Our universe is made up of 23 percent is made up of dark matter, which is likely composed of one or more species of subatomic particles that interact very weakly with ordinary matter, and 72 percent is made of dark energy, which apparently is driving the accelerating expansion of the universe.

5. Option B: the Cosmological Principle

6. Option B: One that can communicate over interstellar distance.

7. Option C = Carbonaceous Chondrite. Unlike most meteors, these are high in carbon, which is what earth life is made from. They are also the rarest kind of meteor because carbon burns and most meteors are heated to thousands of degrees as they fall through the atmosphere.
