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.

Answer:
1 day.
Explanation:
From the given information:
The rate of mutation induced by RNA polymerase is:
Since the genome comprise of 19000 bp;
To complete a single replication, the viral cycle induce: 
However, in a single day; 10,000,000,000 viruses are reported to be replicated.
Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:
SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.
The answer to this question would be: oxygen
The presence of oxygen allows the cell to do the aerobic reaction. Using in metabolism will result in a much higher number of ATP produced.
When there is no oxygen, the cells make energy using the anaerobic reaction that gives a low number of ATP.
Sunlight is the main change! sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!
