A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

<span>As explained above, a cell which has yet to commit to meiosis is diploid. That is, it has 2n chromosomes. When it commits to meiosis, it doubles its DNA, becoming 4n. Then it goes through two rounds of cell division: during meiosis I, it divides into two cells and each of these cells is 2n. Then, during meiosis II, each of the two daughter cells divide again, producing a total of 4 haploid (that is, 1n) gametes So it would be A. Meiosis 1 hope i helped</span>
