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.
All of the following statements comparing and contrasting mammalian mitosis and meiosis are correct EXCEPT a. both mitosis and meiosis involve the use of a spindle composed of microtubules. B. both mitosis and meiosis are followed by cytokinesis. C. both mitosis and meiosis are carefully regulated spatially and temporally. D. both mitosis and meiosis involve the process of crossing over at the time of prophase. E. both mitosis and meiosis involve a reduction in the DNA content of the daughter cells.
