The large diversity of shapes of biological molecules is possible because of carbon.
They are at the base of the food chain which makes the diversity possible.
It is scientifically possible to create a bomb known as the biological bomb, or simply the bio-bomb, that can wipe out only biological materials such as the human body, or any other animal or plant. This can only be created through extensive study of the human and animal body. If this were to be created to a massive scale, it is quite possible that it can wipe out a country, perhaps even a continent or the world.
not possible
Yes by extensive surgery.
Yes, everything is made of molecules.
Yes, it is very possible. For example a stone has a mass (extensive) and a density (intensive).
Carbon has 4 valence electrons, so it has lot of bonding options. This makes possible the huge diversity of compounds that involve the element carbon, which in turn, makes possible the organic compounds that make life possible.
Yes, it is possible.
The thing is, there are no levels of the biological communities. The biological community is a level in the Levels of Organization. So therefore, I don't think there is a possible answer!
Yes, protiens perform many functions; this diversity of function is made possible by the diversity of protein structures.
Its Possible
That happens all the time. Smaller molecules combine to form larger molecules; larger molecules break up into smaller molecules.
