carbohydrates. Leguminous plants and nitrogen-fixation bacteria: Nitrogen-fixing bacteria living in the root nodules of leguminous plants change the atmospheric nitrogen gas into nitrogenous compounds. Functions of leguminous plants: 1. They protect the bacteria. 2. They carry out photosynthesis to make carbohydrates. Functions of nitrogen fixation bacteria It lives inside the root cortex to divide and form swelling nodules. It converts nitrogen gas to form ammonia/nitrogenous compounds

ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated

DRY ICE Introduction The topic I have chosen to write this report on is dry ice (also known as liquid nitrogen). This topic has quite an interest to me in a sense that I am curious about the dry ice as a whole. I have seen it being used but always thought about the manufacturing behind it. I am hopeful in finding out information such as what exactly dry ice is‚ how the dry ice is made/formed‚ what it has use for‚ and who was behind the making or discovery of dry ice. Some questions that I

According to the World Bank‚ in 2007 air pollution cost about 3.8% of China’s 2. gross domestic product‚ mainly from diseases and loss of lives. 3. World Health Organization estimates that in India alone about 500‚000 premature deaths are caused each year by indoor air pollution. 4. Serious respiratory disease-related problems have been identified for both indoor and outdoor pollution in major cities of several countries. 5.

The four nitrogen bases are Adenine‚ Thymine‚ Guanine and Cytosine. 2. B. Nitrogen bases‚ and hydrogen bonds make the "ladder". C. The phosphate and deoxyribose sugar makes up the backbone of the "ladder". D. They are anti-parallel because the both sides aren’t parallel. 4. Adenine is always attached

An experiment was carried out at the Horticulture Farm‚ Bangladesh Agricultural University‚ Mymensingh during 1998-99 growing season to study the effect of nitrogen and plant spacing on the growth and yield of potato (var. Diamant). Different nitrogen levels viz. 0‚ 127.0‚ 190.5 and 254.0 kg N/ha significantly influenced plant height‚ foliage coverage‚ number of main stem per hill‚ days required for 80% maturity of the crop‚ fresh weight of haulm (g/hill)‚ number of tubers per hill‚ weight of tubers

Assess evidence‚ which indicates increases in atmospheric concentration of oxides of sulfur and nitrogen. Thorough collection of data‚ surveys‚ and tests from the 1950’s indicate a rising trend in atmospheric concentrations of oxides of sulfur and nitrogen. An enhancement in funding‚ technological and information resources‚ has led to wider and more detailed analyses of oxides of sulfur and nitrogen concentrations‚ and as the diagrams indicate (see diagrams) there is a clear rise in these oxides

One of the hydrocarbons produced is Carbon monoxide which is one of the most dangerous gases resulting in many health problems sometimes even death. Another cause of air pollution is Nitrogen oxides. Nitrogen oxide is one of the harmful gases‚ it is produced into the atmosphere by burning of fuel. Nitrogen oxide is very dangerous when combined with rain; it forms Nitrogen trioxide which is acid rain. When acidic rains pour
