Nitrogen dioxide

When nitrogen is applied to the ground in the method of fertilizer to help the agriculture crops grow, it can be washed off by rain or can seep down into the groundwater. If that water is used as a source of drinking water, the excess nitrogen in that water consumed by humans can cause cancer or respiratory problems. If there is too much nitrogen in bodies of water, it can result in the eutrophication and result in too much…

Nitrogen (N) - Low ~ Answer the following questions in complete sentences. Your answers will be based on your soil test results, what you have learned in class and independent research. ~ 1. Why is nitrogen important in soil? What does nitrogen do for the soil? ~Nitrogen is so important because it is a major component of chlorophyll, which plants use to photosynthesize. It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die. Some…

1. The distribution of organisms simply means the abundance of organisms on Earth. All organisms are live in different biomes because of their characteristics of survival. Furthermore, all organisms are unique and need certain living conditions. For example, polar bears and lizards will not be able to live in similar biomes because of their characteristics and behaviors on survival. Lizards depend on the sun for energy and heat while polar bears retain heat with their fur to stay warm because…

Phosphorus is an essential nutrient to all forms of life and is required for building DNA, RNA and amino acids (Paytan, 2011). Phosphorus is often a limiting nutrient in ecosystems, along with nitrogen, and therefore its abundance determines the amount of primary production that can occur within a system (Schindler, 1971). The two main types of phosphorus are inorganic phosphate minerals, such as calcium phosphate rock that is mined for fertilizer, and organic compounds containing phosphorus…

Gunpowder is one of china’s four greatest inventions. Gunpowder is an ancient chemical explosive that was accidently created by Chinese Taoists who were attempting to create a portion of immortality by combining salt peter, sulfur, and charcoal. There are multiple types of gun powder: Black powder (organic), black powder (modern / synthetic), cordite, smokeless ball powder (aka spherical powder), smokeless flake powder (found in shot shells), and smokeless stick powder (aka extruded powder).…

The Anthropocene is an era characterized by humans’ intercontinental impact on ecological systems and processes (Steffen et al. 2011). Monitoring ecosystem function and fluctuation is the primary interest of Dr. David Lewis, who examines variables associated with the Anthropocene, including: land modification, nutrient cycling, hydrologic perturbations, and climate change. Many anthropogenic activities result in heightened nutrient inputs into the environment (Foley et al. 2005), including land…

At Pyro’s Academy, we have a lot to offer and to teach you! For example, you learn about the different types of chemical reactions such as combustion and displacement, how to write word equations about chemical reactions and the difference between exothermic reactions and endothermic reactions. To write combustion as a word equation you would write ‘___ -> Oxygen = ___ Oxide’ so if the element you were burning was Iron, the product would be Iron Oxide. In a chemical reaction, the surroundings…

The Effects of Cryotherapy on Recovery Student’s Name Institution The Effects of Cryotherapy on Recovery Introduction It was proved by modern medicine that using of cold provides healing of the human body. Local cryotherapy as cold application has become one of the directions of physiotherapy. Currently, the information concerning cryotherapy is abundantly available. Therefore, the main goal of this work is precise and direct research on the effects of cryotherapy and…

The emergence of cytochrome oxidase is considered to be a very important event in evolutionary history. However, not much is known on the development and emergence of this enzyme. Molecular data demonstrates how cytochrome oxidase emerged before the divergence of archaea and bacteria, and well before the great oxidation event. This paper proposes a research plan to investigate the origins of cytochrome oxidase. Background Throughout the three domains of life, a variety of metabolisms are present…

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…
