B. fluorescence micsoscopy can be used with live specimens

C. fluorescence micsoscopy can be used with an electron microscope

D. fluorescence micsoscopy is less expensive and easier to use

Answer 1

The answer is B . there are many stains that are called vital stains in that they may be used in living cells and cause little or no damage to normal operations . Fluorescence is much more sensitive than normal colorimetic evaluations ..and if chosen correctly, some fluorescence assays can detect 10^-15 M of certain cell cycle intermediates , etc . There are available on the market many flurophores that can be used to track ion or molecule movement  into and targets inside cells.
