Food pyramid (nutrition) A food pyramid or diet pyramid is a pyramid-shaped diagram representing the optimal number of servings to be eaten each day from each of the basic food groups. The first food pyramid was published in Sweden in 1974.
Before partitioning can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion. The alignment of replicated chromosomes and their separation into two groups is a process that can be observed in virtually all eukaryotic cells. Interfase must happen before mitosis can begin. Interfase is when the parent cell stores energy and becomes bigger so it can make the two daughter cells. Source(s):
Mitosis is the cycle that eukaryotic cells go through in order to divide. During mitosis, a cell duplicates its DNA and divides into two genetically identical cells. Mitosis is typically followed by cytokinesis, which divides the other properties of the cell including cytoplasm, organelles and the cell membrane. Karyokinesis also occurs, which divides the nucleus.
