Silk Road

Words: 378 (2 pages)

APlan of Investigation This investigation attempts to analyze the Silk Road’s impact on cultural diffusion. The Silk Road was a trade route connecting Eastern China to the Mediterranean regions. It was incredibly important because it brought Europe, Asia, and the Middle East together in trade, and allowed them to trade goods and ideas. The parameters…

The Diffusion of a Cell


Words: 1976 (8 pages)

When substances are brought in contact with each other they intermix, this property is known as Diffusion. This property of diffusion takes place very rapidly in case of gases and to a lesser extent in case of liquids, whereas solids do not show this process of diffusion with each other. But what we can observe…

The Resting Membrane Potency


Words: 2085 (9 pages)

Introduction The resting membrane potency ( RMP ) is an electrical potency difference in cells, happening across their plasma membranes. The cytol of the cell is electrically negative in comparing to the environing extracellular fluid, this difference in electrical charge gives rise to the RMP. The RMP is indispensable for the operation of many electrically…

The Effect of Molecular Weight to the Diffusion Rate of Substances


Words: 1809 (8 pages)

The Effect of Molecular Weight to the Diffusion Rate of Substances[ 1 ] The consequence of molecular weight to the rate of diffusion of substances had been obtained through agarose-water gel experiment. Drops of the undermentioned dye samples were used as controlled variables: K permanganate, K bichromate and methylene blue. Each dye has a molecular…

Diffusion of a Liquid.


Words: 407 (2 pages)

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature, molecular weight, and movement. To test the rate of diffusion a drop of dark…

Egg Osmosis – Research Experiment




Words: 1050 (5 pages)

Introduction Many might think that an egg is made up of cells, when in actuality and egg itself is a cell. An egg has several main parts, including the egg shell (that acts as the cell membrane), the egg yolk and the egg white. There’s also a tiny white mass that is very important, it’s…

This lab was performed to understand the procedure of diffusion and osmosis. First away, to to the full grok the point of this lab, one has to be on familiar footings with the workings of diffusion and osmosis. The random motion of molecules that go from a part of high concentration to a part of…

Frequently Asked Questions about Diffusion

Don't hesitate to contact us. We are ready to help you 24/7

What is diffusion and why is it important?
Diffusion can occur across partialy permeable membranes, such as those surrounding cells. Therefore, diffusion is involved in the movement of important molecules into and out of cells. It is important for the uptake of substances needed by cells, and also the removal of waste products produced by the cells.
What is diffusion explain?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. ... The rate of flow of the diffusing substance is found to be proportional to the concentration gradient.
What is diffusion paragraph?
Diffusion is the tendency of molecules to spread out in order to occupy an available space. Gasses and molecules in a liquid have a tendency to diffuse from a more concentrated environment to a less concentrated environment. Passive transport is the diffusion of substances across a membrane.
Why is diffusion so important to humans?
Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
