An eco-column is used to model an ecosystem on a smaller scale. The purpose of an eco-column is to examine how an actual ecosystem would respond to different conditions. Eco-columns typically have three chambers: the aquatic chamber‚ decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples

his story on the Trajan’s Column‚ and to have the effect he wished to convey. The sculptor wanted to tell the story of the emperor Trajan to the people of Rome and illustrate his victories and achievement by the carvings on the column. He uses the technique “continuous narration” to let the story unfold within the spirals without any interruption. This progression of events is not always consecutive and is sometimes simultaneous. Due to the increasing distance of the column from the ground‚ the sculptor

Chromatography of Commercial Analgesics Using the thin layer chromatography the major components of a commercial analgesic tablet will be indentified and purified. The active ingredients of the analgesic used were characterized by comparison with chromatograms of aspirin‚ acetaminophen‚ ibuprofen‚ mefanemic acid‚ and caffeine through the use of UV chromatography then the Rf value was calculated for each solvent. INTRODUCTION In this experiment‚ thin-layer chromatography (TLC) will be used

Chromatography of Photosynthetic Pigments Abstract In this experiment a process of chromatography was used to separate chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta carotene. When these pigments were obtained they were used to measure the wavelengths by way of spectrophotometer of each and the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how

Conclusion 1.2.2 Ashwath Ramesh 1. Why are there sutures on the human skull? What does this tell you about the actual structure of the skull? There are sutures on the skull because when you were born the skull was six parts and that allow the head to come out of the birth canal‚ then it will mend together into 3 parts. 2. Think about the structure and function of your backbone. Why do you think there are discs of cartilage between the bones in the vertebral column? There are

Chromatography is the separation of compounds to allow us to see the different colours of that compound‚ for instance we may use chromatography in a school lab to see the real colour compounds of plants and grass‚ by using chemicals such as acetone we it will allow the object to break compounds and thus we can see the true colour of the grass. In today’s society there are many real world applications which use the chromatography technique in their line of work‚ an example of one of these applications

Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as
