A NATO official, speaking on condition of anonymity, pointed out that after the attacks NATO sent AWACS planes to patrol American skies and deployed a third of the troops in Afghanistan for more than a decade; more than 1,000 soldiers from non-U.S. NATO allies and partners were killed there, the official pointed out.
Cells in the human body have 46 chromosomes, including 22 pairs of autosomes and one pair of sex chromosomes (XX in females, XY in males). Because there are two sets of chromosomes, one from each parent, the cells are considered diploid.
Sex cells (gametes â eggs and sperm) have only one set of chromosomes (in humans, 23) and such cells are known as haploid (n) . Each cell is unique, as it is produced by meiosis (though the âmother cellsâ for the gametes are produced by mitosis, the final division is always meiotic).ex cells (gametes â eggs and sperm) have only one set of chromosomes (in humans, 23) and such cells are known as haploid (n) .
