If you failed to use correct aseptic technique by not sterilizing the loop before picking up the bacterial sample for the smear, what results may be seen under the microscope? A Both blue and purple cells may be seen on the slide. B No cells may be visible on the slide. C There may be cells of different shapes, sizes, and arrangements.
