The simple answer is that I don't know. I'm a middle school social studies and English teacher. I know little about science.
Ok but you could of said something instead of leaving me hanging waiting for you to answer.
Sorry -- but my ESP didn't detect that you were waiting for ME to answer. We have several science tutors on Jiskha -- although none of them specialize in biology.
Ok not necessarily you but other tutors.
