In mitosis, the important thing to remember is that the daughter cells each have the same chromosomes and DNA as the parent cell. The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes. Since the daughter cells have exact copies of their parent cell's DNA, no genetic diversity is created through mitosis in normal healthy cells.
In Conclusion. The core difference between narrative and expository essays is their style. While narrative paper allows the author to be creative and tell a story in a way he or she likes, expository essays follow some strict rules that one must abide.
3Exposition (expository writing): Exposition is writing that explains or informs. It is a practical kind of writing (the kind you are reading right now!). Examples of expository writing include encyclopedia entries, news reports, instruction manuals, informative essays, and research papers.
