We have Protons and Neutrons in the nucleus of an atom, Protons are positively charged, neutrons are non-charged particles.
5 Paramecium could be accommodated in this FOV.
Explanation:
FOV refers to the field of view of the microscope.
It is the maximum length or area of specimen you can observe in a single view.
If a single paramecium occupies 20 % of the Entire FOV.
Then the number of paramecium that will be accomodate 100% of FOV will be given by ,
Paramecium.
which is equal to 5.

Explanation:
These first type of experiments where crucial to advance in DNA knowledge.
In one experiment, they treated the material with enzymes that destroy all proteins.
