Introduction There are many different factors that can influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that

that the lower the concentration of the solute‚ the faster that osmosis will happen in the solvent. To start we grabbed 5 strips of dialysis tubing‚ 10 orange clamps‚ and beakers labeled 1 through 5. After we got those supplies we soaked the dialysis tubing until it softened. We then clamped on end of each dialysis tube. After this was done we filled each dialysis tube with 10 mL of a specific concentration of liquid and then clamped the other end. One with tap water‚ one with 20% sucrose‚ one with

and analyze various factors that affect the process of diffusion and osmosis. We observed that the permeability of the dialysis tubes‚ which is our permeable “membrane”‚ depends on the concentration of the sucrose‚ not only is it important how permeable the tube is but also the rate at which osmosis is occurring. Water moves across the selectively permeable membrane of the dialysis tubing much easier than sucrose sugar does. The water moved to reach equilibrium between the solutions. Sucrose must be

How Carboplatin Is Given: • Carboplatin is usually given by infusion into a vein (intravenous‚ IV). • Carboplatin can also be given intra-peritoneal‚ directly into the peritoneal cavity in the abdomen. • The amount of Carboplatin you receive depends on many factors‚ including your height and weight‚ your general health or other health problems‚ and how your body responds to it.

Chronic Kidney Disease (CKD) is a disease that makes kidney not as functional. The reason behind this is that it’s either from a long-term course

There are no miracle drugs that can revive a failed kidney‚ leaving dialysis or kidney transplantation as the only possible treatments. By legalizing organ selling lives would be saved. Dialysis is harsh‚ expensive‚ and‚ most importantly it is only temporary. Acting as an artificial kidney‚ dialysis mechanically filters the blood of a patient. It works‚

Introduction: The purpose of this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy. This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the passive movement of molecules

observe diffusion happening within the cells‚ and to help understand the sizes of molecules and how the chemical reactions take place. Therefore‚ the experiment was conducted using glucose and starch solution inside the dialysis tube. The starch and glucose that was put inside the dialysis tube help identify which of the two will reacted with potassium iodide inside the breaker‚ as the latter passed from the beaker into the tube‚ the glucose/starch solution’s change of color showed that the potassium

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

We then securely tied both ends of the tubing and placed it in a large beaker‚ two-thirds filled with water. We then added 4 pipettes of Lugol’s reagent to the beaker and let it sit for one hour. Next‚ we took a control with just starch in dialysis tubing and placed it in a large beaker‚ two-thirds filled with water. We added 4 pipettes of Lugol’s to the water and also let this sit for 1 hour. At the beginning of the experiment‚ the starch was a cream color‚ the amylase was clear‚ the mixture
