What is the movement of a substance from an area of great concentration to an area of lesser concentration?
Molecular Diffusion
What happens in a cell transportation lab report?
When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane. This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement of substances across the cell membrane without any input of energy by the cell. The energy for passive transport comes entirely from kinetic energy that the molecules have. The simplest type of passive transport is diffusion, which is the movement of molecules from an area of high concentration to an area of lower concentration. Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space. Osmosis is a type of diffusion in which water molecules move down the concentration gradient. When the concentration of solute molecules outside the cell is lower than the concentration of solute in the cytosol , the solution outside is hypotonic to the cytosol. If the concentration of solute molecules is higher outside of the cell, the solution outside is said to be hypertonic. The solution outside is isotonic if the concentration is equal on both sides of the cell membrane.
What influences the movement of ions and molecules across cell membranes?
A membrane potential is basically the difference between the inside and outside of the cell. Ions are charged, and so will change the membrane potential (the difference between charges on the inside and outside) when they move. Please see the related link below which includes a diagram of how ions affect membrane potential.

How do other molecules pass through the selectively permeable cell membrane?
[Molecules pass through the cell membrane] through a process known as osmosis. ------------------------------------------------------- Yes, osmosis is a great part of diffusion of molecules, but another important factor to consider is the presence of protein channels in the membrane. The cell membrane is actually a lipid bilayer, in which proteins are embedded. Normally, molecules will simply be diffused through these chanells, but in some cases, the protein must be modified in order to allow the molecules to flow. This is called active transport, which requires energy in order to change the shape of the protein and allow the foreign molecule to pass.
When was Great Commission church movement created?
Great Commission church movement was created in 1970.
How many type apes in the world?
There are eight extant genera of apes, with a total of twenty-four species. These are divided into two main categories, Great Apes and Lesser Apes, each of which has four genera (seventeen Lesser Ape species, seven Great Ape species).
