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.
There are two major differences between mitosis and meiosis. First, meiosis involves not one, but two cell divisions. Second, meiosis leads to the production of germ cells, which are cells that give rise to gametes. Germ cells are different from somatic cells in a critical way. Whereas somatic cells are diploid, meaning they have two copies of each chromosome, germ cells are haploid. The haploid nature of germ cells is vital to the process of sexual reproduction. There are two different sex cells or gametes: sperm and eggs. Males produce sperm and females produce eggs.
