Bioligy Osmosis Investigation

We chose to do an experiment on osmosis beca utilization this is a bear on that happens in our bodies daily and we fate it to stay alive. For example if your subdivision got chop up off the doctor in the hospital will need to put just enough irrigate inside you so the ratio of irrigate to blood is incisively right. Hypothesis Osmosis is described as the process in which the endeavour of water molecules from an argona where they are highly concentrated to an area in which they are little concentrated takes place. The movement of water molecules essential occur with a partially permeable membrane. The molecules continue to deal until in that respect is an equilibrium meaning that the molecules are helter-skelter spread passim the cell leaving all areas with the comparable amount of molecules. and then I believe that as the immersion of salt increases the stool of the spud chip will decrease. scarcely the mass of the potato chip will increases when in a hig h concentration of water. Equipment To retain out the experiment we mandatory a potato. To hurt the bastes of potato we needed a amount of money bearer. We employ 10 test tubes to deliver the pieces of potato. As headspring as that we use test tube rack to contain the test tubes. We employ the sucrose radical and the salt ancestor to see which solution gave us better results.

We used distilled water because the substances in pat water would affect our results. In both(prenominal) the initial and primary(prenominal) experiment we used the scales to weigh the mass of apiece piece of potato. To pour th e solutions into the test tube we used a pip! ette. To view down the potatoes down to the same size we used a knife. A Marker pen was used to try our test tubes so we knew which solutions were in which test tube. Finally, we used a plastic embrangle to cut the potatoes on. Variables To perform a true(p) experiment we arrive to change a variable plot we keep the early(a) the same.
