Diffusion

Dialysis, however, does not correct the compromised endocrine functions of the kidney. Its treatments only replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal). Principle Dialysis works on the principles of the diffusion of solutes and ultrafiltration of fluid across a semi-permeable membrane. Diffusion is a property of substances in water; substances in water tend to move…

“Why are cells so small?” The concept of this investigation is to examine which method of diffusion is the best explanation to why cells are small. The transpiration of cells nutrients apparat in different ways; one way is Osmosis. Osmosis is the diffusion of water. Active transport requires ATP to transport nutrients and then there is diffusion, which is the process of moving nutrients from an area of high concentration to an area of low concentration. The first explanation studied is that…

the cell. Since the cell membrane is selectively permeable, it only allows certain molecules to pass through, and therefore plays a large part in controlling the movement of substances into and out of the cell. It also plays a large role in the diffusion…

Introduction The experiment will be working with diffusion and osmosis; it will test if the starch will travel through the semi permeable membrane (dialysis tube) causing osmosis. Diffusion is when a substance is highly concentrated turns into a lower concentration, and is evenly distributed throughout. An example of diffusion is when you cook and the smell of food flows until it in dynamic equilibrium; which is the even distribution of the substance. Osmosis is the movement through a semi…

movement of solvent molecules through a semipermeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. Osmosis also refers specifically to the diffusion of water molecules. Diffusion is the movement of chemical particles for an area of high concentration to an area of low concentration.The semipermeable is a material or membrane allowing certain substances to pass through it but not others.Large molecules…

Diffusion is high to low it involves no ATP nor does it need protein channels. Osmosis is a type of diffusion, it is the movement of water across a semipermeable membrane. Like diffusion there are no ATP but does need channels. There are a few terms to know when evaluating the levels of the solutes. Isotonic is when the levels are equal compared…

move in and out without expanding energy; which is called passive transport. Think about molecules and ions move in motion in a solution. When a random motion cause a net movement of a substance of high concentration to low concentration is called diffusion. That is where the molecules spread out evenly throughout the area. When you have a difference in the concentration in a distance is called a concentration gradient. Random movement of molecules are called Thermal Molecular Motion. There are…

Hypothesis: Throughout my observations and my education of the process of Osmosis, the movement of the solutions moving up from the “mysterious” solution inside the semi permeable membrane which is known as the dialysis bag. Osmosis happens because of the molecules crossing, for more of an understanding according to Anita H, she says “…high water concentration to an area of low water concentration through a partially selectively permeable membrane” (Anita) The molecules cross from less…

Osmosis is the net movement of water towards higher concentration. In osmosis experiment, water likes to diffuse from an area of low-solute concentration to an area of high-solute concentration. The purpose of the osmosis experiment was to observe the diffusion of solutes and the osmosis of water through a semipermeable membrane, which was dialysis tubing. This experiment was done to examine, if the solution is hypertonic, hypotonic or isotonic. The result of this experiment was that…

Movement of materials from areas of high concentration to areas of low concentration id diffusion. Osmosis is diffusion of water. Tonicity compares the environment inside of a membrane with the outside. When a membrane bound structure has a higher concentration of water on the outside of the membrane than the inside is hypotonic. Hypertonic is when a membrane bound structure has a higher concentration of water on the inside of the membrane than the outside. When something is isotonic the inside…
