Reverse osmosis

Dialysis is a process used to remove waste and excess water from the blood, and it’s used mainly to provide an artificial replacement for lost kidney function in patients with renal failure. Dialysis may be used for those with an acute disturbance in kidney function or progressive but chronically worsening kidney function. Dialysis, however, does not correct the compromised endocrine functions of the kidney. Its treatments only replace some of these functions through diffusion (waste removal)…

a cell inside of a hypotonic solution, the amount of a solute outside of the cell is less than the amount of solute inside the cell. The cell has more of the solute on the inside, which means the water will move into the cell. Water will move by osmosis to the area of greater solute concentration in order to balance the amount of solute and water. If a cell receives too much water as a result of a hypotonic environment, it may lyse, or burst, because of the influx of water. Plant cells…

in a beaker of tap water for 45 minutes and the final weight was 17.98 ounces. The dialysis had a semipermeable membrane and the water soaked through the bag of the syrup. This created a solution of water and syrup 2. The plant takes up water by osmosis and starts to swell. The cell wall prevents it from bursting. Animal cells don’t have a cell wall so the cells will burst in a hypotonic solutions. 3. A wilted plant would have vacuoles are unreplenished. The lack of water causes the cell walls…

1a. Osmosis: Osmosis is the diffusion of water across a selectively permeable membrane. Cell membranes have pores that are where molecules pass through the membrane. These pores are too small for some molecules like sugar to pass through, but are large enough for water molecules. These water molecules move across the membrane from areas of low concentrations of solute to high concentrations of solute. The different concentrations affect the water level. However, when a solution is dilute, the…

The importance of tightly regulating plasma volume is to see how much water can a person excrete, and how the total amount of blood volume has a direct effect on plasma osmolarity. As a result, plasma volume has a direct effect on the blood pressure. Basically, when the blood contains low amount of water, it can result in decrease in plasma volume, and increases in serum osmolality which led to blood having increased viscosity (Evans 1. et al. 1506). Additionally, the plasma volume results in…

Based on the data collected, the color of 0.0M is clear, 0.2M is blue, 0.4M is yellow, 0.6M is green, 0.8M is red, and 1.0 is black. The relationship between the change in mass and the molarity of sucrose within the dialysis bag is directly proportional. When the mass percentage increase, so does the molarity. This is because the molarity of sucrose in the bag determines the amount of water that would either move in or out of the bag. If all the bag were to be placed in 0.4M sucrose solution…

The purpose of the experiment was to measure the amount of diffusion that has occurred over three minutes and examine the effect of the surface area to volume ratio using of agar cubes which were infused with phenolphthalein as an indicator that the acid had diffused. Diffusion is a significant process by which substances such as nutrients, water, oxygen, and cellular wasted are transported between living cells and their environment. The four different sized agar cubes (0.5cm, 1cm, 2cm, 3cm)…

The hypothesis could be proven. If water is filtered through a pine dowel, then this permeable wood will filter the impurities out of the water through the process of osmosis. The water will pass through leaving the impurities behind. This experiment did prove the hypothesis however, it may have worked better if more time was allowed for most of the water to go completely through the wood, if the wood were less dense, and if the dirt in the water wasn’t so fine. In my experiment I observed that…

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…

CONCLUSION An experiment was run to determine how a cell’s surface area to volume ratio affects its rate of diffusion. The proposed hypothesis was if a big surface area to volume ratio is something very desired by cells that need efficient and fast diffusion for their functioning (Oxygen, water, and waste), then the cube with the largest Surface area will have the most molecules diffused into the agar cube because the more surface area a cube have, the more molecules the agar cube is getting…
