Answer:
Potassium-40
Explanation:
Potassium-Argon dating is the most efficient radioactive dating method in order to determine the absolute age of the fossils. It involves the decay of unstable Potassium-40 (K-40) into a stable Argon-40. The half-life of this Potassium-40 is approximately 1.3 billion years, so it is very much helpful to date the rocks that are of about 4.6 billion years to 100,000 years old.
Thus, the K-40 radioactive isotope would be the best to determine the exact age of the fossil that is found in the rocks that are about 600 million years old.

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)
