Установите последовательность событий, связанных с ее делением. А) удвоение хромосом Б) образование двух дочерних клеток В) расхождение хромосом к полюсам Г) оформление двух ядер Д) разрушение ядерной оболочки Е) расположение хромосом вдоль экватора клетки
Большинство водных и наземных олигохет — «мусорщики», питающиеся мертвой органикой, в первую очередь растительного происхождения. Дождевые черви питаются разлагающейся органикой поверхностного слоя почвы и могут затаскивать опавшие листья в норки. Будучи детритофагами, они поглощают органический материал вместе с заглатываемым грунтом. Мелкодисперсный детрит, водоросли и микроорганизмы — важные источники пищи для некрупных пресноводных форм. Часто встречающиеся маленькие олигохеты Aeolosoma собирают детрит с простомиума. В процессе питания червь прижимает вентральную, покрытую ресничками поверхность
