Answer:
Radiation leads to mutations that causes genetic drift and decrease fitness.
Explanation:
Radiation is responsible for changing or altering the DNA sequence within a cell.
Radiation either causes mutation or it leads to cell death.
Most of the ionizing radiation causes mutation within the deep inside of our cells which eventually leads genetic drift which means change in the frequency of the allele in a population over time.
Beneficial mutation confer advantage to the organism. But in this case, the mutation is not beneficial and decreases the fitness of the rodent organisms.
Answer:
The answer is D
Explanation:
The statement is telling us about the moment when the lineage of chimpanzees and humans separated from other primates, it is not telling us which trait or characteristic is superior.
Of the options given, the one that comes closest to the logic and coherence of the statement is option D, since it confirms the statement that possibly until 55 million years ago the lineage that produced chimpanzees and humans had not yet been separated from others primate lineages.
It is A.

The answer would be : <span>It is a well supported explanation which cannot become a law.
A law and a theory are different you know. In fact, the law is universel. This applies for everything unlike a theory which explains in particular why something is happening.
Any doubts ?
Hope this helps !
