Hello everybody!

After a lot of time and research (about 48 hours to be exact) I have finally completed my biology final!!! I really hope you enjoy it and learn as much as I did. Throughout my research, I used several Internet sources as well as the book "Modern Biology". Below is a complete book source.
Postlethwait, John H and Janet L, Hopson "Modern Biology" Orlando, Austin, New York, San Diego, Toronto, London; Holt, Rinehart and Winston, 2006.
Enjoy and please leave a comment!
