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.
Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes.Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.Finally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one.his separation means that each of the daughter cells that results from meiosis I will have half the number of chromosomes of the original parent cell after interphase. Also, the sister chromatids in each chromosome still remain connected. As a result, each chromosome maintains its X-shaped structure.
