What is smaller than bacteria?

The smallest organism is a virus, which contains only one nucleic acid, i.e., either DNA or RNA, thus dividing viruses into two categories: DNA viruses and RNA viruses.

The smallest viruses are called micro-DNA viruses and micro-RNA viruses, which are spherical in shape and only 10-20 nm in diameter, smaller than some inanimate protein molecules.

Viruses can only multiply in living cells, but they can be purified into crystalline form.

So in fact they are living molecules between living and non-living matter, and they are the primitive stage of the origin of life in the process of biological evolution.

One level smaller than bacteria are proteins, smaller than proteins are molecules, atoms smaller than molecules, smaller than atoms are particles, and smaller than particles are quarks.

It should be food for bacteria, that is, something that can be eaten by bacteria.

Brain teasers? I know:

Son of bacteria.

Something smaller than bacteria is fungi, viruses, rickettsia, etcMycoplasma, chlamydia, treponema pallidum。cocci in bacteria are microns in diameter; Spirochetes are generally 5 to 50 microns long and microns wide. Viruses (very tiny organisms without cell structure that parasitize in biological cells, and viruses that parasitize in bacterial cells, also known as bacteriophages, are much smaller than bacteria.

The size of the different viruses varies between 20 450 nm.

Bacterial hazardsBacteria are both useful and harmful to the environment, humans and animals, and some bacteria become pathogens, causing tetanus.

Typhoid fever, pneumonia, cholera, and tuberculosis.

Gonorrhea, anthrax, plague.

trachoma, etc. In the history of mankind, infectious diseases caused by bacteria have claimed countless lives. In plants, which bacteria cause leaf spot, fire blight and rhodochre. Infection can be carried out through contact with airborne organisms, food, water, and infected organisms.

Something smaller than a bacterium is a virus. Viruses contain only one type of nucleic acid, either DNA or RNA, so viruses are divided into two categories: DNA viruses and RNA viruses. The smallest of these viruses are called micro-DNA viruses and micro-RNA viruses, which are spherical in shape and only 10-20 nm in diameter, smaller than some inanimate protein molecules.

Viruses can only multiply in living cells, but they can be purified into crystalline form.

Difference Between Virus and Bacteria

Many infections are caused by bacteria or viruses, so many people think they are more or less the same. In fact, they are similar except that they are microorganisms that are invisible to the naked eye. Bacteria do not depend on other organisms to survive, and most of them are single-celled organisms that live in nature.

A virus is a small piece of genetic material protected by a protein shell that cannot do anything on its own, has no energy**, and cannot simply feed on us or other living beings.

Something smaller than bacteriaBrain teasers? It is the son of bacteria. Many people think that what is smaller than bacteria is not the small cell on the body, and we can't use habitual thinking.

Digging deeper into biology, it's a witty and humorous statement that the children of bacteria are smaller than bacteria. Bacteria are generally microns in diameter, and the largest bacteria in the world is called Namibia.

The sulfur pearl has a diameter of millimeters, the largest can reach millimeters, and the volume is a million or even three million times that of ordinary bacteria.

The benefits of brain teasers.

Brain teasers first originated in ancient India.

It means that when the thinking encounters a special obstacle, it is necessary to quickly leave the habitual way of thinking and think about the problem from other aspects. Brain teasers are a form of entertainment as well as a popular play on words.

One of the obvious features of this kind of wordplay is that the questions are very ordinary, but the answers are very annoying or hilarious, and they can also bring people happiness and at the same time make everyone use their brains.

Smaller than bacteria is a virus, and if a virus is as tall as a person, then a medium-sized bacterium, may haveStatue of LibertySo high. Three million bacteria can comfortably sit side by side on the tip of a needle, but the smallest virus is 1,500 of bacteria, which can only be magnified by a factor of 100,000Electron microscopyMake observations.

Viruses cannot spread on their own, they float in the air, float in liquids, and even lurk in food, looking for opportunities. It reproduces millions of offspring, hoping that at least one of them will find and invade a new host.

How the virus survivesViruses mainly live in the host cells of living organisms, and they reproduce and reproduce in a self-replicating manner. The common characteristic of viruses is the ability to metamorphize, degenerate, and reproduce, but viruses must use host cells to metamorphize, degenerate, and reproduce, which is the main difference between viruses and bacteria.

A virus is a small, simple non-cellular organism that has no cellular structure.

It can infect almost all organisms with cellular structures, viral infections.

Later it is often contagious.

Among the microorganisms that have the smallest cellular structure, it is bacteria. Viruses that have less vital activity than bacteria are viruses. It is a non-cellular life form that consists of a nucleic acid strand and a shell of proteins.
