shows that Pierre de Fermat (1601-1665)‚ also a French mathematician and scholar‚ did more to develop the Cartesian system than did Descartes. The development of the Cartesian coordinate system enabled the development of perspective and projective geometry. It would later play an intrinsic role in the development of calculus by Isaac Newton andGottfried Wilhelm Leibniz.[3] Nicole Oresme‚ a French philosopher of the 14th Century‚ used constructions similar to Cartesian coordinates well before the time

the study and understanding of whole organisms. Biochemistry is closely related to molecular biology‚ the study of the molecular mechanisms by which genetic information encoded in DNA is able to result in the processes of life. Depending on the exact definition of the terms used‚ molecular biology can be thought of as a branch of biochemistry‚ or biochemistry as a tool with which to investigate and study molecular biology. Much of biochemistry deals with the structures‚ functions and interactions

subjects such as Plant Biotechnology‚ Animal Biotechnology‚ Biopharmaceuticals. I have deep interest towards molecular biology. The basic unit of life is the cell and the events associated with it is the molecular biology which when disturbed due to any reason causes problem in the form of disease‚ so whether a person lives normally or suffers from a disease it’s all depends upon the molecular biological state of his constituent cells.

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

X – 4L March 24‚ 2015 ABSTRACT The effect of molecular weight and time on the rate of diffusion was determined using the agar-water gel test. A petri dish of agar-water gel with three wells was prepared and a prepared solution of each substance was dropped on each well; one with potassium permanganate (KMnO4)‚
