When you ask a "Which of the following..." question, you need to offer some choices. We're unable to read your mind, to know what distractors were on your quiz.
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
Have no real effect on the merging "colliding" galaxies
These small galaxies are believed to be the result of collisions between larger spiral galaxies. During such collisions pieces of the spiral arms get flung out into space, becoming small irregular galaxies.
Spiral galaxies get their beautiful structure from tidal interactions between galaxies.
They happen as a result of the interactions between the laws of nature.
Yes, there are. These generally come about when they are ejected from their host galaxy by the huge gravitational interaction involved in the collisions of galaxies.
Pneumatology is the study of spiritual beings and phenomena, especially the interactions between humans and God.
There's nothing between the galaxies. It's just other galaxies that float around the universe.
The space in between galaxies is far larger than the galaxies themselves.
rate of collisions between particles. average velocity of the particles.
A peculiar galaxy is unusual in its shape, size, or composition.They are formed as a result of interactions between galaxies and the massive gravitation forces, twist them into unusual shapes.See related link for more information
What was the result of collisions between the early Earth and other, smaller protoplanets?
