Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become

maintaining the fertility of semi-aquatic environments. 5. What geochemical cycle does not involve a stage where the chemical enters the atmosphere? In the phosphorus cycle‚ phosphorus does not enter the atmosphere unlike carbon‚ oxygen‚ and nitrogen. It remains mostly on land in rock and soil minerals‚ and in ocean sediments. There‚ phosphorus exists in the form of inorganic phosphate and is released as the rocks and sediments gradually wear down. 6. The

measure the change in kinetic and potential energies as a ball moves in free fall. Since there is no frictional forces working on the ball the total energy will remain constant and the students will see how the total energy of the ball changes during free fall. HYPOTHESIS: 1. The ball has potential energy while momentarily at rest at the top of the path. 2. The ball contains kinetic energy while in motion near the bottom of its path. 3. Kinetic energy VS.

Radioactive Isotopes An isotope is one of two or more atoms with the same number of protons‚ and position in the periodic table‚ but different number of neutrons and physical properties. Isotopes have an unstable nucleus that decay suddenly by a release of nuclear electrons and radiation. This essay will be discussing one of the applications and uses of the radioactive isotopes‚ and it will also state one problem that radioactive isotopes can address. The radiation characteristically

GPE to Kinetic energy. The car is at the peak. The energy transfers from Kinetic energy to GPE. The car starts to go down. The energy transfers again from GPE to Kinetic energy. There is no kinetic energy when the car is still at the bottom‚ as the energy has converted to GPE. The higher the lift‚ the more potential energy gained by the car. Not all the energy is converted or transferred as GPE and kinetic energy. Some of the energy is transferred as thermal energy and sound energy. Kinetic energy

The crumple zone is a structural feature in which can be mostly found in automobiles. They are constructed to absorb the kinetic energy from impact during an accident by controlled deformation. In order to absorb the impact of a head on collision‚ most of the time crumple zones are designed to be in the front part of a vehicle‚ they can also be found on the rear and sides of vehicles. Isaac Newton’s first law states that an object in motion will stay in motion with the same speed and direction unless

Another form of nutritional rickets is seen in extremely premature babies if they are fed a vitamin D poor formula or if their diet contains inadequate amounts of phosphorus and calcium. Rickets also can occur because of inherited genetic disorders that result in improper absorption or utilization of vitamin D‚ calcium‚ or phosphorus. Children with rickets may not have any symptoms‚ or they may feel pain and develop bone deformities. A child who has or is developing rickets may experience muscle
