Microscopes are important tools. But do you know the difference between there microscopes and when to use each type? The compound light microscope combines the power of lenses and light to enlarge the subject being
viewed
The stereo microscope allows an object to be viewed three-dimensionally under the lenses
Very small, Live cells, like bacterial cells should be viewed using a scanning electron microscope.
The scanning electro microscope produces high-resolution, sharp, black and white 3D images.
If your task was to dissect the mouth parts of a grasshopper, you would use a compound light microscope
to assist you
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a
beam of electrons rather than a beam of light.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

since there are no options posted i'll give you a few examples.
