According to what criteria do legendary and veteran members give merit to other members.
What criteria do they pay attention to in terms of merit sharing?
why ask this? because your recent thread did not even gain 1 ? this post?
Virus, microscopic infectious agents that can only infect living cells and thus replicate. Viruses; They can infect all kinds of living forms, from animals and plants to microorganisms, including bacteria and archaea.
Since Dmitri Ivanovsky described non-bacterial agents infecting tobacco plants in an article in 1892 and Martinus Beijerinck's discovery of tobacco mosaic virus in 1898, although more than 6,000 virus types have been described in detail, there are millions of types. Viruses are the most abundant type of biological entity found in almost every ecosystem on earth. The science that deals with viruses is called virology and is a subspecialty of microbiology.
Viruses can exist as virions and individual viral particles within the infected cell or during the infection process. A single virus particle that contains all the structures of a virus is called a virion or virion and consists of two or three parts: the viral genome, which can be just one of DNA or RNA, and large molecules that carry genetic material; a protein layer called capsid that surrounds and protects the genetic material and has other functions, a lipid envelope that surrounds the protein layer. Virus particles can be helical (helical), cubic or complex (complex) morphologies. Virions are too small to be seen with a light microscope. An average virion is one percent the size of an average bacterium.
The origin of viruses in the evolutionary history of life has not been explained. Some may have evolved from plasmids, which are bits of DNA that can move between cells, while others may have evolved from bacteria. In evolution, viruses are an important vehicle for horizontal gene transfer that increases genetic diversity. Viruses are considered alive by some because they carry genetic material, reproduce and undergo natural selection. However, viruses have been called "organisms on the edge of life" and "replicators" because they lack some key features (eg, cell structure) necessary to be considered living.
Viruses spread in many ways; In plants, viruses are usually transferred from plant to plant by aphids and insects feeding on plant sap, while in animals they are transmitted by bloodsucking insects, these disease-carrying organisms are called vectors. Influenza viruses spread through the respiratory tract. Norovirus and rotavirus are the most common causative agents of viral gastroenteritis and are transmitted through fecal-oral transmission and person-to-person contact, water and food. HIV is a serious agent transmitted through sexual contact and contact with infected blood. Cells that the virus can infect are called "host" cells, and the host type can be broad or narrow, determined by the "host specificity" of the virus.
Viral infections in animals often result in stimulation of the immune system and elimination of the virus causing the infection. Immune responses can also be induced by vaccination, conferring artificial immunity against certain viral agents. However, some viruses that cause AIDS and viral hepatitis evade the immune response and cause chronic infections. Antibiotics do not affect viruses, but some antiviral drugs have been developed that can affect viruses.
It wouldn't be bad to pass a little information in the covid period!
if does then be ready because you will be record as plagiarism and you will be banned sooner.
