7. In your biology lab you need to estimate the proportion of dead cells in a suspension. You need to pick a random sample from the suspension, so you stir it very well, then using a pipette you take a sample from it and put some special dye in it. The dye turns the dead cells blue. As you look in a microscope, six of the 85 cells you look at are dead. a. What is the parameter of interest?...

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
