Final answer:
The nucleus of a dividing cell and a non-dividing cell differ in the visibility of chromosomes and nucleolus.
Step-by-step explanation:
When comparing the nucleus of a dividing cell with that of a non-dividing cell, several differences can be observed. One major difference is the presence of condensed and visible chromosomes in the nucleus of a dividing cell, whereas the non-dividing cell usually has the chromatin in a more dispersed and less visible state. Additionally, during cell division, the nucleolus, responsible for producing ribosomes, becomes less prominent or disappears completely. In contrast, the nucleolus is typically visible and active in a non-dividing cell.
