Question

What is a nucleus?
And how it works

Answer 1

Answer:

A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus

Answer 2

• The atomic nucleus is a tiny, compact area at the center of an atom that was identified in 1911 by Ernest Rutherford based on the Geiger–Marsden gold foil experiment of 1909.
• Soon after the neutron was discovered in 1932, Dmitri Ivanenko and Werner Heisenberg constructed models for a nucleus made up of protons and neutrons.
•  An atom is made up of a positively charged nucleus surrounded by a cloud of negatively charged electrons held together by electrostatic force.
• The nucleus contains almost all of an atom's mass, with just a minor contribution from the electron cloud.
• The nuclear force brings protons and neutrons together to create a nucleus.
