Answer:
All the planets besides Earth lack a breathable atmosphere for terrestrial beings, but also, many of them are too hot or too cold to sustain life. A “habitable zone” which exists within every system of planets orbiting a star. Those planets that are too close to their sun are molten and toxic, while those that are too far outside it are icy and frozen.
But at the same time, forces other than position relative to our Sun can affect surface temperatures. For example, some planets are tidally locked, which means that they have one of their sides constantly facing towards the Sun. Others are warmed by internal geological forces and achieve some warmth that does not depend on exposure to the Sun’s rays.

Answer:
fertilization.
Explanation:
During fertilization, male and female gametes are fused to form a zygote. The male gametes in humans are called sperms. Sperms are formed by meiosis in sperm mother cells and have a haploid number of chromosomes (n=23). Similarly, the female gamete in humans is an egg which is a product of meiosis and is haploid (n=23). The fusion of these two haploid cells occurs in the oviduct of females in humans and form the diploid zygote with 2n=46. This process is called fertilization.
