aquaculture‚ raising aquatic animals such as snails‚ fish‚ crayfish or prawns in tanks‚ with hydroponics cultivating plants in water in a symbiotic environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria into nitrates and nitrites‚ which are utilized by the plants as nutrients.

requirement for producers – the first organisms in any food chain‚ and at times a dangerous waste product. Where plants use carbon dioxide during the Calvin cycle of photosynthesis‚ at night they also produce small quantities due to respiration. Fundamentally‚ carbon dioxide reacts with ribulose bisphosphate to produce glycerate 3-phosphate in the light independent reaction. In turn glycerate3-phosphate is reduced to triose phosphate using reduced NADP and ATP from the light dependent reaction

The Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first

Oxygen Requirements of Bacteria BACKGROUND The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms. A candle jar is useful

Executive Summary The purpose of this report is to critically analyse the need for effective management of absence in the workplace. In order to do this I examined the reports and statistics concerning absence in recent years. I also looked at our own absence management policies and procedures. My initial finding was that there is no written policy for dealing with absence. From my research I would recommend that a written policy should be devised and implemented. This policy should

physics‚ energy is an indirectly observed quantity which comes in many forms‚ such as kinetic energy‚ potential energy‚ radiant energy‚ and many others; which are listed in this summary article. This is a major topic in science and technology and this article gives an overview of its major aspects‚ and provides links to the many specific articles about energy in its different forms and contexts. The question "what is energy?" is difficult to answer in a simple‚ intuitive way‚ although energy can be rigorously

Why Is Cameron? why not How do you produce nuclear energy? In a nuclear-fueled power plant – much like a fossil-fueled power plant – water is turned into steam‚ which in turn drives turbine generators to produce electricity. The difference is the source of heat. At nuclear power plants‚ the heat to make the steam is created when uranium atoms split – called fission. What is the process that occurs during a nuclear chain reaction? Nuclear Chain Reactions. A chain reaction refers to a process in
