Comets travel in orbits around the Sun. Some comets take less than 200 years to orbit the Sun. They are called short-period comets. Short-period comets are thought to originate in the Kuiper Belt, which is a belt of icy objects just beyond the orbit of the planet <u>NEPTUNE</u>. The dwarf planet <u>PLUTO </u>is located in this belt.
Explanation:
Comets are composed of ice, dust and gas. Comets are categorized into two kinds: short period comets (P < 200 years) which come from Kuiper belt and long period comets (P >200 years) come from Oort clouds.
Kuiper belt resides beyond the orbit of the planet Jupiter. Kuiper belt contains many objects Comets, asteroids and dwarf planets. Pluto which is a dwarf planet is located in Kuiper belt. Earlier it was considered as a planet but demoted to a dwarf planet in 2006.
Each human cell is diploid (2n) and possesses 23 pairs of chromosomes. Out of 23 pairs, 22 pairs are autosomes and 1 pair is sex chromosomes. Sex chromosomes are designated by alphabet X and Y. In human females, each cell has two XX chromosomes, whereas males have one X and one Y sex chromosome.
The sun gives off light energy to plants. Light is required for plants to perform photosynthesis. And the plant provides nutrients for organisms such as humans. Some of those other organisms the plant provides nutrients for, we humans consume.
