Imagine you come across a small worm. How can you determine whether it is a class Hirudinida or a turbellarian? Give two distinct differences between the two without naming the same structure/invisible features of each animal (e.g animal x has 2 wings, animal y has 4 wings are not distinct differences)

Make a phylogenetic tree about: Amphioxus; Lamprey; an osteostracan( derived ostracoderm); Reef shark;African lungfish and   cichlid ( teleost fish) and label the cladogram with the following clades and characters Clade:Chordata; Vertebrata; Gnathostomata; Chondrichthyes 5.    Osteichthyes (bony fishes); Sarcopterygii (lobe-finned fishes) and     Actinopterygii (ray-finned fishes)  Characters: Notochord; Muscular pharynx; Dermal bone; Pectoral fins •    Jaw; Pelvic fins; Endochondral bone; Lobed fins and 7 clusters of Hox genes Amphioxus; Lamprey; an osteostracan( derived ostracoderm); Reef shark;African lungfish and   cichlid ( teleost fish) and label the cladogram with the following clades and characters Clade:Chordata; Vertebrata; Gnathostomata; Chondrichthyes 5.    Osteichthyes (bony fishes); Sarcopterygii (lobe-finned fishes) and     Actinopterygii (ray-finned fishes)  Characters: Notochord; Muscular pharynx; Dermal bone; Pectoral fins •    Jaw; Pelvic fins; Endochondral bone;…

Snails, like the Euhadra land snails, are part of the phylum of Mollusks, in the group gastropods. A general phylogeny of mollusks is shown below, as well as a details phylogeny of some land snails.

Charles a Biology student in California has found at the beach an animal he cannot name. What are some of the questions that he should ask to help determine the phylum of the animal?

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.

Including the whole tree, how many monophyletic groups could you make from the tree below?

Why are “reptiles,” as traditionally defined, a paraphyletic group? How has cladistic taxonomy revised Reptilia to make it monophyletic?
