Exactly what your blood sugar level should be two hours after meals is up for debate. As of 2015, ACE guidelines call for the tightest control, with two-hour readings below 140 mg/dl. The Joslin Diabetes Center and the American Diabetes Association suggest postmeal readings below 180 mg/dl.
Reproductive cells, or gametes-sperm and eggs-have half as many chromosomes as somatic cells, or one set of 23 chromosomes in humans. The number of chromosomes in somatic cells varies widely among species: 18 in cabbage plants, 48 in chimpanzees, 56 in elephants, 90 in hedgehogs, and 148 in one species of alga.
Sexually reproducing species have somatic cells (body cells), which are diploid [2n] having two sets of chromosomes (23 pairs in humans with one set of 23 chromosomes from each parent), one set from the mother and one from the father. Gametes, reproductive cells, are haploid [n]: They have one set of chromosomes.
