It is likely to be a black hole though this has yet to be confirmed.
No. The super massive black hole at the center of the galaxy has about 4 million times the mass of the sun while the galaxy as a whole has at leas 1 trillion solar masses. In other words the black hole at the center of the galaxy accounts for about one twenty-fifth of one percent of the galaxy's mass.
Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.
Spirals.
The solar system is the Milky Way galaxy, Earth, and all other planets and galaxies are the solar system.
The black hole at the center of our galaxy, the Milky Way, is about 26,000 light-years away from Earth. It is known as Sagittarius A* and has a mass equivalent to about 4 million times that of our sun.
Harlow Shapley determined the center of the galaxy by studying the distribution and motion of globular clusters. By observing the positions and velocities of these clusters, he discovered that they were not evenly distributed in the sky but rather congregated towards a point in the constellation Sagittarius, indicating the center of the galaxy.
Astronomers believe a supermassive black hole lies at the center of the Milky Way galaxy because of the high speeds of stars and gas near the center, as well as the intense radiation emitted from that region. These observations suggest the presence of a massive object that can only be explained by a supermassive black hole.
Probably the same as the center of YOUR galaxy.

At the center of every galaxy is a supermassive black hole.
Yes, there is a very large black hole at the center of our galaxy. It has a mass of about three million suns and is very far from Earth at a distance of about 24,000 light-years. Huge black holes are thought to occur naturally at the center of most large galaxies and many have already been detected. The black hole which lies at the center of our galaxy is much too far away to be of any danger to Earth.

A spiral galaxy
Our solar system lies about halfway out (roughly 27,000 light years) from the galactic center, on a spur of the galactic arm called the Orion Arm, or sometimes called the Orion spur or simply "local spur".
Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.
BL Lacertae is the active center of an elliptical galaxy.
