I've posted previously links to individual Khan Academy's YouTube videos before, but now Khan Academy has a slick new website with all of their educational videos with online discussion threads for each video. You can view videos and ask questions or view common questions and answers already asked.

So, you want to learn biology online, but still like the old paper-in-hand copy to read? No problem! Open Stax College has a collection of college science textbooks you can view online for free or download for a small donation that you decide on. These are peer-reviewed texts written by professional content developers. Open Stax College was created by Rice University and has several open source textbooks with more on the way.
