You have discovered a new microorganism,but you want to know if it is a eukaryote or a prokaryote.To investigate this question you prepare a slide with a simple stain and view it with a light microscope with a 40X objective lens and 10X ocular lens.You also prepare a control slide using Saccharomyces cerevisiae (a unicellular eukaryote).You can see the cells on your control slide,but you don't see cells when you look at your unknown microorganism.What can you conclude from this experiment?
A) The experiment failed to visualize the organism because the stain killed it.
B) Your new unknown microorganism is probably a virus.
C) The cells of the new unknown microorganism may be too small to see with the objective and ocular lenses you used.
D) The new unknown microorganism is probably an archaeon.

Since the cells of the new unknown microorganism were not observed, it is possible that they are too small to be visualized using the objective and ocular lenses used. This is a common problem in light microscopy and can be addressed by using higher magnification or alternative imaging techniques. The control slide, which showed visible cells, indicates that the staining procedure and microscope setup were adequate for visualizing cells of the proper size and composition, ruling out options A, B, and D.
