Detailed explanation-1: -Which describes a characteristic that is shared by different galaxies in the Universe? They all formed because of gravity. Which correctly describes the gravity between objects in the solar system? Objects with a large mass pull more strongly than objects with a small mass.
Detailed explanation-2: -Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It makes it possible to use human-made satellites and to go to and return from the Moon.
Detailed explanation-3: -A galaxy is a huge collection of gas, dust, and billions of stars all held together by gravity. All galaxies are made up of these same things. However, they come in many different shapes and sizes.
