There are four major factors that often contribute to the formation of hydrothermal copper porphyry: 1) readily available mineralizing fluid solutions that dissolve and transport metals‚ 2) openings in rocks which allow permeable flow of hydrothermal fluids and the metals that they transport in solution‚ 3) available sites within the fractured rocks which allow for deposition of the minerals from solution‚ and 4) the requisite chemical reactions that contribute to that deposition (Bateman‚ 1967)

Glycolysis‚ the Krebs cycle (or citric acid cycle) and the Electron Transport Chain (ETC) are the three phases of cellular respiration used to completely catabolise glucose. a) Glycolysis occurs in the cytosol (or cytoplasm)‚ the Krebs cycle occurs within the Mitochondria (or mitochondrial matrix) and the Electron Transport Chain occurs on the Inner Mitochondrial Membrane (Cristae- fold). b) Anaerobic respiration occurs when low amounts of oxygen (02) are present‚ releasing low amounts of energy

The Iceman was discovered on the 19th September 1991 by a German couple‚ Helmut and Erika Simons‚ who were hiking near the Austrian and Italian border in the Alps. They both had wandered slightly off trail when Erika spotted a head and shoulders sticking out of the ice‚ she first thought it was a discarded doll‚ but it was later found out to be an ancient traveler now known as the Iceman. The Iceman was quickly named Otzi‚ after the valley Otzhal that was north of his death site. At one glance‚ there

Rocks containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing

Never go by the appearance of any thing‚ be it a person or a thing. Simply wanting for it just by the looks of it can lead to great disaster. Most of the time‚ what we see is not the reality; the outside appearance generally hides all the truth and reality. Though we might say face is the index of the heart‚ there are so many methods to hide the face reactions. But that can be found out on constant and vigilant observation alone. The credit worthiness of so many things are definitely questionable
