Flame Tests 12.01.2010 19.01.2010 Introduction The normal electron configuration of atoms or ions of an element is known as the “ground state”. In this most stable energy state‚ all electrons are in the lowest energy levels available. When atoms or ions in the ground state are heated to high temperatures‚ some electrons may absorb enough energy to allow them to “jump” to higher energy levels. The element is then said to be in the “excited state”. This excited configuration is unstable‚

This particular experiment could be very useful to scientists as a similar procedure could help identify genetic diseases and could also aid in finding cures for those genetic diseases. Based on assumption our hypothesis was formed and it was believed that the banana would yield the most DNA after undergoing our test. We came to this assumption from the idea that the banana was denser than the other samples‚ and would

understanding of how life began. There have been many breakthroughs in biology that have helped us step forward in the central idea of where the first organisms on Earth began‚ and even though none can be fully proven‚ they will still aid in our upcoming journey of the origins of life. Using the better known hypotheses Primordial Soup‚ IronSulfur World‚ Deep Sea Vent‚ RNA World‚ Community Clay‚ and Panspermia Hypothesis‚ our world will benefit from the progress we will make from the study of these theories

The efficient-market hypothesis emphasizes that arbitrage will rapidly eliminate any profit opportunities and drive market prices back to fair value. Behavioral-finance specialists may concede that there are no easy profits‚ but argue that arbitrage is costly and sometimes slow-working‚ so that deviations from fair value may persist. Sorting out the puzzles will take time‚ but we suggest that financial managers should assume‚ at least as a starting point‚ that there are no free lunches to be

specific group or set. This process of visualizing logical relationships was devised by John Venn (1834-1923). Each Venn diagram begins with a rectangle representing the universal set. Then each set of values in the problem is represented by a circle. Any values that belong to more than one set will be placed in the sections where the circles overlap. The universal set is often the "type" of values that are solutions to the problem. For example‚ the universal set could be the set of all integers
