Study guide Exam #4
Arthropods, Hexapods & Myriapods, and Echinoderms
Next exam will be two parts.
Part one will be to select three short essay questions from a selected list of questions. I
will select five questions from the short essay questions below and you will have to
answer three. Full credit will only be given if answers are complete and essay from.
Part two will consist of 20 multiple choice questions.
