While they can see the dorsal surface of the spider mite with their naked eye, they cannot see the mite clearly. The researchers are writing a grant to provide support for a microscope to use to
study these new mites. They need to purchase a microscope with a high magnification to observe the new mites on their habitat. Based on the information given, what type of microscope would you suggest? A. scanning electron microscope B. no microscope is powerful enough to see the smaller mite C. binocular compound light microscope D. transmission electron microscope
