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):
Control of Cell Division. Cell division usually limits itself, namely at certain checkpoints during the cell cycle. The majority of cells in the human body exist at the G0 stage of interphase, which denotes the state of nondividing cells. A cell will continue into the mitotic cycle if it receives a signal at the G1 checkpoint telling it to divide.
