I think this is a shot in the dark, but worth a try. I have the Biology: Life on Earth by Audesirk, Audesirk & Byers 10th edition bought used online, apparently there are some pages missing in the book, so I can't do my homework, if anyone has the book could, you help me by posting the question on page 384 and 402, review question question 1 for both, please help me if you could. [*note when buying used books make sure all of the pages are there.]
