<span>Valles Marineris is the deepest depression found on the surface of Mars till now. I extends over 4000 km along the equator of Mars. Most scientists and researcher give there hypothesis for the formation of this depression as the erosion due to water or thermokarst.</span>
Answer:
There are 13 main parts of an animal cell: cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles.
<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>
