They are usually lighter because they are "open" and busy making ribosome subunits. There is usually only one nucleolus.
This is probably a nucleolus, one or more of which are in every nucleus.
I believe that would be the nucleolus.
Plants and animals need a nucleus because it houses the genetic material (DNA) that controls their growth, development, and functioning. The nucleus also regulates the cell's activities by controlling the expression of genes. Additionally, the nucleus protects the DNA from potential damage or interference.
Red blood cells lose their nucleus at maturity. It is kicked out, lost or nuked (depending how you want to call it) to make more room for hemoglobin. The nucleus makes as much as possible, packs it in tight and then is lost. Because the nucleus is gone, the cell can not repair itself and will get tattered and rather worn out in about 120 days. It will be recycled.
Yes, Niels Bohr inferred that the nucleus contains a positive charge based on his model of the atom, which he developed in 1913. In Bohr's model, electrons orbit a central nucleus, and for the atom to be electrically neutral, the nucleus must contain a positive charge that balances the negative charge of the electrons. This concept was further confirmed by later experiments and the development of quantum mechanics, leading to the understanding of protons and neutrons within the nucleus.
