Permeable Membrane Semi Permeable
856 wordsStudying the Effect of Various Glucose Concentrations on Osmosis in a Potato Osmosis is the process in which water particles move from an area of high water concentration to an area of low water concentration through a semi-permeable membrane until the concentrations are equal. Osmosis has the same basic theory as diffusion. Particles are moving from an area where they are in great concentration to an area where they are in low concentration until the concentrations are the same. Osmosis is this...

Da Vinci Operating Room
832 wordsJust as computers revolutionized the later half of the twentieth century, the field of robotics has the promise to equally alter the way we live in the twenty first century. We have already seen how robots have modified the manufacturing of cars and other customer goods by streamlining and speeding up the assembly lines. Robots have also enabled us to see places that humans are not yet able to visit, such as other planets and depths of the ocean never before explored. And just as computer contro...

Rate Of Reaction Amount Of Water
1,531 wordsPhotosynthesis is a very important process in nature. It is the production of energy in the form of glucose involving water from the soil, carbon dioxide from the air and light energy. It takes place in all green plants, which use the green chlorophyll, held in chloroplasts in the leaves, to trap light. The main site of photosynthesis is the palisade mesophyll cells in the leaf of a plant. It is these cells that contain the green chloroplasts and are very well adapted to their task. They are nea...
