Robert Hooke looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks.
All organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. All cells come from pre-existing cells. And Anton Van Leeuwenhoek made his version of the microscope and discovered something very odd when he looked a the gunk on his teeth.
It would be D i’m pretty sure
<span>Eutrophication (the overenrichment of aquatic ecosystems with nutrients leading to algal blooms and anoxic events) is a persistent condition of surface waters and a widespread environmental problem. Some lakes have recovered after sources of nutrients were reduced. In others, recycling of phosphorus from sediments enriched by years of high nutrient inputs causes lakes to remain Eutrophic even after external inputs of phosphorus are decreased. Slow flux of phosphorus from Overfertilized soils may be even more important for maintaining eutrophication of lakes in agricultural regions. This type of Eutrophication is not reversible unless there are substantial changes in soil management. Technologies for rapidly reducing phosphorus content of over-enriched soils, or reducing erosion rates, are needed to improve water quality.</span>
