Black holes are created when a large star collapses when they run out of nuclear fuel.

C) A population bottleneck occurred, altering the resulting allele frequencies.
Explanation:
Population bottleneck can be described as the reduction which occurs in a population due to any environmental factor like fire or due to the activities of humans like hunting etc.
A large number of Beatles got killed due to the fire. The reduced population that is left has an altered gene frequency. This phenomenon can be described as a genetic drift that has occurred and caused changes in the genetic frequencies.

The environmental factors that would be more important to a rain forest plant would be sunlight and carbon dioxide (for sure). This is because rain forests are more shady and there would be less sunlight for the plant to get, which could cause the plants to get taller in order to reach the sunlight (which they do). However, in the desert, the plants would be more dependent on water and carbon dioxide. This is because the plants have more sunlight and therefore aren't struggling to find it, but since deserts are fairly dry, it would be harder for the plants to have water.
