Adaptation
Adaption is the biological process by nature of fitting an organism to its environment.
The finches on the different islands share the same ancestral population that migrated to the Galapagos Islands. However, due to the different environmental conditions on the different islands, the population adapted variably to enable them survive on their respective islands.
Explanation:
Adaptation occurs by natural selection pressures on a population. The individuals with desired traits are more likely to reach maturity and pass down their genes the next generation (due to competition for resources). Therefore, over generation, there will be more and more individuals with these desired traits and fewer and fewer with undesirable traits. The population, therefore, evolves with time. In the case of the Finches this is called divergent evolution/radiation.

Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
Plasmids are small DNA fragments that occur in many bacterial cells.

In the
evolutionary sense fitness refers to the measure of reproductive success of an
individual or of organisms in general. Those organisms that leave the largest
number of mature offspring are the fittest. Fitness can be achieved through survival
or mortality selection, mating success or sexual selection, and family size or
fecundity selection. Fitness is critical for a species’ survival and is a major
adaptation that all organisms do through a long period of time. <span> </span></span>
