diffusion distance increases‚ concentration gradient increases‚ surface area increases‚ temperature increases‚ and many more. 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? a. I think the urea was not able to diffuse through the 20 MWCO membrane because the urea was too big to pass through. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the

The Urea test was used to test both Unknown Gram-positive and Unknown Gram-negative bacteria. One colony of bacteria was used from the Unknown 13A plate and Unknown 13B plate in order to inoculate the Urea Slant. After the slant was inoculated‚ the cultures were placed in an incubator at 35ºC for Gram-positive bacteria‚ and 37ºC for Gram-negative bacteria for a total of 48 hours. If the Urea test were positive‚ the color of the slant would have changed to a hot pink color‚ which indicated the bacteria’s

Details of the nephron‚ the functional unit of the kidney (right). The product of the kidneys is urine‚ a watery solution of waste products‚ salts‚ organic compounds‚ and two important nitrogen compounds: uric acid and urea. Uric acidresults from nucleic acid decomposition‚ and urea results from amino acid breakdown in the liver. Both of these nitrogen products can be poisonous to the body and must be removed in the urine. Nephron The functional and structural unit of the kidney is the nephron. The

Urea is produced when your body breaks down food rich in protein‚ it is then carried in the blood stream to the kidneys which removes it from the blood. The urea is removed from the blood by miniscule filtering units within the kidney called nephrons. Urea‚ along with water and other waste substance‚ forms urine as it passes through the nephrons and down the renal tube to the

NaCl‚ Urea‚ and Glucose at MWCO 200 5. Which did not? Why? Albumin‚ too large to diffuse Activity 2: Simulating Dialysis 1. What happens to the urea concentration in the left beaker (the patient)? It mixes with the water to balance out the structure. 2. Why does this occur? Molecules are moving around to make space. Facilitated

So they add different adulterants like water‚ starch‚ urea‚ flour and vegetable oil in milk to increase its quantity. Another important thing which compels them to do adulteration (addition of anything which is not the entity of milk naturally) is that milk has less shelf life as 3-4 hours after milking. To
