a scientist plans to use a microtome to cut sections of a particular type of tissue so then that typical cell will be cut into about 20 sections. to help him make careful observation of internal cell structures, he considers staining the sections with a dye. which of the following procedures would give the most complete pictures of the internal stuctures of a cell?

1) look at one section
2) look at 20 sections from 20 different pieces of tissue
3) stain all the sections then look at 20 sections from 20 different pieces of tissue
4) look at 20 consecutive stained sections of a cell from the same piece of tissue
5) either b or c would be equally good procedures to ensure observation of the complete internal contents of a cell.
