BIO101: Introduction to Molecular and Cellular Biology

Watch this lecture, which discusses the unifying themes of biology. We will cover the last portion of the lecture which describes the chemistry and properties of water in Units 2 and 3. Note that the lecturer later apologizes for saying the "thymus" enlarges when she had meant to refer to the "thyroid" when describing a goiter in the neck at the 30-minute mark of the video.
