I am alive because I comply with the numerous properties of life that emerge from complex organization. This can be explained in terms of the hierarchy of biological organization-a pattern explaining the high degree of order evident in my existence. Atoms are identified as the basic building blocks of life. These atoms bond together into molecules and in turn bond together into complex molecules. Life is characterized by the existence of complex molecules.
Continuing upward in the hierarchy of biological organization, complex molecules cluster together into organelles to form part of a larger structure. These include a nucleus that carries g
