PRELIMINARY EXAMINATION I NAME: ___________________ ID No.: ___________________ PRELIMINARY EXAMINATION 1 - 2005 GENERAL PARASITOLOGY DATE: MARCH 15, 2005 PLEASE WRITE YOUR NAME ON EVERY PAGE. ALSO, RECORD YOUR ID NUMBER IF YOU KNOW WHAT IT IS. Examinations : Each examination will consist of 50 multiple-choice questions, with only a single correct answer per question. Keys will be posted as soon as it is verified that all students have taken the exam. I will change how a question is graded if it becomes obvious from class performance that it was written incorrectly or in an ambiguous manner. Answers are recorded on bubble sheets and graded by machine; I will also ask that answers be recorded on the test paper itself. It is probably going to take me a week to get this back to you, mainly because I will be out of town. I will get it aback as fast as I can. Grades: Each question on each examination will be worth 2 points; thus, there will be a total of 300 points in the course. Your final numeric total divided by 3 will determine your grade. Rounding is performed by the simple method that any fraction over a whole number will be rounded to the next whole number, i.e., 91.009, 91.1, and 91.7 will all equal 92. Grades will be based on the Cornell formula: <60 F, 60-62 D-, 63-65 D, 66-69 D+, 70-72 C-, 73-75 C, 76-79 C+, 80-82 B-, 83-85 B, 86-89 B+, 90-92 A-, 93- 95 A, 96-100 A+

Figure 1.1 in the text shows "An attempt to find 'parasitism's place' within the context of symbiotic relationships." In this figure one circle is said to be due to an indirect trophic relationship" where according to the text "The benefit gained is unidirectional, one partner benefits and the other in neither harmed nor helped.

In the text, Box 3.1, Microsporidia (Microspora) are said to be primitive eukaryotes that may belong in their own Kingdom because they lack centrioles, mitochondria, and have a 70S prokaryote-like ribosome. The DNA of two Microsporidia have been completely sequenced, and they appear to now fall well within the range of a.
