Module 2 - Virtual Microscopy Activity (Questions and 100% correct answers)

The dissecting microscope is most useful for viewing correct answers The dissecting microscope is used for examining organisms or objects at relatively low magnifications (organs and tissue) Limitations of the dissecting microscope are correct answers If you need high magnification, this is not the microscope for you to use The dissecting microscope works by correct answers a beam of light is produced above the stage and reflects off of the specimen's surface, passing through the glass lenses that magnify the image. Describe in detail that can be seen under the dissecting microscope correct answers You can use it to view the surfaces and details of leaves, stems, mold, spores, or other small objects that can be seen with the naked eye but require magnification in order to be examined closely. The compound light microscope is most useful for viewing correct answers A compound light microscope is an instrument that uses visible light and magnifying lenses to examine small objects that are not visible to the naked eye, or in finer detail than the naked eye allows. (tissue samples, blood, microorganisms in a pond, microscopic cells, and some of the larger details within the cells.) Limitations of the compound light microscope are correct answers Properties of light limit the resolving power. They cannot resolve detail finer than about 0.2 micrometers and do not magnify beyond 1500 times the true size of the specimen. Because light microscopes are limited in resolve and magnification, biologists were not able to study the small details and complex structures inside cells until the development of electron microscopes. The compound light microscope works by correct answers the light source is below the stage, and the light shines up through the magnification lenses. You can prepare the specimen for viewing by placing it on a rectangular glass slide. It can be stained with a dye that adds contrast to nearly transparent cells. Describe the detail that can be seen under the compound light microscope correct answers Compound light microscopes can be used to view tissue samples, blood, microorganisms in pond water, microscopic cells, and some of the larger details within the cells. the SEM is most useful for viewing correct answers can be used to see specimen in great detail - mainly used for studying the internal structures of cells that cannot be viewed under light microscopes limitations of the SEM are correct answers you have to coat the specimen in a thin layer of gold or metal so that the electrons bounce off of its surface
