We welcome and appreciate your contributions, but your recent edits to IB Biology/The Chemistry of Life ‎ had to be undone. Please see What is Wikibooks? to learn more about what contributions are beneficial to Wikibooks. Wikibooks is not a collection of links; nor should it be used as a platform for advertising or promotion, and doing so is contrary to the goals of this project. Because Wikibooks uses nofollow tags, external links do not alter search engine rankings. If you feel a link or content should be added to a page, please discuss it on the page's talk page before reinserting it. Please take a look at the welcome page to learn more about contributing to this project. Thank you. – Adrignola talk 01:29, 23 July 2010 (UTC)
