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)

Solution A has a pH of 5, and Solution B has a pH of 6.
Leto [7]

Solution A has 10 times more hydrogen ions than solution B.. The correct option is B.

<h3>What is a pH?</h3>

pH is the potential of hydrogen ions, or measure of hydrogen ion concentration.

It is generally used to determine the acidity and basicity of the solution based on pH scale.

The pH scale is logarithmic, which means that each pH unit contains ten times the number of hydrogen ions as the unit above it. So solution A has 10 times more hydrogen ions than solution B.

Thus, the correct option is B.
