The correct answer is B. competitive exclusion.
This law refers to the fact that it is nearly impossible for two species to exist in the same place at the same time together, if they are interested in the same resources. If both species need the same thing to survive, one will have to be stronger while the other one will dwindle in number.

The surface of the early Earth is often described as hellish by scientists. The high temperature is primarily attributed to the high levels of carbon dioxide in the atmosphere and the molten rock on the surface of the planet. However, these two aren't the only factors in play.
Another factor that contributed to the extremely high temperature of the early earth is radioactivity. Radioactive decay of the isotopes found underground plus the left over heat from the formation of our planet produced high levels of radiogenic heat.
There's also the kinetic energy from falling asteroids and meteorites. Massive amounts of energy in the form of heat and sound is produced when asteroids and meteorites hit the Earth. Also, the pressure waves that travel radially outwards the center of the impact is similar to the impact of an atom bomb. As such, dust particles envelop the atmosphere, trapping the heat from the impact.
The last factor is the gravitational contraction, it contributed to the hellish temperature of primordial Earth because the energy generated from such event is enough to trigger hydrogen fusion.
Answer:
Degeneracy
Explanation:
- There are 4 nucleotide bases and they can form a lot of different codons - about 64 different codons
- There are only 20/21 amino acids, not enough for each of the codons
As a result, codons have to "double up" and share amino acids because there is only a limited number of these that they can code for
