Investigation the effect of the organic solvents on the cell membrane of the beetroot Objective: To investigate the effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to

By his mid-20s Alberto Villoldo was the youngest clinical professor at San Francisco State University. He was directing his own laboratory‚ the Biological Self-Regulation Lab‚ investigating how energy medicine and visualization could change the chemistry of the brain. One day in his laboratory‚ Alberto realized that his research had to get bigger instead of smaller‚ that he was looking out of the wrong end of the microscope. He needed to find a system larger than the neural networks of the brain
