For sexually reproducing diploid parent cells, which of the following statements best explains the production of haploid cells that occurs in meiosis but not in mitosis?Separation of chromatids occurs once, and there is one round of cell division in meiosis. ASeparation of chromatids occurs twice, and there are two rounds of cell division in mitosis. BSeparation of chromatids occurs once, and there are two rounds of cell division in meiosis. CSeparation of chromatids occurs twice, and there is one round of cell division in mitosis.

.B Separation of chromatids occurs once, and there are two rounds of cell division in meiosis.

Explanation:

At Anaphase II of second  meiotic division, separation of chromatids occurs, with the spindles microtubules pulling the chromatids to opposite poles.

The significance of  chromatid separation at  anaphase II of meiosis II, is  the formation of  haploid cells(n) which occupies the gametes of the parents.

Prior to this at anaphase I, the homologous chromosomes get separated and move to anaphase II to under go centromere separation as described above.

This is a complete difference to mitosis which consist of one cycle, with the separation of chromosomes and not chromatids at single anaphase cycle.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.
