Which evidence supports the big bang theory? Select three options,
Many galaxies exist.
Planetesimals form in debris disks.
Most galaxies are moving away from us.
Uniform background radiation is detected in every direction
Galaxies spin faster than they should based on visible matter.

Explanation:

The big bang is a physical theory that explains how the universe we know came into being. This theory states that the universe was generated from a particle that has expanded and continues to expand today. all this expansion allows several galaxies to be scattered throughout space, in addition to allowing these galaxies to move away from each other.

The Big Bang theory also states that atomic nuclei existed at the beginning of the universe and that these nuclei must have left a trace of their existence as a detectable range of radiation. This can be proven by stating that uniform background radiation is detected in all directions.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
