Biology Tutor

We all learned a little. In my time, biology lessons at school passed without attracting attention. An oral subject. Then life was fine without this biology and everything else that did not become part of the profession.
Lately, there is more and more biology around and there is no escape from it. Every news iron is broadcasting something about dangerous viruses, artificial meat, cloning of direwolves. Fences are full of ads for diet pills, genetic tests and even homeopathy. And in the spring, as before, flowers, beetles, birds. Well, in your personal inner world, something biological is happening all the time.
In general, if you are not a pro and school biology passed you by or has long been forgotten, but you still want to understand - let me know. Write in the comments or in a personal message. I will answer questions in detail.
