Sexual reproduction results in gametes that combine two cells from different individuals. Meiosis also produces gametes. Haploids contain one set of chromosomes in each of their cells. Diploids cells contain two chromosome sets. For plants, haploid and diploid cells divide via mitosis. The plants’ haploid phase is called the gametophyte, and the diploid phase is called the sporophyte.

Sporophytes are diploid plants that use meiosis to produce spores. These spores are haploid cells that grow into haploid gametophytes. Megaspores grow into female gametophytes, and microspores grow into male gametophytes.

Gametophytes are haploid plants that use mitosis to make haploid gametes. These gametes are female in the form of an ovum (egg) or male in the form of sperm.

“Pakistan would mean a massacre,” the Premier of Punjab Sir Sikandar Hyat Khan predicted to the distinguished civilian Penderel Moon as early as in October 1938 ( Divide and Quit, page 20). That was well before the Muslim League adopted the Pakistan resolution on March 23, 1940, in Lahore, radically altering Sir Sikandar's draft just 24 hours before it was passed. He repudiated it because it dropped the organic linkbetween the two parts of India, which he had provided. He told the Punjab Legislative Assembly, on March 11, 1941, “We do not ask for freedom that there may be Muslim Raj here and Hindu Raj elsewhere. If that is what Pakistan means I will have nothing to do with it.”

Nitrogen (N2) forms Three Covalent Bonds to become stable.

Here the Atmomic Number of Nitrogen is 7. Because there are 2 electrons in the first orbital and 5 in the second and you still have space for 3 more. So it shares, 3 to get the stable octet. Therefore, there are 3 covalent bonds in N2.
