Answer: Other than electron microscope rest all the microscopes like darkfield,phase contrast , fluorescence, polarizing, brightfield are variations of Light Microscope. Light microscope is an microscope that is used to visualize objects not visible by naked eyes .This microscope uses light and magnifying lenses to see the objects more precisely. The main principle behind all the variations of light microscope is the light emitted that can be either polarising,bright field, or the difference in the phases as in case of phase contrast microscope. All the variations of light microscope uses light as a main source to identify and magnify objects.Electron microscope uses a beam of electron to focus on the specimen.

Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make <u>glucose</u>, <u>acetic acid</u>, <u>amino acids</u> and <u>lipids</u>.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
