Answer:
The correct answer is allopatric speciation.
Explanation:
Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.
So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.
The answer is A, earthquake. Typically, tsunamis can form after an earthquake. This happened in Indonesia a couple of times. I hope this helped! :-)
The answer to the question B which is the principle of dominance. Say the genotype of plant 1 is TT(tall, homozygous) and plant 2 is tt(short, homozygous). <span>T is dominant over t.
Crossing the two plants, we end with genotypes that all show Tt.
Since T is dominant it will show between the two, resulting in all tall plants.</span>
