Practice Lab Practical

This is an exam that was given during the 2006-2007 academic year. It is designed to give you an idea as to what the lab practical will be like. Images have been inserted to replace the actual specimens that you will see during the exam. Click on the answer you think is correct. Explanations have been provided to explain why certain answers are more correct than others.

	1. In which structure is the typhlosole located?
		a. A b. B c. C d. D e. none of these structures
	2. What is structure C?
		a. clitellum b. gizzard c. intestine d. exoskeleton e. parapodia
	A		B
	3. You looked at animal A in labs 1 and 2, and so you should know where they belong taxanomically. To what order do they belong?
		a. Odonata b. Diptera c. Coleoptera d. Hymenoptera e. Lepidoptera
	4. The thoraxes of animals A and B are specilized for flight. This specialization is a direct result of the fact that these animals:
	a. have undergone tagmosis     b. during development went through torsion     c. have protostome development     d. have a highly metameric body plan     e. are insects
		A B C
	5. These seemingly unrelated animals do have several traits in common. What is one of those traits?
	a. they all possess a ventral nerve cord     b. they all possess a mantle     c. they all possess setae     d. they are all metameric     e. they all possess a coelom
	6. Because animal B is a chordate, you know it possesses pharyngeal gill slits. These are modified in this animal into what structure?
		a. thyroid gland b. gills c. fins d. scales e. tail
	A		B
	7. You are more closely related to animal B than A is to animal B. However, just on appearance, animal A seems to be more similar to animal B than animal B is to you. What is a similarity shared by both animals A and B?
	a. both animals have complete guts     b. both animals are not cephalized     c. both animals are diploblastic     d. both animals lack mesoderm     e. both animals are suspension feeders
	8. What trait is found only in the phylum to which animal B belongs?
	a. radial symmetry     b. a ventral nerve cord     c. deuterostome development     d. a calcareous endoskeleton     e. the water vascular system
