Formed by erosion created by seafloor spreading
RIVER DELTAS ARE formed by erosion created by seafloor spreading
NOT:
caused by the movement of tectonic plates areas of infertile, rocky soil
In protista kingdom the organisms are represented in cartoon classified
If they find them unattractive there's a probability they wouldn't mate because they are different species and genera
Let's just say that everyvyear, many people either get the vaccination, or the flu. These people are left immune to the strain of flu that they were vaccinated/infected with so the number of people who can get and pass on that form of flu (think of these people as that flu strain's "habitat") is reduced. If some of that flu mutates sufficiently that the immune systems of those previously infected vaccinated people no longer recognize it, then it's habitat is expanded back to the original size again.
Hope this helped :)
Have a great day
