A pure substance is any substance on its own. For example, sand is impure for containing lots of different substances. However, diamonds are mostly pure for only containing one type of substance.
Whether a substance is pure or not doesn't relate to a substance's molecular structure, but different molecules in a substance. Water by itself is only H2O, therefore it still pure.
Water is not an element but a compound for containing different elements, however it still pure.
many advantage of genetically modified crops. such as diseases free, increase yield according to own desire, we introduce vit A in Golden rice that is useful , etc

Condensation is a process via which a liquid directly converts to a gaseous state, skipping the liquid state altogether. Therefore, a very cloudy sky is an example of water being converted to gaseous state directly.

Answer:
They became different.
Explanation:
Since the populations were separated and were not able to interact, they could not reproduce. Eventually, mutations would work their ways into each of the separate populations of squirrels. Since the two populations can't mix their genes through breeding they will slowly start to get different. For example, one population could experience a mutation that changes the color of one animals in the one of the populations. This squirrel will spread its genes to its offspring and if it is a good trait then it will spread throughout the population. The other population will not experience a widespread invasion of this trait because the two populations can't breed.
