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)

How have scientists determined the earth's core is composed of iron and nickel?
Sedaia [141]
<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or radioactive dating is used, for example, rocks or carbon, in which trace radioactive impurities were specifically fused when they were framed. The strategy looks at the abundance of a normally happening radioactive isotope inside the material to the abundance of its decay items, which shape at a known consistent rate of decay.</span>
