Bio Explained With Dr. W

Ho Everyone, I'm Dr. Wefer and  I've been teaching for over 20 years, I have my Ph.D. from Columbia (Teachers College), am a NYS Master Teacher Emeritus, but most of all I love talking about (and learning about) all subjects in Biology.  If you want to review topics, or if you simply LOVE Bio, please join me and my class.  Feel free to leave comments or ask questions.
