• Unit 1: Introduction to Biology

    Biology is the study of life. This unit will introduce to you major topics that a biologist studies and the major theories he or she uses and applies in his or her work. Hopefully, this is where you will begin to develop an appreciation for the scope of topics that biology addresses.

    Completing this unit should take you approximately 4 hours.

    • Upon successful completion of this unit, you will be able to:

      • list the basic characteristics of life that are common to all living things;
      • list the levels of organization of life and characteristics of each level; and
      • describe the steps of the scientific method and the importance of using the scientific method in research.

        Watch this lecture. At the 30-minute mark, the lecturer misspeaks and says that "thymus enlarges". The thymus is a small organ in the upper chest involved in the immune system. The lecturer meant to say "thyroid" when referring to a goiter in the neck. The last portion of the lecture (properties of water) will be covered later on in unit 3.
