Ap bio. Need help on Evolution. Exam on Monday!!!! MULTIPLE CHOICE?

hehehe My AP Bio Exam is monday too! Well I guess everyone's is....Sorry though. Can't help you. My teachers retarded, so he stayed home from school this past week and this current week before the exam so we were forced to get two other teachers to teach us everything this week. We had 2 semesters of AP Bio and all we learned was 'enzymes lower the activation energy.' Needless to say we're not gonna be making 3s...
