- What does radial symmetry means? What is the type of symmetry found in chordates? Which are other phyla of the animal kingdom that present species with radial symmetry?arrow_forwardA) 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.arrow_forwardWhich of the following is a synapomorphy for mammals? a)Lactation b)Limbs c)Circulatory system d)Amniotic eggarrow_forward

- Which of the following is the correct classification for this chordate animal: This vertebrate possesses hair and mammary glands. They are endothermic. This group gives birth to live young at a fetal stage. Most then nurture their young in a pouch.

- On a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton. What other traits is it likely to have based on this type of development Radial symmetry Coelem Central Nervous System Two germ layers present yes or no for eacharrow_forwardWhat are the reasons that you can think of for the arthropods to constitute the largest group of the animal kingdom?arrow_forwardWhat would have happened to major vertebrate groups if urinary and reproductive went on to evolved independently all throughout history?arrow_forward
