The FDA regulates color additives used in food and dietary supplements marketed in the United States. FDA is responsible for making sure all foods containing color additives are safe for consumption, contain only approved ingredients, and are properly labeled.
Mitosis occurs only in eukaryotic cells and the process varies in different organisms. For example, animals undergo an open mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi undergo a closed mitosis, where chromosomes divide within an intact cell nucleus.
Sex Cell Production. Human sex cells are produced by a two-part cell division process called meiosis. Through a sequence of steps, the replicated genetic material in a parent cell is distributed among four daughter cells. Meiosis produces gametes with one-half the number of chromosomes as the parent cell. Because these cells have one-half the number of chromosomes as the parent cell, they are haploid cells. Human sex cells contain one complete set of 23 chromosomes. There are two stages of meiosis: meiosis I and meiosis II.
