Let's say a geographical barrier separates a species into two different population. Which also cause a reproductive isolation ( the two pupolations cannot interbred)
Throughout the time (lets say a million years), the two populations will undergo a lot of changes in their respective genomes and eventually will form 2 different species.
If there is no reproductive isolation, the 2 population could interbred with one another and there will be no speciation

Answer:
when the pores are completely filled in the rocks and soil
Explanation:
The zone of saturation is part of the divisions of ground water systems. It is the zone in which the pore spaces within the rock are completely filled with water.
The zone of saturation is where the aquifer lies in a body of water and it is the ground water prospect. Pore spaces can also be filled with hydrocarbons.
Above the zone of saturation is the water table. The water table defines the upper layer of the zone of saturation above which the pore spaces are filled with gas or no water can be found.
the only reason i am wasting one of the two answers your post is allowed to get is because its been 3 hours and no one has answered yet.
Where do you go to school? I think it is very coincidental that you have the exact same question i do, and you had the question exactly when I got the question...about 3 hours ago. Now it IS a curriculum so its not that weird, but by any chance are you in K12? 8th grade?
