Blood urea nitrogen

This test is performed on organisms to see if it has the enzymes to reduce the Nitrate to Nitrite. To run the test, it will require using two colorless chemicals (so make sure you are paying attention) that will either change the color of the organism by the interaction of the new chemicals with the enzymes found in the unknown organism. So, if the organism has the capability to reduce the nitrate to nitrite the solution in the test tube will turn red almost immediately and the organism is…

Nitrogen Script Shea: The indicator we chose for this project was Nitrogen. Anjuna: Nitrogen is a chemical found in fertilizers, air pollution, factories, homes, and septic tanks. It dissolves in the run off and becomes part of the Chesapeake Bay. Then it feeds algae, which blocks sunlight from plants and animals then during decomposition, creates dead zones that steal the oxygen from the plants and animals. It kills the animals and plants which disturbs the ecosystem. If more dead zones…

His company assigned Plunkett to research and work on synthesizing various new forms of refrigerants, like ammonia and sulfur dioxide. Ammonia (NH3) is one of the most commonly produced industrial chemicals in the United States. It is used in industry and commerce, and also exists naturally in humans and in the environment. The problem is that during that time ammonia was used in most refrigerators, and it was toxic and many food-industry workers died. His team worked very hard and researched…

Savannah at High Park 1. The upper ravine slope of High Park’s oak savannahs consist primarily of black and white oak, shrubs, wildflowers, and grasses. These ecosystems also have very dry and sandy soil, which has caused the oaks to adapt to low soil nitrogen availability levels. Furthermore, the plants found in these savannahs are dependent on frequent fires to clear out the invasive species so they do not have to compete for light and also to sustain their open canopies. This causes less…

This nutrient has also been shown to improve blood vessel function. Erectile Dysfunction (ED) Some studies have indicated that L-arginine may benefit men with erectile dysfunction. In a 1999 study published in the journal BJU International, for instance, 50 men with ED were given either 5 grams of…

This datasheet provided information on common slugs. It went into short detail about slugs’ dietary needs and how this can be damaging to plants kept in the yard. It also discussed slugs’ basic activity patterns and how they are drawn out at night and occasionally on rainy days. The main purpose of this sheet, however, was to provide information on how to maintain slug populations in your yard. The methods described included the elimination of shelter, using fermented materials as bait in a trap…

A vital resource for agriculture is soil. Though a simple word, it is a complex system which provides sustainable resources to the Earth. Soil provides organic matter necessary for plant growth which supports crops and livestock. 2 It consists of disintegrated rock, organic matter, water, gases, nutrients, and microorganisms, plus it is a renewable resource (Withgott & Laposata, 2014). However, if healthy soil is not maintained, it can have devastating effects on crops and livestock. One such…

Combustion happens when a fuel reacts with oxygen. Depending on how much oxygen is available, fuels can combust completely or incompletely. Complete combustion happens when there is excess oxygen available to the fuel. Complete combustion of hydrocarbons produces water (H2O) and carbon dioxide (CO2). Incomplete combustion happens when there is limited oxygen. The incomplete combustion of hydrocarbons produces water (H2O), small amounts of Carbon Dioxide (CO2), Carbon Monoxide (CO) and…

are useful in promoting growth. Fertilizers exist naturally in the form of organic amendments, which deliver such essential nutrients as Phosphorus, Nitrogen, Potassium, and a few other macro/micro nutrients like iron, calcium, and magnesium. Nutrients also exist as a raw element, as in chemical fertilizers. Synthetic fertilizer delivers the nitrogen, but not all of it is absorbed, leading to runoff, which can cause contamination of drinking water, and algal blooms. Furthermore, chemical…

Introduction: Once a plant begins growth, it depends on multiple abiotic factors to continue growing: light, carbon dioxide and water. These three factors affect the growth rate of a plant, causing it to grow quicker or slower. Furthermore, altering these factors may stunt plants growth or improve it. For example, plants require an adequate amount of water to survive. Water hydrates the plant and also breaks down the minerals in the soil. As the plant absorbs the water, nutrients are transported…
