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)
Out of the following given choices;
<span>A) </span>increase; increase B) decrease; increase C) increase; decrease D) decrease; decrease
The answer is A. Increased hunger causes an increased appetite that is due to increased episodes of hypoglycemia (low blood sugars). This is due to an increase in metabolic rate that breaks up glucose for energy at very high rates.
The correct answer is "C". 'Proton'. The number of protons is equal to the atomic numbers.
I hope this helps!
