Tim is counting and identifying the white blood cells on a stained blood smear under a microscope with a mechanical stage. Several of the white cells are abnormal, so he lays the slide aside until later, when the doctor will be in and can view them. When he reinserts the slide, he has to search for 10 minutes to find the blood cells that he had viewed before. How could Tim have found the cells quickly on the second viewing? |
