With a light microscope one can view the nucleus and endoplasmic reticulum, large vacuoles etc
The resolution of a light microscope is dependent on the wavelength of light that is the main beam of illumination. Light has approximately 0.4 um (UV)- 0.7um (Infrared) wavelength. Organelles smaller than about 0.5 um will be difficult to discern with a light microscope.
With an electron microscope one can view, in addition, even the ribosomes and mitochondria, chromosomes, tubules etc.
An electron microscope can discern very minute details of a cell. This is because its resolution is dependent on the very small wavelength of a beam of electrons which is approximately 0.002 um (about 10,000 times powerful than a light microscope)
Answer: The ocean is one of Earth's most valuable natural resources. It provides food in the form of fish and shellfish about 200 billion pounds are caught each year. It's used for transportation both travel and shipping. It provides a treasured source of recreation for humans
Explanation:
The evolutionary selection process for glycogen metabolism<span> reflects the requirements of rendering large amounts of glucose into an osmotically stable but readily soluble </span>substrate<span> for rapid mobilization. Therefore glycogen </span>serves<span> as a glucose reserve and </span>substrate<span> buffer for local </span>energy<span> demand.</span>
