Document Summary
Virginia walker(cid:495)s lab projects on the genetic mechanisms of resistance that we don(cid:495)t need to test on mammals (cid:523)flies(cid:524) plants, invertebrates and microbes (hydrate control) Resistance to chemicals: chemo causes birth defects, developed system so. Resistance to environmental stresses: freeze and freeze-thaw resistance in. Can be parasites, get nutrients from living animals (cid:523)athlete(cid:495)s foot, dactylella dreschsleri, arthrobotrys dactyloides) Phagocytosis (85 different proteins involved, cell eating) Digested food products are phagocytosed directly into the cells that line the gastrovascular cavity- further digested intracellularly. Wastes are excrete out of the mouth. One opening for entry and exit of food. Caecum: developed during the evolution of plant eating animals, beginning of large intestine. Rabbits eat their own poop so that the small intestine can have another chance at digesting food. Ruminant: mammal that chews cud regurgitated from its rumen. Digestive tract- mouth, esophagus, forestomach (rumen, reticulum, omasum), abomasums, intestines. Steven chu- use termites to convert cellulose into ethanol= green energy.
