At fertilization do haploid zygotes combine to form a diploid gamete

In land plants, the zygote is formed within a chamber called the archegonium. ... As the zygote divides and grows, it does so inside the archegonium. Humans. In human fertilization, two 1n haploid cells—an ovum (female gamete) and a sperm cell (male gamete)—combine to form a single 2n diploid cell called the zygote.

If you get a map and put the countries a states all together it forms all one piece you can also tell because of the earth quakes

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
