Plants, animals, fungi, slime moulds, protozoa, and algae are all eukaryotic. 1  These cells are about fifteen times wider than a typical prokaryote and can be as much as a thousand times greater in volume.
A drought is a period of below-average precipitation in a given region, resulting in prolonged shortages in its waters supply, whether atmospheric, surface or ground water.
Certain regions within the United States are more susceptible to droughts than others. Droughts can be more damaging than tornadoes, tropical cyclones, winter storms and flooding combined. Unlike a hurricane, tornado or flooding, the onset of droughts happen gradually over a long period of time.
