Answer:
Because Circumpolar constellations are constellations that never set below the horizon when seen from a particular location on Earth.
They can be seen in the night sky throughout the year, while other constellations are seasonal, visible only at certain times of year.
The term circumpolar refers to constellations and stars that are circling the north and south celestial poles without ever dipping below the horizon. All circumpolar constellations are found near the celestial poles and, due to their proximity to the poles, they never disappear from view.
The five northern constellations visible from most locations north of the equator throughout the year are Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor.
The three southern circumpolar constellations visible from most locations in the southern hemisphere are Carina, Centaurus, and Crux.
Other constellations are just as prominent in the sky and can be seen for most of the year, but only these eight are circumpolar.

Because its a chemical bond that involves the sharing of electron pairs between atoms.
Making rough estimate of physical quantities is useful because it allow us to have an idea of how big or small a quantity is, it gives us the near result of the real quantity a matter contains. The approximate quantity obtained will give us information about the size of the quantity.
Answer: The daughter cells develop after the cell division will have unequal number of chromosomes.
Explanation:
The interphase is the stage of the cell cycle in which the parent cell prepares itself for division. It increases in size and develops organelles for cell division. Before the cell division the replication of the genetic material in the form of DNA is necessary so that both daughter cells receive equal amount of genetic material after the cell splits by mitosis. Mitosis is a cell division in which the parent diploid cell splits into two haploid daughter cells. Each daughter cell receives the half the chromosomes as that of the parent cell.
