Thin Film is first generated in the 20th Century. With the rapid development of resource and advance scientific knowledge on preparation‚ structure evolution and the properties of thin film‚ more advance and sophisticated thin film are created by preparation devices and method based on advances in vacuum technology[1]. Thin Film is a second generation of solar cells after silicon solar cells. This smart material reacts to temperature variations‚ electricity or magnetic fields or pressure variation

ORGANIC AND INORGANIC CONSTITUENT IN ESSENTIAL IN PLANTS AND NUTRIENTS REQUIRED TO PLANTS Organic constituent DEFINITION An organ‚ system‚ or other discrete element of an organism the part of the plant that carries out photosynthesis. EXPLANATION: The chemical compounds of living things are known as organic compounds because of their association with organisms. Organic compounds‚ which are the compounds associated with life processes‚ are the subject matter of organic chemistry. Among the numerous

when a body of water enriched with excess nutrients‚ nitrogen and phosphorus from dead plant material and waste. Nitrogen pollution largely derived from agricultural fertilizers and emissions from the combustion of fossil fuels. Phosphorus pollution comes from wastewater treatment and detergents. These elements and compounds make their way to coastal areas through the drainage networks of rivers and streams. This nutrient and phosphorus mix results in increased algae growth that makes water cloudy and

nitrogen‚ phosphorus and potassium and are represented on the outside of the bag in that order. Each of the three elements has a different benefit to the growth of a plant. Plants use nitrogen to digest proteins‚ nucleic acids and hormones. When a plant is lacking in nitrogen‚ it may have stunted growth and yellowing leaves. Phosphorus is also very important to plant growth. It assists in converting the sun’s energy and other chemicals into usable foot for the plant. A lack of phosphorus can also

A centrifuge was used next in order to separate the bacterium from the phages and protein. After completion‚ the radiation concentrations of E. coli and the protein shells were measured. The results showed that there were large quantities of the phosphorus tracer only in the bacterial sample‚ demonstrating that DNA was transferred from the bacteriophage to the host organism. Further to this‚ despite the protein shells being detached while phage reproduction‚ the virus was copied in each of the host

There are 92 naturally occurring elements‚ only 17 of them make up 99.5% of the earth’s crust (including oceans and atmosphere). - In living things (plants‚ animals‚ people) the six most abundant elements are carbon‚ hydrogen‚ oxygen‚ nitrogen‚ phosphorus and sulfur. - The universe is dominated by the elements hydrogen (83%) and helium (16%) 1. The Crust The outside of the earth is a thin crust which is approximately 20 to 40km thick. The crust is a formation of dips and hollows which are

On the other hand‚ the main difference between a chemical fertilizer and an organic fertilizer is that the chemical fertilizer comes out of a lab and the organic fertilizer comes from living beings. A chemical fertilizer is synthetically prepared to include the vital nutrients that are necessary for the plant growth process. All chemical fertilizers contain the normal NPK (nitrogen‚ phosphorus‚ and potassium) requirement and any other
