Explain the difference between holometabolous and hemimetabolous metamorphosis in insects, including stages of each.
A) Draw a phylogenetic tree for the major phyla of the animal kingdom. Label the appropriate branch points on the tree with the following features: Tissue, radial symmetry, bilateral symmetry, body cavity, deuterostomes, and protostomes.
B). Draw a diagram of a hydra. On the hydra, label the mouth (hypostome), tentacles, basal disk, ovary, budding polyp, gastrovascular cavity. State the function of each structure you labeled next to or under your diagram.
