remarkable possibility of being able to partition proteins and other cell components between phases of nearly the same hydrophilicity. Proteins can be separated by partitioning if they have unequal distribution between the phases, i.e. when their partition coefficients, K (the concentration in top phase divided by the concentration in bottom phase), differ. Usually the difference in the K value of many proteins is not very large and then repeated extractions have to be carried out to get a reasonable

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
