Such Butterfly, Having Arisen From A Larva In

Such butterfly, having arisen from a larva in the morning by the end of the first days having finished a reproduction cycle, perishes. The death comes irrespective of environmental conditions - as though the factory of hours comes to an end. Similar death from the internal reason - not an exception. Still "more distinctly she can be observed at more difficult organism - . This fish within four-five years lives in Pacific ocean. During this period there is a maturing and increase in the size of a body, and in a liver and a body fat collects. But here the reproduction period comes nearer, and the humpback salmon begins the long way, sometimes in thousand kilometres, to a mouth of that river in which it was born. From the very beginning of this way fish as an energy source uses mainly hepatic reserves of fat. The stock of fats decreases, but concentration grows in blood of cholesterol which is synthesised from fat. And within one-two months fish "grows old". At it jaws are bent, eyes, a skin sink down.
