For the last few decades, cloning was a fictitious idea that lay deep within the pages of some sci-fi novels. The very idea that cloning could one day become reality was thought to be a scientific impossibility by many experts but on one exhilarating day, what was thought to be "purely fiction" became reality. That fine day was February 22, 1997. A team from the Roslin Institute which was lead...

Biology essays / Gibb's Free Energy Cycle
The second law of thermodynamics states that energy transitions are imperfect. No matter what, energy is lost. In machines an 75% loss of energy is considered average. In biological reactions there is usually a 60% loss. Since all reactions are constantly losing a percentage of the energy they give, it is necessary to have a constant intake of energy to make up for what is lost. This intake o...
