Scientists discover two populations of mice on either side of a major river. The two populations have almost identical genes, but the mice from one side cannot breed with the mice from the other. This is most likely because Select one:

both species of mice lived on both sides but owls killed one population on each side

the river separated one species of mice into two populations

two different species of mice migrated to the river from different directions

the similar habitat caused two species to become genetically similar

there really is life in the deepest part

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
