① Bacteria and viruses are pathogenic microorganisms, but their characteristics are very different. Bacteria may be small enough to be visible under a light microscope, but in addition to nucleic acids, the basic unit of life, they also have a large set of supporting facilities to survive. These include cell walls that act as residential "mansions," "warehouses" for storing nutrients, and "chemical workshops" for metabolizing. Rely on these. Fine grass can take in materials from the outside world and process them into energy. The virus, however, is much smaller and much more pitiful, and there is no "storehouse" or "workshop", not even a "thatched house" as a protective shell. It's actually one molecule in size and you can see it with an electron microscope. The whole house is just a nucleic acid that represents life. If people are compared, bacteria at least have a pair of pants, a begging bowl, and a stick to beat the dog. So while bacteria must thrive in a good environment inside the body, they can survive for a long time in a bad one. A virus, on the other hand, is like a newborn baby, with nothing but its life and a Suckling mouth, and no ability to survive on its own. Viruses can only live inside human or animal cells and survive by "stealing" readily available nutrients from the cells. Once out of the body, the virus doesn't live for more than a few hours. ③ Most antibiotics work on bacteria because they can inhibit cell reproduction and interfere with their formation of new genetic structures or cell walls. And because viruses can only live in other people's cells, they can't perform these biochemical reactions on their own. So antibiotics have no effect on viruses.
