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):
Cell Division Lab Austin Cao, AP Biology Part A: Getting started Mitosis is the process by which a cellâs nucleus. replicates itself. This is an integral part of the cell cycle that allows cells to quickly reproduce themselves. Meiosis is the process by which a cell splits its number of chromosomes in half into gametes used for sexual reproduction. 1. How did you develop from a single-celled zygote to an organism with trillions of cells? My cells simply underwent mitosis many many many times. 1+2+4+8+16... sum = 100 trillion. 2. How is cell division important to a single-celled organism? Cell division allows the organism to asexually reproduce. 3. What must happen to ensure successful cell division?
