Welcome to the on-line forum for Biology 103.  This is a place for thoughts in progress, a place to leave thoughts and questions that others may find useful and find ones that you might find useful, a place for conversation.  Join in, and let's see what we can make of life together.  If you're registered for the course, be sure to sign in before posting.  Others are welcome to join in as well but posting of comments will be delayed to check for spam. 
You're free to write about whatever has struck you.  If you need something to get you started though, we've now wrapped up (for now) our discussion of molecules and macromolecules.  Have we been wasting our time?  Are observations at this level of scale irrelevant for understanding life or are they significant?  What have we been able to account for?  What can't be accounted for at these levels of scale, and so perhaps need observations at larger scales to make sense of?
