While there were many species of mites, springtails, and other tiny bugs in our bin, we were missing predators. I ordered a few million nematodes (a kind of tiny roundworm) by mail. Within a few weeks (long enough for the adult flies to die off and their larva to have been eaten) we had a fly-free bin.
All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Single-celled organisms use cell division as their method of reproduction. Somatic cells divide regularly; all human cells (except for the cells that produce eggs and sperm) are somatic cells.
Cell Growth and Division. Why do cells divide? - large cells have difficulty transporting enough nutrients across their membran . Cells are limited in size by their SURFACE AREA and VOLUME ratio . CELL DIVISION - Process where a cell splits into two identical daughter cells. It occurs it two main phases.-Mitosis - division of the nucleus
