Answer:
Sand
Explanation:
Soil particles between 0.1 and 2 mm are considered sand. The range to be considered sand is 0.05 to 0.2 mm.
In the case of silt, it includes particles with a diameter between 0.005 and 0.02.
On the other hand, clay has values lower than 0.002.
Finally marl, does not depend on its size, but on its composition.
Hola!
Geographic Isolation prevents the cross breeding between the populations that have been separated by the isolation.
Without the separation the two growing population would be brought closer together and members of the two populations will cross breed.
♦ Example:
There are two populations of squirrels on either side of the grand canyon.

These populations are considered two different species.
We can conclude that these 2 populations were once one population.
Isolation allowed the two populations to move apart and speciation occurred.
hope it helps!
Complementary is described as: combining in such a way as to enhance or emphasize the qualities of each other or another. So I think fitting together is sillier in the way that complementary loosely means when two things together make something better and when two puzzle pieces fit together they compliment each other by fitting together and making the bigger picture, hope this helps!
