Biology 1510 Spring 2007: Exam 1 (version 1) General Instructions: • Read these instructions. Do not open this exam until instructed to do so. • Note the version of this exam, which is shown in the header to each page. Bubble in the version number in Column P under "Special Codes". If you do this incorrectly, your exam will not be graded with the correct key, which will likely result in a very poor grade. • Completely fill in your name and 9-digit GT ID number (9xxxxxxxx) on the left side of the exam sheet. Start entering your ID number from the first column on the left and leave the last column blank. Your ID number is critical in entering your score into the class database. Any errors in your name and/or ID entries will result in 5 points being subtracted from your final score! This is not a joke! • Write your lab section ID in the top right corner of your scantron sheet. • This exam contains 52 questions, each worth 2 points. You can score a maximum of 100 points on this exam, so you can potentially attain the maximum score even if you skip or miss 2 questions. • Please look over the entire exam before starting to work on any part of it. Please make sure that your copy of the exam includes all 11 pages of questions. • Write your name at the bottom of each exam page. • Please think through each answer carefully. None of these are intended to be trick questions, so try to answer only the question asked. Choose the best answer among the choices given. • Turn in both the question sheets and the answer sheet. You must show your student ID and tell us your lab section (day & time) when you turn in your exam. Please be prepared when you come up to the front of the class. • Good luck!
