In a journal article written by Florian Lang, osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang, 1997). Osmosis is able to maintain osmotic pressure and regulate a cell's volume.
In a hypotonic () or hypertonic () environment, a cell may be liable to gain or lose water. Osmotic pressure is known as the amount of force needed to prevent the flow of water through a membrane. Osmotic pressure allows a cell to prevent itself from shrinking or swelling and possibly …show more content…
All the sacs started with a mass within 0.3g of each other. All the sacs finished with a mass within 0.5g of each other. Each solution started with an average mass of 10.75g and finished with a mass of 13.3g. The rate of osmosis was approximately for the cell's percent change in weight.
PH does not effect the rate of osmosis.
The colorblind attitude is still a privileged attitude for whites mainly because whites get to choose. They are able to choose how they dress, and they can wear baggy clothes, turn their hat sideways, and buy the latest hip-hop CD at the same store as a black person. They
