Explanation / Answer
1. At high magnification, nuclei appears oval as it is in various stages of mitosis.
under high magnification microscope, it can be seen that chromatin threads are condensing and nucei is preparing for the cell division. This cannot be seen under simple microscope.
2. Size of RBC is about 10 micrometer
So, in human hair of dia 200 micrometr, 20 cells(10*20=200) can be adjusted
