Investigation. Explain how an earthworm demonstrates cephalization. Although they are related, the digestive system of an earth worm and Ascaris are very different. Cephalization is the clustering of sensory organs at the anterior; a body plan that arose because animals use forward motion, and so this end is the first to encounter the environmental stimuli to which an organism must react. 4. compare the reproductive system of the earthworm with that of ascaris. 5. Assuming that seawater contains only NaCl, estimate its molal concentration. is distributed through the segmented body, along a nerve core, which lends support to the claim that earthworms have no cephalization 3.

Some may argue that the worm does not represent this, however, the ganglion in their nervous system does act as a brain. Living things respond.Living things reproduce.Living things evolve. In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. Ignore interest charges. An earth worm demonstrate cephalization through an an enlarged ganglion that acts as a simple brain. explain how an earthworm demonstrates cephalization-earthworm's digestive systems are able to break down soil to get nutrients-parasitic worms get their nutrients from living host organisms. Hence, the earthworm exhibits cephalization. Although they are related, the digestive system of an earth worm and Ascaris are very different. What are some ways that annelids are beneficial? Cephalization is an evolutionary trend in which, over many generations, the mouth, sense organs, and nerve ganglia become concentrated at the front end of an animal, producing a head region. 4. compare the reproductive system of the earthworm with that of ascaris.
