, one); (1, 1, 1) The one who draws the horizontal line is to be filled.

Metabolism; growth and development; heredity and variation; Reproduction; irritability; Except for viruses, other organisms are made up of cells Viruses are a special class of organisms that do not have a cell structure, and the entire body is composed only of the outer shell of proteins and the genetic material inside, so it is the simplest organism

Viruses are a kind of microorganisms with a very simple structure, which has no cell structure, mainly composed of protein shells and internal genetic material Virus individuals are extremely small and can only be seen with the help of electron microscopes; The nutritional mode of the virus is parasitism, and it must be parasitic in the living cells of other organisms in order to live; Viruses reproduce their offspring by replicating themselves

So viruses have no cellular structure and are only made up of protein shells and genetic material inside <>

So the answer is: cells.

It's because you say that a virus has no life, and it can be transmitted and can be regenerated, and you say it has life, but it really doesn't have any life characteristics, and it's not even a cell.

Because viruses do not have the characteristics of life, but they can replicate and mutate on their own, scientists say so.

Because the virus will parasitize in the human body, and then spread and spread; But when people die, so does the virus.

There is no uniform definition of cell, and the more common term is that cell is the basic structural and functional unit of living organisms. It is known that all organisms except viruses are composed of cells, but the life activities of viruses must also be reflected in cells.

Generally speaking, most microorganisms such as bacteria and protozoa are composed of a single cell, that is, single-celled organisms, while higher plants and higher animals are multicellular organisms. Cells can be divided into two categories: prokaryotic cells and eukaryotic cells, but some people have proposed that they should be divided into three categories, that is, the ancient karyotic cells that originally belonged to prokaryotic cells should be separated as a parallel category. The discipline that studies cells is called cell biology.

Cells are so small that they can only be seen under a microscope and come in a variety of shapes. It is mainly composed of the nucleus and cytoplasm, and has a cell membrane on the surface. Higher plants have a cell wall outside the cell membrane, plastids in the cytoplasm, chloroplasts and vacuoles in the body, and mitochondria.

Animal cells do not have a cell wall, and centrosomes are often present in the cytoplasm, while higher plant cells do not. Cells have functions such as locomotion, nutrition, and reproduction.

Cells were discovered in 1665 by the English scientist Robert Hooke (1635-1703). At that time, he used a homemade light microscope to observe the thin slices of the cork, and when he zoomed in, he found a small space of one block at a time, which was named after the English cell, and the meaning of this English word itself has the usage of a small room one grid at a time, so it is not a new word. And the cells thus observed have long since died, and only the remnants of the plant cell wall can be seen, although he does not really see a unit of life (because there are no signs of life), <

Later generations of scientists still believe that he is indispensable, and generally speaking, he is still regarded as the first person to discover cells. In fact, it was the Dutch biologist Leeuwenhoek who was the first to discover living cells.

The main reason why viruses with simple structures have such lethality is that once they are parasitic in the host cell, they will continue to replicate. Therefore, its replication speed is extremely fast, and it can quickly occupy all the cells, so it has such lethality.

Although the structure of the virus is very simple, the virus is a kind of microorganism that must parasitize the host, although its structure is simple, but the mutation may be very large, so it has become the most lethal organism.

When the virus enters the human body, it will multiply indefinitely, swallowing up the original healthy cells in the human body, so that we humans will get sick.

A virus is a non-cellular organism with a simple structure and a tiny individual. Viruses are only composed of proteins and nucleic acids, and have neither enzymes nor protein synthesis systems, so why is such a simple and tiny virus called one of the most lethal organisms?

Viruses are parasitic organisms that can only survive and reproduce if they are parasitic in the host, and its way of reproduction is extremely peculiar. It first integrates its genetic material into the DNA of the host cell through reverse transcription, and then synthesizes the protein it needs through transcription and translation, and its genetic material is also replicated through the host cell, and finally assembles the protein and genetic material to complete its own proliferation. In other words, the proliferation of the virus is proliferated with the replication of the nucleic acid of the host cell.

In this way, the host is eroded little by little. The end result is that either the virus is killed or the virus kills the host. Judging from the current level of medicine, the latter is the majority.

Every organism that reproduces to the extreme will have special viruses to control their rate of reproduction. Rabies is an example of how canines have dominated the planet. The plague illustrates an outbreak of rodents at an alarming rate of reproduction.

And the first ** of the virus may be alien creatures, such as comets and meteors, which bring some kind of protein. (It is not unreasonable for the ancients to call comets disaster stars), at this time there was no virus formed, and what really formed a virus was some kind of medium animal, which was also the source of the virus. It is a bat, and the living environment of bats and their own virus transformation have natural advantages.

Viruses with simple structures are highly contagious and multiply, adaptable and persistent, and the antiviral drugs studied are resistant to drugs in the later stage, although they have a certain lethality temporarily.

Because it's simple, there's no target for drug binding! Some viruses have reverse transcriptase, which can be blocked with the corresponding drug! If you want to block the transcription of the virus in favor of the human body, it will be very toxic!

Nature is always a thing, the laws of nature will always exist, but a certain thing in a certain place is temporarily superior, and the bacteriocins produced by our human symbiotic lactic acid bacteria are the nemesis of these viruses and harmful bacteria, but everyone does not use it!

The reason is that viruses are very small, comparing the human body to cells, the heart to the nucleus, and viruses to molecules, and the result is that molecules attack the nucleus and cause the cell to make an exception.

The virus looks simple in structure, but it is very harmful, it will be harmful to the body, it will spread rapidly, and it will multiply, it is not beneficial, so it is very harmful.

It is precisely because of the simple structure of the virus that it is particularly easy to survive and reproduce, and there will be a large number of viruses in a short period of time.

Don't underestimate the human immune system, people with good physique have a strong self-resistance when the new virus invades, and they have the ability to kill the virus by themselves, and those with weak physique need other drug intervention to resist successfully!

Because of the variability, the plasticity is very strong, just like a small seedling can grow into a towering tree in a very short time.

Due to the long-term isolation between Eurasia and the American continent, the physical fitness of the people in the two places was completely different, and the Indians were completely inresistant to smallpox, scarlet fever and other diseases in Eurasia, so the population of the Americas would disappear in just 300 years.

I think viruses are also a part of promoting biological evolution, after all, viruses can be grafted DNF to different species, maybe organisms are playing a game under the code, but unfortunately we don't even know who the boss is at the moment.

Personally, I think that because it has a single structure, it is easy to mutate, and because it is easy to mutate, the human immune system cannot figure it out.

I think it probably doesn't have DNA of its own, and it uses the host's DNA as raw materials, which increases the uncertainty, so it's highly contagious.

The simpler the virus, the more harmful it is.

The simpler the structure, the more primitive the virus.

1 The virus does not live independently. 2. Viruses parasitize in living cells, using the material of the cell to reproduce with their own genetic material. 3. It is very difficult to destroy it.

The human structure is also simple, which has brought indescribable damage to the planet! Now that the earth is angry, this is not easy to do!

Predatory growth, expansive extinction. Like a selfish person.
