In this section a hypertonic section was visible. At the end of the vinegar solution the mass ended up as 67.9 grams after the sugar solution it resulted as 42.8 grams. The volume of the egg was also changed before the sugar solution it was 60 mL after the solution it was 45 mL. The decrease in mass and volume signals that a hypertonic solution occurred. The hypothesis made that if an egg is placed in 150 mL of syrup it would

cell may be subjected to in the cells physical environment. The cells may be isotonic‚ hypotonic‚ and hypertonic. Isotonic is when the cell and is environment have equal concentrations of solutes. Therefore cells in an isotonic solution do not experience osmosis. When the cell is hypotonic it has a lower concentration of solutes so water will move out of the cell. When the cell is hypertonic‚ it will have a higher concentration of solutes and water will move into the cell to attempt to reach

Since NaCL cannot cross the Beta vulgaris membrane‚ water will move into the Beta vulgaris membrane at a low concentration of NaCL‚ making the solution hypotonic‚ then out of the membrane as the concentration of NaCL increases‚ making the solution hypertonic.

hypotonic to the inside of the bag‚ which is hypertonic‚ the water’s net movement will flow into the bag. Also since the dialysis bag’s weight heavily depends on the amount of water‚ the mass will go up when water is gained. The class average for amount of mass gained was 22.55%. A bag that lost mass was the bag with 0% concentration‚ which means it has 100% water. The outside of the bag has 10.57% sucrose and 89.43% water. This makes the outside of the bag hypertonic to the inside‚ resulting in a net flow

This lab investigates the environmental possibilities that can damage membranes. Hypertonic and hypotonic salt solutions place stress on cell membranes‚ detergents make lipids more water-soluble and disrupt membranes‚ and acidic and basic pH’s denature proteins and change the color of the betacyanin.

The process of osmosis and its importance to living organisms Osmosis is the process by which there is a net movement of water through a semi permeable membrane from an area of high water potential to an area of low water potential. Within a cell‚ osmosis has the following effect. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell. If this is the case‚ the increase in water in the cell‚ may cause the cell to swell

duct becomes more permeable to water so more water is drawn out which means that less urine volume and it will be more concentrated. If ADH is low then less water is removed and the urine volume is large and more diluted. For the salt group‚ eating potato chips and drinking the salt solution increased the amount of sodium in the blood‚ leading to more water reabsorption and water retention. The increased Na in the blood will be filtered into the nephron. The increase makes the sodium transporters not
