Document Summary

Need to survive immune system, reproduce, transport from host to host. Simple organism, short life cycles therefore very rapid reproduction and rapid mutation and thus genetic change. More complex organism, short life cycle therefore rapid reproduction, alternation of sexual/asexual reproduction so high genetic variation. Life cycle: eggs pond (hatches) into a snail (different larvae) cercaria in vegetation ingested eggs. Life cycle: pigs meat ingested by humans eggs worms in muscles. Very good a swimming due to high pressure in the body) Moults outer cuticle in order to grow. Has exoskeleton that muscles are attached to. Mostly ectoparasites often vectors for microparasites. Has a coelom (body cavity lined with membrane) Hexapods (insects) 3 body sections, antennae, 3 pairs of legs.
