Extreme disturbances are complex events. The terminology used to identify them, such as 'hurricanes,' 'fires,' 'economic collapse,' 'war,' or 'drought,' is insufficient for advancing understanding about how they interact with, and affect, ecosystems, including SETS.

What cellular structures can be observed with the aid of light microscopy and electron microscopy?​
Serjik [45]

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)

What is the function of RBC
avanturin [10]

Answer:

When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.

The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.

There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.

Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water
