<span><span>All cells in a eukaryote are <span>diploid, except for germ cells</span><span>. </span></span><span>Germ cells<span> (gametes) have only half the number of chromosomes as a diploid cell—</span>one<span> of each pair—and are termed </span>haploid (n)<span>. In a human egg or sperm, there are </span>23 chromosomes<span>, one of which is an X or Y. </span></span><span><span>The number of chromosomes is reduced from </span>46<span> to </span>23<span> during the process of <span>meiosis. Fertilization of the egg by the sperm restores </span>the diploid number of </span>46 chromosomes<span>.
I should also clarify from your question that fertilization does not result from two ova; rather, it is an ovum and sperm.</span></span></span>
If an animal dies and falls into a river, and over time
sand, rock, and other material settle on top of the animal remains, <span>sedimentary rock will be most likely to form because of the layering. </span>
