Page 1 of 2 Dr. Reichler’s Bio 311D class time:_________ Print Name:____________KEY___________ _ Exam #2 February 29, 2008 Read each question carefully and don’t hesitate to ask if a question seems unclear. If possible, answer each question in the space provided, but if needed, continue on the back. If you use a drawing as part of your answer, be sure to also include a written explanation. These questions have specific answers, although for some, more than one answer is possible. To receive full credit you must clearly and fully answer the question being asked. The points for each question are noted in parentheses totaling 103 points. 1. If there is a dramatic shift in environmental conditions over a few years, which species would be most likely to not go extinct, one that reproduces three times per year, or one that reproduces once every ten years? Why? (10 pts) The more rapid reproducer would be less likely to go extinct. Evolution happens via reproduction. Without much reproducing during the environmental change, there is little chance of the once every ten year species being able to survive.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
