Which lists three living units of the human body in order from the simplest to the most complex level of organization?

Three living units well of course the most simple is Cells, then Tissues, and finally Organs. Unless you are wondering about Protons/Electrons/Neutrons, then Atoms, then Molecules, then Elements...

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
