Digestion is not dependent on gravity. Astronauts do fine in space.

You can live without the appendix, as it doesn't have a crucial function in digestion. Additionally, it is possible to survive without the gallbladder, as bile can still flow directly from the liver to the small intestine.
No, but the centre of gravity need not be inside the object. Not unless Gravity is not a variable. But it is not possible for an object to not have a center of mass.
As of now, manipulating gravity is not possible with current technology and scientific understanding.
no
It is possible if you get a machine that gives you more gravity.
Planets are held in orbit around a star by gravity. Gravity is the force of attraction between objects with mass, and it is what keeps planets in their respective orbits around stars like our Sun. Without gravity, planets would not be able to maintain their position in space.
It is possible, but not likely. Meteors have relatively small masses, without a large gravity well. They tend to lose them because they are in motion.
It is not possible for the center of gravity to be at a point where there is no mass, as it is a weighted average that considers the distribution of mass within a body. If there is no mass at a point, it cannot contribute to the calculation of the center of gravity.
No. We cannot alter gravity.
no, there is always gravity
