Well if you want the difference between the two one is where water naturally flows into the lowest point of elevation while a divide is just separating
two basins.

A protein is made up of amino acids.
I would select B or C as the answer because i have no idea what the other ones are :)
Most likely a silent mutation. Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype because the same amino acid is produced regardless of the change in the nucleotide sequence by the mutation.
The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.
