Describe two variables that affect the rate of diffusion. Size of material and concentration 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? The molecules were too large to pass through. This is what I predicted

mammary arteries‚ which are inside the chest wall‚ or the greater saphenous veins‚ which are in the leg. These vessels are "spares." Blood flow is usually not affected by removing them. Less often‚ the radial artery in the arm may be used for a graft. Grafts usually last for 10 to 12

gradient. The energy source ATP is used during this process to move the particles across the cell membrane. This experiment takes place to measure the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ allowing larger molecules to pass through‚ but slowly. Dialysis is the movement of a solute through a selectively permeable membrane. When the two solutions on either sides of the membrane are equal and no net movement is detected‚ the solutions

Philippine History During the Japanese Occupation On December 8‚ 1941‚ the Japanese invades the Philippines hours after bombing Pear Harbor in Hawaii. While the forces of Gen. Douglas MacArthur retreated to Bataan‚ the Commonwealth government of President Quezon moved to Corregidor Island. Manila was declared an open city to prevent further destruction. After the fall of Bataan on April 9‚ 1942 and Corregidor‚ In March 1942‚ MacArthur & Quezon fled the country and by invitation of President Roosevelt

is not a generator. The patient will lose the blood if not returned quickly. In the event of a power outage‚ manually the health care provider should crank the machine to return the blood. In the event of a fire the patient is to be taken off the dialysis machine without returning the blood. In the event of a crisis keeping communication lines open‚ clear‚ and concise is essential. In a health care setting a crisis will make the patient very uncomfortable‚ and possibly frantic. The nurse must reassure

resources. This divide continues to widen when involving limited resources and who deserves them. This idea is expressed in the story of Horacio Alberto Reyes-Camarena‚ a death row inmate receiving dialysis due to kidney failure. He desires a tax-payer funded kidney transplant in order to discontinue his dialysis treatment. Regrettably‚ kidneys are in high demand with over one-hundred thousand people waiting for a kidney transplant at the beginning of this year (“Organ Donation and Transplant Statics”)

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass
