1. Here is how to start. You have to show the derived characteristic for each phylum (red) on top of the branch. Next trait is cephalization and the next animal phylum is Platyhelmintes. Next complete digestive system phylum Nematoda. and so on. Use the traits (derived characteristics) that we covered in animal chapter to construct the rest of the tree.

I just need enlightenment at where exactly did I go wrong or lack in this cladogram. There is no issue with the blatospore, but only the Nematoda, Mollusca, Annelida, and Arthropoda. So, the problem is I don't know how to relocate Annelida since it doesn't undergo ecdysis, or I lack the knowledge to distinguish the correct pathway to arrange the four Phyla: Nematoda, Mollusca, Annelida, and Arthropoda; branching it correctly.
3 (8.B) A student collected the animal shown below on a field trip. The student used a dichotomous key and a microscope to classify the animal. Step Characteristic Identification Go to 2 la Possesses segmentation 1b Lacks segmentation 2a Has an exoskeleton with jointed appendages Has no exoskeleton, unjointed appendages (if any present), and a segmented worm- Go to 3 Phylum Arthropoda 2b Phylum Annelida like body; is possibly in a tube (if in a tube, may have tentacles) Possesses a foot, a radula, arms, and/or За a shell Phylum Mollusca Lacks all of the above and is dorsoventrally 3b Phylum Platyhelminthes flattened How should this animal be classified?

This chapter shows a phylogenetic tree for the three domains of life, which is based on DNA sequence data for rRNA and other genes. Which of the following answers concerning the phylogenetic relationships found within this tree is incorrect? View Available Hint(s)for Part A Euryarcheotes are found in the Archaea Diatoms, Tubulinids, and Euglenozoans belong to the domain Eukarya Forams, Fungi, and Chlamydias belong to the domain Eukarya. Spirochetes belong to the domain Bacteria Ciliates, Red Algae, and Plants belong to the domain Eukarya.
Differentiate analogous structures from homologous types. Identify which is which among the shark, pigeon and cat when you transition from each of the classes. For this, create a 4-column table with the following headings: (1) Structure, (2) Specimen a vs b, (3) Specimen b vs c, and (4) Specimen c vs a. For each cell, write either AS for analogous structures, or HS for homologous types. Note (not all structures encountered need to be here).

Imagine you come across an animal with a worm-like biody. Determine whether it is a polychaete or a member of class Hirudinida? 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)
Lepidoptera caterpillars differ from sawfly caterpillars by having more prolegs by having parthenogenesis in many species |by having a pair of stemmata rather than multiple stemmata on each side by being crochets on their feet in movement through looping for some family
