Agroup of scientists is studying the internal parts of a cell. which microscope is most appropriate for these scientists to use?

a. simple
b. electron
c. light
d. compound

The most appropriate microscope for studying the internal parts of the cell is ELECTRON MICROSCOPE. The correct option is B.
Electron microscope, which is a compound microscope is usually used to study the internal environment  of the cell because of the easiness with which one can easily distinguish the cell organelles from one another. Electron microscope gives great clarification of the cellular components and allow scientists to observe minute details about cellular structures. Electron microscope usually magnify specimens to one million times of their real sizes. 

If a group of scientists are studying the internal parts of a cell, the microscope which is most appropriate for these scientists to use is the electron. The correct answer is B.

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
