Answer:
The correct answer to the following question will be "Mihrab".
Explanation:
- A semicircular niche throughout the wall of a mosque showing the qibla; that is, the direction of the Kaaba in Mecca, and hence the way that Muslims will face while they pray. Thus the wall into which a mihrab appears was the "qibla wall."
- A chanter calling for people to pray. Fana is a religious figure; in fact, a few of Muhammad's hereditary predecessors, worshiped in Shiite Islam.
- It is traditional, when entering a mosque, to remove somebody's shoes and put them on the entrance rack. This is accomplished out of respect and also to avoid soiling the interior floor of the prayer hall — prayer halls do not have chairs or benches, just row after row of carpets, aligned to face the holy sites of Mecca in Arabia.
Because it has to be that way
Abiogenesis is the theory that life arose from non living molecules to form the earliest life forms. In the simplest sense, once there is life, life will arise from living rather than non living matter. However, there are those who speculate that it is possible for abiogenesis to occur more than once.

Answer:
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive.
Stars start their lives as clouds of dust and gas. Gravity draws these clouds together. A small protostar forms, powered by the collapsing material. Protostars often form in densely packed clouds of gas and can be challenging to detect.
"Nature doesn't form stars in isolation," Mark Morris, of the University of California at Los Angeles (UCLS), said in a statement. "It forms them in clusters, out of natal clouds that collapse under their own gravity."
Smaller bodies — with less than 0.08 the sun's mass — cannot reach the stage of nuclear fusion at their core. Instead, they become brown dwarfs, stars that never ignite. But if the body has sufficient mass, the collapsing gas and dust burns hotter, eventually reaching temperatures sufficient to fuse hydrogen into helium. The star turns on and becomes a main sequence star, powered by hydrogen fusion. Fusion produces an outward pressure that balances with the inward pressure caused by gravity, stabilizing the star.
How long a main sequence star lives depends on how massive it is. A higher-mass star may have more material, but it burns through it faster due to higher core temperatures caused by greater gravitational forces. While the sun will spend about 10 billion years on the main sequence, a star 10 times as massive will stick around for only 20 million years. A red dwarf, which is half as massive as the sun, can last 80 to 100 billion years, which is far longer than the universe's age of 13.8 billion years. (This long lifetime is one reason red dwarfs are considered to be good sources for planets hosting life, because they are stable for such a long time.)
