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.
Introduction. 1  Mitosis is used for almost all of your bodyâs cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. 2  Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametesâsex cells, or sperm and eggs.
