Earthworm is the common name for the largest members of Oligochaeta (which is either a class or subclass depending on the author) in the phylum Annelida. In classical systems they were placed in the order Opisthopora‚ on the basis of the male pores opening posterior to the female pores‚ even though the internal male segments are anterior to the female. Theoretical cladistic studies have placed them instead in the suborder Lumbricina of the order Haplotaxida‚ but this may again soon change. Folk names

The seven processes of life The seven processes of life are the key to all living organisms: these processes consist of nutrition‚ growth‚ movement‚ respiration‚ reproduction‚ sensitivity and excretion. Although‚ they may be achieved in different ways depending on the organism. These processes happen with in both plants and animals; in each organ‚ cell and organelle. All these processes are interlinked and have a chain effect upon one another. Without one of them the others aren’t possible.

From a medical background i can purport that figs are known to be an energizing health tonic‚ they act as a natural laxative‚ aid digestion‚ help to relieve the symptoms of pre-menstrual syndrome (PMS)‚ help to fight cancer and the juice kills roundworms and bacteria Japanese scientists have isolated an anti-cancer chemical contained in figs called ‘benzaldehyde’‚ which is used to treat advanced cancer patients. Other researchers have isolated enzymes known as ‘ficins’ in figs‚ which aids digestion

highly branched gastrovascular cavity which is the site of both digestion and circulation of nutrients. There is no separate exit‚ so undigested food has to leave by the mouth. There is no system within the body to distribute oxygen‚ this constrains flatworms to be flat‚ as they must respire by diffusion and no cell can be too far from the outside. Planaria are quite active‚ moving by contraction of muscle fibers that are oriented in different directions‚ in a manner similar to how we move our tongues

Introduction An organism that studied to better understand the biology of another organism is considered to be a model organism. There are several organisms used or model organisms used for humans‚ mice‚ frogs‚ roundworm‚ chicks‚ fish‚ and fruit flies. All of these organisms ate much smaller and easier to care for and observe. A major advantage to using these model organisms are their ability to rapidly develop off spring often times in much larger numbers than a human. Some organisms produce The

Nr. 50 July 2009 Climbing beans‚ double yields A lot of beans on a small place: This is the benefit of climbing beans. And they are easy to harvest! The Organic Farmer A large section of the Kenyan population is unable to afford high protein food with adequate proteins‚ such as meat and eggs. This is where beans play a very important part; they are a cheap source of proteins. Unfortunately‚ the production of beans in most parts of the country is declining. The problem is the lack of good seeds
