essential elements such as nitrogen, carbon etc. are circulated within the nature. It is referred to as a biogeochemical cycle due to the biological, chemical and geological nature of each cycle. I In other words, the ways in which elements move between its various living and nonliving forms and regions within the biosphere is called a biogeochemical cycle. Biogeochemical cycles such as nitrogen& carbon cycles are important to living organisms. Nitrogen Cycle Nitrogen is an essential element
actively forage while holding their breath. Adaptations to pressure have to deal with the mechanical effects of pressure and the increased solubility of gas at depth (Costa 2007). Adaptations to breath-holding diving center around modifications in metabolism, blood flow, and an increased oxygen storage capacity (2007). Effects of Pressure As sperm whales dive, they must deal with the direct effect of pressure that is associated with the volume change of air-filled spaces in their bodies. Changes in
plant’s life cycle, the element must not be replaceable by another element in whole, and finally the element must be direction involved in the metabolism of the plant. Chemical compounds that are involved in proper nutrition have been designated as nutrients, and further classified as macronutrients and micronutrients. Macronutrients are needed for growth, metabolism, and many other functions, but are designated as “macro” because they are required in larger amounts. Macronutrients include carbohydrates
of a catalyst, a reaction occurs which converts the ammonia to nitric oxide. The nitric oxide is further reacted in the presence of water to produce nitric acid. Nitric acid and ammonia are used to make ammonium nitrate. Its high concentration of nitrogen makes this material a good fertilizer component. Finally, it can then be stored until it is ready to be granulated and blended with the other fertilizer components. Phosphorous fertilizer component Phosphorus is treated with sulfuric acid to isolate
sun's energy for photosynthesis, and water, but they have to take all their nutrition to grow and reproduce from the water. I am going to look at how lemna are affected by deficiencies in nitrogen, iron and magnesium. Question How do lemna plants cope in environments lacking certain mineral salts - nitrogen, iron and magnesium?

Molybdenum is used in synthesis of ascorbic acid and making the iron available in plant. It also helps Phosphorus metabolism and limits ethane to ethylene in plants. Molybdenum serves as an antidote to plants to have excess in Calcium, Manganese, Zinc, and Boron in plants. Deficiency in molybdenum will shows yellowing and stunting growth of plants. 2.1.18 Zinc in Soil
pellets or powder, urea is widely used in the agricultural industry as fertilizers. This is due to the high nitrogen content of urea where it has around 46.67% as compared to other nitrogenous fertilizer where ammonium nitrate contains only 35.00% and ammonium sulphate 21.21%. This makes urea the highest amount of nitrogen per mass total among the three and is the lowest cost per pound nitrogen. (D.W. James, 2010) Scientifically known as carbonyldiamide or carbonyldiamine, it is a nitrogenous organic
crop. Sixteen important nutrients are vital for plant growth. These are 1. Macronutrients: These nutrients are required in higher amounts for plant growth. a. Primary macronutrients: Primary macronutrients are the major macronutrients and these are Nitrogen (N), Phosphorus (P) and Potassium (K). b. Secondary macronutrients: Secondary macronutrients are Calcium, Magnesium,
primary, secondary, or tertiary phosphate. Also known as trisodium phosphate, tertiary sodium phosphate is used as a detergent and water softener. Primary and secondary phosphates contain hydrogen and are acid salts. Phosphates are important to metabolism in both plants and animals.

The Physicochemical properties of the soil especially pH, organic carbon, nitrogen, phosphorus and available potassium influence the population dynamics and colonization of VAM Mycorrhiza in mustard crops (Arpita et al.,
Introduction: Wetland soils are widely diverse. They are found from the arctic to the tropics. They can be mineral or organic, seasonal or year-round, marine or freshwater. The one thing they all have in common is that, for at least part of the year, they are saturated with water. This saturation has a significant impact on the soil's characteristics such as the biota, chemistry, and physics. However, over the past century more than half of all the wetlands in the United States have been drained
Antoine Laurent Lavoisier is considered to be the father of modern-day chemistry. He had an unbelievable impact on the way the world views chemistry today. From identifying elements to discovering the importance of the role of combustion, he played an essential part in the world’s scientific ideas and inventions. He was so influential that he is said to have an equal if not greater impact in chemistry as Newton did in physics. Because of these accomplishments, he is considered one of France’s and
to planetesimal collisions releasing gases present in the Earth, after the initial atmosphere of Hydrogen and Helium escaped Earth’s gravity assisted by heat energy. The earlier atmosphere is believed to have consisted mainly of carbon, hydrogen, nitrogen, and oxygen (bonded to other elements) in such forms as CO2/CO, N2, and H20. Stanley Miller, through experimentation, shows that given an energy source like heat or electric charge it is possible to form reactions that create complex molecules

Week 7 Assignment 1—Metabolism Ketosis develops in the postabsorptive state. What is ketosis? Why does it develop? What metabolic effects does it have? Ketosis means our bodies are using fat for energy. Ketones (also called ketone bodies) are molecules generated during fat metabolism. Most of the fats our bodies break down for energy is converted into ATP, which is the “energy molecule.” Ketones are produced as part of the process. When people eat fewer carbohydrates, more ketones are generated
The Effect of pH on the Activity of Catalase Planning Experimental Work Secondary Resources Catalase is a type of enzyme found in different types of foods such as potatoes, apples and livers. It speeds up the disintegration of hydrogen peroxide into water because of the molecule of hydrogen peroxide (H2O2) but it remains unchanged at the end of the reaction. This is a type of reaction where a molecule is broken down into smaller pieces. It is called an anabolic
magnesium preventing corrosion in air. Rain is naturally acidic, due to the CO2 dissolved in it, however when sulphur dioxide and oxides of nitrogen react with the rain water they form sulphuric, and nitric acids which make the rain strongly acidic. SO2 + ½O2 + H2O → H2SO4 It may also take the form of snow or fog. The sulphur dioxides and oxides of nitrogen come mainly from industry. Acid rain is currently a subject of great controversy because of widespread environmental damage for which
7 pounds of air for each pound of gas, the mixture is rich. The exhaust from the combustion in a cars engine is comprised of six main ingredients. Nitrogen gas, carbon dioxide, and water vapor are three of the main emissions. These gases do not cause damage to the atmosphere like the other gases do. Carbon Monoxide, other hydrocarbons, and Nitrogen Oxides result in a majority of the pollution caused by cars. Carbon Monoxide is a colorless and odorless gas that can kill you if too much is inhaled

Nitrogen management is crucial component for sustainable crop production, it is desirable to adapt N supply with crop N use to maximize efficiency. In Egypt, due to intensive cultivation of high yielding crop varieties, the nutrients supplying capacity of soil is declining. Producers tend to apply insurance application of N to make them feel more confident about N sufficiency. These practices may lead to over application of N fertilizer and result in groundwater pollution by nitrate (NO3) due to
