NAME: ____________________________ Integrating Concepts in Biology II

Instructions for Instructors: This sample exam covering Chapters 19-21 of ICB can be used as a guide to building your own assessment. Depending upon your goals and coverage, you may need to rearrange images and questions. This set of questions is too long for a single exam; you will have to select a subset of questions. You can reduce the size of the data galleries or keep them the same length. The Data Galleries do not contain every figure from these three chapters, but contains at least the ones necessary to answer the questions. See the ICB approach to assessment guide in the Instructor Resource area for more information Instructions for Students: This exam is worth 15% of your course grade and will be due in class on Wednesday, __/__/____. No exceptions; late reviews will result in a 10%/day deduction. You may not consult any notes, old tests, internet, texts or any other person while working on this review. Do not discuss the test with anyone until all exams are turned in. Your signature at the bottom of this page signifies that the work is yours alone and is pledged under the Honor Code. Once you begin you will have four hours to complete the review.

There are 16 pages in this test, including this cover sheet. You may use a calculator and/or ruler. The answers to the questions must be typed into the space after each question. For each question or part to a question, limit your answers to the constraints given. I have given you sentence limits so be concise. Any part of your answer beyond those constraints will not be graded. Save your work often, renaming this file “lastname_review1.docx.” Send it to me electronically when finished with the exam. Alternatively, you may print it and handwrite your answers, and turn in the hardcopy, if you prefer. If you do this, staple all pages and print legibly; I can only grade what I can read.

There are several “Data Galleries” in the form of numbered figures and tables after the questions. Move appropriate figures from the galleries and incorporate them into your answers or cite the figure or table number in your answer. Do not assume that all figures will be used, or that you will only use a figure once. Simply placing data near your answer is not sufficient support: you must explain the significance of the data and how they support your written answer.

Please do not write or type your name on any page other than this cover page. Name (please type or print):

Read the pledge and sign if you can do so with honor:

16. (CH20) Compare the dates of existence of Paranthropus and Homo, using the horizontal widths of the colored boxes in the evolutionary tree below, with the mammalian communities in Africa at 2 and 1.5 million years ago, shown in Figure 20.21. In what type of habitat was each of these hominid species living? Incorporate one of the following two themes of the Evolution Big Idea: Organisms can be linked by lines of descent from common ancestry, and natural selection is a mechanism of evolution that accounts for adaptation, into your answer.
