<span>The correct answer is "Absorption of rainfall by soil."
The hyrdosphere refers to all water on the earth's surface. The geosphere, in this context, refers to the solid parts of the earth (rocks, sand, etc.) Since rain is part of the hydrosphere and soil is part of the geosphere, rain soaking into the soil would be an interaction between the two. The other choices deal with changes in the hyrdrosphere, but there is no interaction with the geosphere.</span>

Answer: They evolve through genetic drift.
Explanation: <u>Junk DNA refers to noncoding sections of a genome</u>. It consists of repeated segments scattered randomly throughout the genome generated through transposition or movement of sections of DNA to different positions in the genome.
Genetic drift is the change in the frequency of an allele in a population due to random sampling of organisms. This process is caused by spontaneous mutations and may cause the alleles to disappear completely and thereby reduce genetic variation. <u>Many of these genetic alterations are in regions of "junk DNA"</u>
