Which of the following statements best provides evidence of the big bang theory?
Oxana [17]

Answer: D. Galaxies show a red shift, indicating they are moving away from each other.

Explanation:

Galaxies seem to show a red shift which indicates that the galaxies are moving away from each other. This provides evidence for the Big Bang theory because the theory posits galaxies will keep moving away from each other.

This is because when an explosion happens, matter moves away from the point where the explosion happened. If the Big Bang happened therefore, galaxies will move away from the source which is why galaxies are moving away from each other.

A dog breathes out CO2 and a tree releases O2. How are the dog and the tree connected in the oxygen cycle?
Hitman42 [59]
A dog breathes in oxygen and then releases carbon dioxide when he exhales. Conversely, a tree gives off oxygen and takes in carbon dioxide. So the breath of the dog sustains the tree while the output of oxygen for the tree sustains the dog.
