Compare and contrast the structure and function of a compound light microscope and a scanning electron microscope. be sure to discuss the structure and function of each as well as the function and usefulness of each when examining a specimen. (5 points)

Both the compound light microscope and the scanning electron microscope are devices used for visualizing structures too small to see them with the eye. But, they differ in many ways. Some of them are:

* → The light microscope is compact, handy, and simple to use.
  → The electron microscope is large, complicated, and requires technical skills.

* → The light microscope can be used for observation of both live and dead specimens.
   → The electron microscope can be used for observation of only dead specimens.

* → The light microscope uses light rays for illumination of the specimens.
  → The electron microscope uses electron beams to view specimens.

* → The light microscope has a magnification of up to 1,500 times.
  → The electron microscope has a magnification of up to 1,000,000 times.

* → The light microscope has lenses made of glass.
  → The electron microscope has lenses made of electromagnets.

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
