#Unit 9. Diversity of Life Forms
  1. simple organic compounds can be synthesized in the laboratory from inorganic precursors, but complex organic compounds like carbohydrates and proteins can only be synthesized by living organisms.
  2. living organisms can be understood in terms of the same physical and chemical laws that can be used to explain all natural phenomena.
  3. although a life force, or vitalism, exists in living organisms, this life force cannot be studied by physical or chemical methods.
  4. living organisms are composed of the same elements present in nonliving things, plus a few special trace elements found only in living organisms or their products.
