The resulting product is a black, odorless powder. The charcoal is then activated through a special process that makes lots of holes and crevices on the charcoal particles to increase surface area and available binding sites. One teaspoonful of activated charcoal has about the same total surface area as a football field!
No: 22. Mitosis: Two chromatids of a chromosome (Progeny cells) are genetically similar. The genetic constitution of the daughter cells is identical to that of the parent cells. Meiosis: Two chromatids of a chromosome (Progeny cells) are often genetically different due to crossing over. The genetic constitution of the daughter cells differs from that of the parent cell. The chromosomes of daughter cells usually contain a mixture of maternal and paternal genes.
The second cell division in Meiosis is known as Meiosis II. Meiosis II is very similar to Mitosis. In both cases chromosomes line up and sister chromatids are separated by the action of the spindle fibers. The daughter cells are genetically identical to one another. There are some minor differences between Mitosis and Meiosis II. Cells at the start of Mitosis II are haploid. Cells at the start of have the normal ploidy of the organism they are in. Normally we think of Mitosis as occurring in diploid cells but in many organisms it can occur in haploid cells as well.
