Cloning also brings up many ethical points dealing with creation and psychological well being of clones. Cloning is such a new area of study that it requires a large amount o...
In research facilities all around the world scientist are attempting to stop diseases at their very roots. Instead of trying to find drugs to cure illnesses they are trying to change the genes that cause the diseases. The process by which this is done is called gene therapy. Gene therapy is the deliberate alteration of the human genome for a...

Lab Report The structure of the earth is made up of many layers, but the crust and the upper mantle make up the lithosphere. The lithosphere is divided into individual sections called plates. The rest of the mantle makes up the asthenosphere. Convection in asthenosphere causes the plates to shift and move about....
