Which evidence supports the big bang theory? check all that apply 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.

1. Most galaxies are moving away.

2. Uniform background radiation is detected in every direction.

Explanation:

Big Bang Theory describes the beginning of the universe. According to the theory, the universe was confined at a point having infinite density and extremely high temperature. With the Big Bang about 13.7 billion years ago, the universe started expanding and cooling down. The evidence that supports the Big Bang Theory is:

1. The red-shift of the galaxies: Most galaxies are moving away from us. Since the universe started expanding 13.7 billion years ago, on larger scale, all the galaxies are observed to be moving away. The spectrum of the galaxies shows red-shift.

2. Uniform background radiation can be detected in every direction. It is considered to be remnants of early stages of universe.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
