Consider the following information. chimpanzees have a tibia (shin bone), whose upper end is "t" shaped, as it does not have to support their entire body weight. the "t" shaped tibia is an ancestral characteristic shared by most primates. humans and members of the genus australopithecus, a fossil primate, have a "y" shape to the upper tibia, capable of supporting the full body weight, and evidence of bidpedalism. the "y" shaped tibia is a recent evolutionary adaptation, or a derived trait. additionally, australopithecus shares an ancestral small cranium with chimps and gorillas, while humans have a derived large cranium. you design a phylogenetic tree based on the information describe above. what type of approach have you employed in your classification scheme?
a) traditional approach.
b) cladistic approach.

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
