The Final Exam will be two parts.


Part one: A total of three short answer questions will be asked. One of the questions will be question #1 below. Question #2 will come from Hemichordata and Invertebrate chordates (a-b) list below. And question #3 will come from any of the following Echinoderms- Evolution (e-n) list below.
The other two questions will come from a selected list of questions. One of the questions will come from Hemichordata and Invertebrate chordates (a-d) one short answer question will come from the list below (e-n) which I will give you a list of three to choose from and the final question will be the following:

Full credit will only be given if answers are complete and essay form.


#1. List the phylum’s we discussed in this course and the evolutionary relationship between them if any. Be sure to discuss the development of the organism (symbiosis), tissues, organs, systems, and particular anatomical structures that were key to their development and success.
#2 Hemichordata and Invertebrate chordates(a-b)

  1. Describe the evidence that links hemichordates and chordates to the same evolutionary lineage. What evidence of chordate likeness is present in adult tunicates? In larval tunicates?

  2. Describe the phylum chordate and its major characteristics. Include the function of unique characteristics associated to chordates. Also list all classes and give an example of each.

#3 Echinoder through Protozoa (e-l)

Echinoderms

  1. Compare and contrast the following classes: class Crinoidea, class Echinoidea and class Holothuridea. Give examples of each.

Hexapods and Myriapods

  1. Describe the characteristics of the subphylum Myriapods and Hexapods and there major reasons for success. Give examples of each.

Arthropods

  1. Describe the characteristics of the subphylum Crustacea and the specialization of appendages. Give examples.

Annelida

  1. Describe the characteristics of the Phylum Annelida and the advantages of metamerism. Give examples.

Mollusc

  1. Describe the two hypothesis that explains the development of the coelom and which would best fit the Flatworm as its predecessor. Give examples.

Pseudocoelomate Body Plan: Aschelminthes

  1. Describe the two hypotheses proposed for the Aschelminthes phylogeny and explain how phyla can become similar without having a common ancestor. Give examples.

Cnidirian

  1. Describe the general characteristics of the Phylum Cnidaria and its “alteration of generations”- and Describe the reproductive process of Cnidarians. Give examples.

Protozoa

  1. Describe the characteristics of the Kingdom Protozoa. Is it animal or plant? Why? Give examples
