A stable atom with neutral charge has the same number of protons and electrons.
While the charge of protons is positve and the charge of electrons is negative, the magnitude of their charges are equal.
Then, in order to the atom be neutral the positve charge equals the negative charge, and so the number of protons equals the number of electrons.
Answer:
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.

This is the reason why its trees shed its leaves according to season.</span>
