Answer: Bacteria and yeast because they are both made up of one or
more cells
◉ How would you evaluate an unknown specimen to determine if its
living? Answer: I would determine if something is living based off of its
structure. Is it made up of one or more cells?
◉ If the cell were the size of our lecture hall, how would you explain to
