The Upper Midwest, because of its numerous shallow lakes and marshes, rich soils, and warm summers, is described as being one of
the most important wetland regions in the world. The area is home to more than 50% of North American migratory waterfowl, with many species dependent on the potholes for breeding and feeding. In addition to supporting waterfowl hunting and birding, prairie potholes also absorb surges of rain, snow melt, and floodwaters thereby reducing the risk and severity of downstream flooding. Statewide, elevated levels of phosphorus have been found in 31% of our “prairie pothole” wetlands, negatively affecting the insects, snails, and leeches that live there. How has this elevation in phosphorous LIKELY impacted the biodiversity of the prairie potholes in Minnesota?

In my opinion, I think that coal is the most important mineral of all. It keeps us warm during winter and it helps train transport food and other goods that we need.
In a population, the sum of the relative frequencies of all alleles for a particular trait is equal to 100 percent. equal to the number of alleles for the trait
