The impact on the Phosphorus cycle is probably the slowest cycle but we a pumping out high amount which the environment is not able to recover from as it normally would. “This is a slow process is the normal of replenishing phosphorus that is lost because of runoff and leaching”(Wright‚ 2011). This cycle is important for the growth of many plants. This cycle is being damaged

investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of change in momentum and kinetic energy that occurred in elastic collisions‚ it

transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters (d = 2 m)‚ then it does the work W = (10 N)(2 m) = 20 N m = 20 J. This is approximately

hormone rather than a decrease in production of the substance. Causes- The parathyroid glands help to use‚ monitor and remove calcium from the body. This occurs thanks to the production of parathyroid hormone‚ or PTH. PTH helps control the calcium‚ phosphorus and vitamin D levels in the blood and bones. People with the Pseudohypoparathyroidism produce the right amount of PTH‚ but the body is "resistant" to its effect. This causes calcium levels in the blood are low and those of high phosphate. The Pseudohypoparathyroidism

creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater should be no more than 1.3-2.2 milligrams per liter and the phosphorus levels should also be low. It is not good to have low levels of dissolved
