Abiogenic matter of extraterrestrial origin

Among the substance of extraterrestrial origin nor alive, nor nutrients are not scientifically established. So, despite vigorous searches, no trace of the living and the nutrient of extraterrestrial origin has not yet been found. As for the abiogenic matter of extraterrestrial origin, then this is the real thing. About meteorites known, of course, but it's pretty rare natural phenomenon. From the XV century to the present day on Earth at the time of incidence was observed and was chosen only a few hundred meteorites. Meteorites are the most well-known, but not the most common form of abiogenic matter of extraterrestrial origin. In its structure dominated by meteoric dust particles with a diameter of tens of microns and even smaller particles with sizes approaching molecular. These particles are most easily detected in the sediments differ greatly from them in composition: in the deep ocean sediments and glaciers. It is for these objects and is usually carried out a study of extraterrestrial matter. Its total amount that falls annually from space in Earth's biosphere, according to various estimates vary widely. This, of course, a little bit, but for 4.5 billion years of Earth on it has accumulated a layer of material of extraterrestrial origin capacity of several hundred meters - anywhere, however, is not presented in its purest form. In essence, the earth's crust - is a complex composition of matter terrestrial and extraterrestrial origin.
Living matter in its mass is even more insignificant part of the biosphere.
Consider what the specific properties of living matter.
1. Living matter of the biosphere is characterized by a huge free energy. In the inorganic world in terms of free energy from living matter can be compared not only solidified lava flows.
2. Sharp distinction between the animate and inanimate matter is observed in the rate of chemical reactions: reactions in living matter are thousands of times faster.
To preserve the external skeleton is sometimes necessary to "shift". So, molluscs living in acidic waters, in which the substance of their calcareous shells can be easily dissolved, cover it outside of chitin.
Rate of reproduction of organisms, usually inversely proportional to their size.
