1 DESIGN 1.1 Defining the problem Focus / Research question How does osmosis work and what effect will this have on the raisin at different sucrose concentrations? Hypothesis The raisin in the beaker with most diluted sucrose solution will gain the most mass‚ therefore the control (0% sucrose solution) should be the most successful (in relation to the aim.) Background Information / theory Osmosis may occur when there is a partially permeable membrane‚ such as a cell membrane

Executive Summary The recent acquisition of French energy company Alstom by General Electric has made a lot of headlines in the world recently. This is one of the largest acquisitions by the General Electric and involved a lot of complexities. The Alstom’s board of directors was ready to cut the deal with General Electric but French government has made this deal as the national pride and tried to interfere. They opposed this deal on the ground of loss of jobs in France but in reality the French

Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured

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 to a low concentration‚ so in this case water would move from the
