Introduction Over the course of several weeks‚ myself and my fellow classmates have been researching and conducting an experiment that focuses on the effect of ascorbate peroxidase (a.p) as well as salt stress at different levels of concentrations on Abelmoschus esculentus (okra). Okra is a plant that is composed of 87.1% of water. In addition to being made mostly of water this highly nutritious vegetable is also composed of 0.2% of fat‚ 9.7% of carbohydrate‚ 2.2 % protein‚ 1.0 % fiber‚ and 0

The Earth is covered by 70 percent of water (Vaughn‚ par 6 ). Of that water 97% is composed of salt water‚ leaving just three percent fresh water that lies in streams‚ rivers‚ glaciers‚ and underground (Rekacewicz‚ par 1). This vast amount of water has not been yet fully discovered with only five percent being explored ( Vaughn‚ par 9). For generations the ocean has been called “The largest museum on earth” (Vaughn‚ par 8). The Earth has been maintained in a natural state of balance‚ but the advancement

This can happen in tropical lagoons with little freshwater input (salinity 35 ppt. Hypersaline lagoons Indian river lagoon‚ 42 ppt has been recorded. Neutral estuary – freshwater input- evaporation. This system is not used much anymore‚ because a single estuary could go from 1 to 3 to 2 in a year. Classification Based
