The question is long and not easy, but here it comes:
A microtone is an instrument used to cut very thin, consecutive sections through a tissue so that the tissue's component cells may be examined under a microscope. A scientist plans to use a microtone to cut sections of a particular type of tissue. He wants to cut them so thin that a typical cell will be cut into about 20 consecutive sections. To help him make careful observations of internal cell structures, he consider staining the sections with a dye. Which of the following procedures would give the most complete picture of the internal structures of a cell?
a) Look at one unstained section
b) Look at twenty unstained sections from twenty different pieces of tissue
c) Stain all of the sections, then look at twenty sections from twenty different pieces of tissue
d) Look at twenty consecutive stained sections of a cell from the same piece of tissue
e) Either b or c would be equally effective procedures to ensure observation of the complete internal contents of a cell
