Phosphorus

and duckweed solution, there will be more fronds of duckweed because the phosphorus and nitrogen in the dish soap will cause eutrophication and increased growth in the duckweed. There was not a significant (20%or more) difference in growth in any of the jars. The expected results were that jar B would have the most growth of duckweed because it was the most concentrated with dish soap, so there was more nitrogen and phosphorus in the jar to cause eutrophication. The expected result was that with…

Cunha, Bottino and Calijuri (2010), examined how land use patterns within the Ribeira do Iguape watershed, Sao Paulo, Brazil, with varied levels of anthropogenic interference influenced eutrophication variables (total suspended solids (TSS), total phosphorus (TP), chlorophyll-a (Chl-a) and total nitrogen (TN)) ranges in three rivers (Canha, Pariquera-Acu and Jacupiranguinha Rivers). Eutrophication is one of the major problems affecting freshwater ecosystems because it restricts water usage,…

When bones and muscles connect a joint is formed. At this point both are joined together by the help of tendons, which is a connective tissue. When we have to move a joint the muscle receives an electrical signal from brain. It causes movement to occur, because this causes the contraction in it. This contraction pulls on the corresponding bone at its insertion point. Stationary bone is called the point of origin for the skeletal muscle, while the one which moves is known as the point of…

zinc, copper, molybdenum, and nickel. (3). Fertilizer enhances the growth rate of plants. Fertilizer adds nutrients and modifies the water retention and aeration of plants. Fertilizer contains three main macronutrients: nitrogen for leaf growth; phosphorus for the development of roots, flowers, seeds, and fruits; and potassium for strong stem growth. While also containing all the necessary micronutrients needed by plants except for chlorine and nickel. (2). Different types of fertilizer will…

Having lost numerous solders to the dreaded Russian winters, the High Nazi party commanded the study behind frostbite and hypothermia. In these, the experiments were designed to simulate the conditions to which the German soldiers had to face when fighting the Russian enemy at the eastern front. The experiments were conducted under the supervision of Dr. Sigmund Rascher at Birkenau concentration camp, Dachau and Aushcwitz. Dr. Rascher reported their results directly to Himmler, Commander in…

calcium, phosphorus, zinc and other minerals along with certain valuable vitamins such as folate, vitamin E in alpha tocopherol form, iron, magnesium and more depending on the seeds that you select to consume. You should mix the seeds for this reason to ensure you receive the wide assortment of nutrients that they will provide to your body. Vitamin E is a powerful antioxidant that boosts the immune system, and zinc helps the body heal. Calcium helps to build strong bones and phosphorus is…

nutrient to keep our bone healthy. According to my food list, the foods that contain high calcium were yogurt, bok choy, and tofu. However, I still need to consume more food like these. On the other hand, my phosphorus intake was 949.67 mg, so it was over higher than the recommended amount of phosphorus intake, which just was 700.00 mg. Furthermore, too much phosphate can be toxic. An excess of the mineral can cause diarrhea, as well as a hardening of organs and soft tissue. Also, it will…

Studies have shown that excessive phosphorus intake can put one at risk for osteoporosis and heart disease. Calcium and phosphorus work together to help build and maintain healthy teeth. An overdose of phosphoric acid can throw off the balance of the two, which can lead to the decay of teeth. An overabundance of phosphoric acid decreases…

Synthesis of reactive iron Chemical reduction method of Ferric chloride by sodium borohydride following reaction (Eq.1), was used to synthesize ZVI [14]. 〖2FeCl〗_3+〖6NaBH〗_4+〖18H〗_2 O→〖2Fe〗^0+〖21H〗_2+〖6B(OH)〗_3+6NaCl (1) Ferric chloride hexahydrate solution was prepared by dissolving 5 g of FeCl_3.H_2 O (99.0%, Junsei Chemical Co., Japan) in 125 mL of deoxygenated deionized (DI) water. Moreover, 3.5 g of Sodium borohydride (NaBH_4, 98.0%, Sigma–Aldrich Inc., USA) were dissolved in 125 mL…
