Magnetic forces act at a distance. The opposites attract and pull each other closer
B.) the universe may continue to expand
C.) stars could burn out , causing the universe to become dark and cold
D.) gravity could pull galaxies back together causing a reverse of the Big Bang
Answer:
B.) the universe may continue to expand
Explanation:
The steady state theory which states that the universe was, is and will be the same, has been discredited by two physicists who found the leftover energy from the big bang.
If you are listening to FM radio, you might have heard some static noise while changing stations, that noise is from the leftover energy from the big bang. This energy is called the dark energy.
The dark energy tries to rip everything apart while gravity tries to hold everything together.
It was observed that the dark energy is stronger than gravity.
The distance between the galaxies is increasing. This proves that the dark energy successfully defeated the gravity and expanted two massive objects in the universe.
Because of this dark energy the universe will continue to expand.
Note: Dark energy is also increasing the distance between protons in atomic nucleus in every atom in our body too. Chilly right?
the answer is B! it would continue to expand.....just took the test XD

Explanation:
The Bacteria and Archaea domains are prokaryotes, they contain no nuclues or organelles, only a circular chromosome. They cannot form multicells organisms. Archaea can be found in extreme evironments, such as hot springs and deep sea vents.
