Nitrogen fixation

Kishan Patel Section: 008 Pattern: Calcium levels in the soil controls soil pH and species richness within a community Hypothesis 1: Calcium levels in the soil controls soil pH. Prediction: An increase in the calcium levels in the soil will make the soil less acidic. Reasoning: Calcium exists mainly in the soil as exchangeable cations (ca^2+) associated with basic anions, which reacts with soil acidity (H) to neutralize it. Analytical approach: Regression Independent variable: Calcium levels…

Plants gain a lot of nutrients in their daily lives. They get it mostly from water and also the soil. Water is a molecule made up of the following atoms, Hydrogen and Oxygen. In this molecule the electrons are not shared equally between these atoms. Electrons are negatively charged so if they spend more time around an atom the atom becomes negative. The electrons turn Oxygen negative because they spend more time together. The reason for the electrons to be around Oxygen is because Oxygen has…

1- Nitrogen is a major component of amino acids, the building blocks of proteins. Some proteins act as structural units in plant cells, while others act as enzymes, making possible many of the biochemical reactions on which life is based. 2- Nitrogen appears in energy-transfer compounds, such as ATP (adenosine triphosphate), which allows cells to conserve and use the energy released in metabolism. 3- Nitrtate is very mobile in the soil and moves with soil water to root surfaces for plant…

problem that led to the use of this chemical was the increasing population and larger demand for food which meant farmers needed to grow higher yield crops at a faster rate. Fertilizers were heavily used to provide nutrients with ingredients such as nitrogen, phosphorus, potassium, which are essential chemical elements for plant growth and increases growth rate and photosynthesis…

had success in chemical separation technologies that minimize the formation of harmful pollutants. His work on the development of desulfurization sorbents that carry out selective adsorption of sulphur from diesel fuels and of zeolites that remove nitrogen from transportation fuels has been ground-breaking. However, there are other processes that are quite harmful to the environment such as lead ore processing. Once lead is extracted from its ore by reduction with carbon, the waste often has…

Nitrogen (N₂) is a colorless, odorless, largely inert gas with a hexagonal structure that is essential to life on earth. This nonmetal is number seven on the periodic table; in its neutral state, it has seven protons, seven neutrons, seven electrons, and an average atomic mass of 14.0067 amu. The electron configuration of this element in ground state is 2-5. Its discovery, safety, availability, and uses are important in understanding this element and its significance. Nitrogenous compounds…

previous two years have resulted in 0mg/L of nitrates occurring in the water. From a chemical standpoint, this means that the water quality is outstanding. However from a creek and biological quality standpoint, it is not healthy as plants consume nitrogen, and reproduce…

to all lakes over time as the weathering of rocks and soils from the surrounding area that leads to an accumulation of nutrients in the water. It can also be caused by run-offs of fertilisers. Three of the key components of modern fertilisers are nitrogen, phosphorous and potassium. After a rainy season these nutrients that were not absorbed, run off into waterways such as dams, lakes, rivers, streams, ponds and even sometimes swimming pools. The fertiliser triggers the growth of plants that are…

tropical regions. 2. What is unique about this fern? Why is it called ‘Azolla Superorganism’? This fern is unique because it is a little fern and has massive potential, and its called superorganism because it is symbiotic that captures all the nitrogen fertilizer it needs to grow from the air around it. In Asia, they grow it along with…

Unit 2 Project In your own words Discuss why carbon is essential to life on Earth. (150 word minimum response) Carbon is a vital element in organic compounds. Organic compounds are compounds that are usually located in living things.Organic compounds are very vital and Carbon is an elemnt that makes up organic compounds. Carbon helps organic compounds make up cells and carry out important life functions.Additionally, carbon can form strong bonds with itself and many other elements. This…
