I live in Russia. It's a very big country and there are different kinds of flora and fauna in it. The most common plant that is associated with my country is a birch tree. These trees are very beautiful as they have a number of attractive qualities, like colored bark and long branches. They can grow very high. I think that these trees grow nearly everywhere in central and southern parts of Russia. Another common plant is oak which is also associated with Russia and grows everywhere on its territory. As for common animals, they are foxes, wolves, hares, squirrels and bears. They live in the forests and sometimes in the fields. In water we can see different fish and in the noth of the country we can find some mammals like seal, walrus and whale. There are also a lot of birds both sonhgbirds(nightingale, starling,canary and many more)  and waterbirds (duck, swan, goose) that inhabit the territory of our country.
Some animals have become symbols of Russia and Russian cities anв towns-as an example we can name bear. 

Coronaviruses (lat. Coronaviridae) is a family of viruses that includes, as of January 2020, 40 species of RNA-containing viruses United in two subfamilies[2] that affect humans and animals. The name is associated with the structure of the virus, whose spiny appendages resemble the solar corona[3]. The purpose of the "crown" in coronaviruses is related to their specific mechanism of penetration through the cell membrane by imitating "fake molecules" of molecules that the transmembrane receptors of cells respond to. After the receptor captures the fake molecule from the "crown", it is pushed by the virus into the cell and the RNA of the virus enters the cell[4][5].
