nourishment and directing the organism’s bodies towards safety or a food source. The cephalization of the Platyhelminthes was a branch off of the early jellyfish‚ which were radial‚ and not bilaterally symmetrical‚ which distinguished them from the flatworms. To be bilaterally symmetrical‚ an animal must have two identical sides of their body down the middle. The radial symmetry possessed by the jellyfish allows for one to draw a line anywhere through the organism and achieve symmetry. This stemmed from

Louise Pasteur‚ a Frenchman who was neither a physician nor a veterinarian moved into the spotlight to help find a vaccine for Rabies. He began the study of Rabies when two rabid dogs were brought into his laboratory. One of the dogs suffered from the dumb form of the disease: his lower jaw hung down‚ he foamed at the mouth‚ and his eyes had a rather vacant look. The other dog was furious: he snapped‚ bit any object held out to him‚ and let out frightening howls (McCoy 65). Through the studies

The human body shows its ability to heal itself when injured. However‚ the human body is not the only living thing that has a way of healing with no help. Planaria‚ which are free-living flatworms‚ are known for their quick regeneration from a fraction of the body. Scientists have been studying planaria and the effects of magnetism on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚

Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for
