The correct answer is option (A) to discover new aspects of the natural world.
The study of rock formations and living organisms in previously unexplored water habitats helps a scientist to discover the newer aspects of the natural world. The unexplored water habitats are the best source to understand the newer aspects of the aquatic bodies like the new species of plants or animals, factors affecting the aquatic life and the different types interactions in the habitats. The study of rock also helps in the study of plants and animals, which were once a part of the habitat, now in the form of fossils.
Thus, the study of rock formations cannot explain the recently observed phenomena as they help in the study of fossils. The study of living organisms in previously unexplored water habitats cannot be applied to test the conclusions of prior investigations and test the predictions of current theories as they remained unexplored.
Their becoming less frequent
Answer:
A new mutation
Explanation:
A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.
However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.
