Essentials of the Living World 3rd Edition Selected Chapters 1-20

This book contains chapters 1-20 of Essentials of the Living world. I used it last semester for biology and Got an A, but at the very end(last week of class there were a few concepts I had to look up that were not in the book. Its in good condition. The front cover has a few creases and the corners are bent, but it worked well for me!
