    show the water potentials of young‚ old and damaged potatoes and different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn‚ 2009)‚ moving water from a high

    likes. King Richard in Richard III is no different. His syntax shortens‚ his diction darkens‚ and his imagery grows worrisome. The change in Richard’s syntax‚ diction‚ and imagery pattern indicates his emotional change from open and relaxed to stressed and self-conscious. In his first soliloquy‚ Richard’s syntax flows. He speaks using iambic pentameter‚ and the structure moves on with a relaxed feeling. The lengths of his sentences also vary giving more of a natural movement. The sentence structure

    solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation will determine how different concentrated sugar water will affect

    The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the
