functioning) or be so compressed that they become greatly damaged (Medline plus, 2016). If we have too little water in our bodies, the blood will beome hypertonic to the environment in surrounding cells, causing water to leave cells and enter the blood by osmosis, this makes cells shrivel and potential die or become unable to carry out their functions. As cells become dehydrated they increase their coating of cholestrol which is designed to help the cell retain water. However if dehydration is…

In the homeostasis, osmosis, and diffusion carrot lab, the mean growth in weight for the carrots soaked in solution A, one of our blue solutions, was 0.151 grams. Solution A had a standard deviation of 0.048. For solution B carrots, one of our clear solutions, the mean growth was 0.117 grams. Solution B had a standard deviation of 0.057. For solution C carrots, our other blue solution, the mean growth was negative, actually indicating a loss in weight. This mean loss was -1.426 grams. Solution C…

dissolved sugar. Although the sugar molecules were too large to pass through the semipermeable membrane of the egg, water molecules were able to exit the egg. After twenty-four hours, the egg had decreased from a mass of 84.1 grams to 47.0 grams due to osmosis. The corn syrup is hypertonic in comparison to the egg and thus the water moved from a high concentration of water in the egg to a lower concentration of water in the syrup in order to reach equilibrium. Subsequently, the corn syrup was…

Reservoir Systems consist of a hollow inner core and a polymer membrane, there to control the rate of drug diffusion. Drug diffusion across the membrane is rate limited and controls general drug release rate (Bajpai et al. 2008). For reservoir systems drug release normally remains steady resulting in a zero order profile (Raval, Parikh and Engineer, 2010). Another technology is called the Multiparticulate drug delivery system which consists of microencapsulated granules/beads containing drug…

cell. Adding ethanol disrupts much of this. 1. Ethanol is permeable to cell membranes. Because of the nature of ethanol as a chemical is it able to get into the cell very easily. This disrupts the balance of the cells' osmotic environment. Osmosis is the movement of water. Think about what happens if you fill a balloon too full. What happens? It expands and stretches the membrane of the balloon. If you release too much water from the balloon it crumples the membrane…

Cells use various methods of transportation to move material in and out of the cell. The semi-permeable plasma membrane surrounds the cell and allows certain materials to enter and exit the cell. Simple diffusion is movement of molecule through the plasma membrane without the help of any channel or proteins. In simple diffusion molecule move down their concentration gradient; as a result, they don’t require energy input. In the computer simulated lab for simple diffusion, nothing will move…

Hypothesis 2: The number of carrier proteins will increase if the glucose diffusion rate increases, only if number of carrier proteins correlates to facilitated diffusion. Hypothesis 3: The rate of osmosis for the solutions increases, if there is an increase in the MWCO’s and pressure for different solutes. Hypothesis 4: If the MWCO’s increase the pore size, the rate of filtration will increase, but if there is an increase in filtration residue, there…

The water inside the cell is hypotonic because it has less of the solute (alcohol). The solution in the cell's environment has a higher concentration than the inside of the cell which means that is hypertonic. This means that diffusion of water (osmosis) will occur. The water inside the cell would diffuse to the outside of the cell when there is a higher concentration of alcohol because there is a lower concentration of water outside the cell. The water would diffuse because water diffuses…

dialysis Cell B was placed in 5% glucose and 95% water solution, therefore making the concentration of water inside the cell (100% water), greater than the concentration of water outside the cell (95% water). This data has proved the concept of osmosis in the cells, related to our claim that water molecules move out of the cell because the concentration of water is greater inside therefore cell than it is outside the cell. The cells have to maintain a balance so that the concentration of water…

solution, which is the outside of the Solanum tuberosum core. Thus, the Solanum tuberosum core will decrease in mass due to the fact that plasmolysis will occur, which will cause the Solanum tuberosum core to shrink in size by the loss of water through osmosis. The greater the concentration of solute the higher the osmolarity. Therefore, the osmolarity of Solanum tuberosum core cannot occur at 0.8 M (±0.01 g), as it is the greatest concentration, thus, the osmolarity is higher, and the Solanum…
