What is the similarities between osmosis and diffusion?
They both follow the concentration gradient i.e. require no energy for the process to occur. Diffusion is the movement of particles from an area of higher concentration to lower concentration. See Brownian motion. Osmosis is the movement of WATER particles across a semi-permeable membrane from an area of higher concentration to the lower concentration in the effort to reduce the solute concentration.
How is the movement of oxygen in the body similar to movement of carbon dioxide?
They both follow a simple diffusion gradient : from high pressure to low.
What are the similarities between osmosis and diffusion?
Osmosis is a basic process in which concentrated solution diffuses to less concentrated through a membrane. Dialysis is filtering of unwanted chemicals etc from the blood of a diabetic patient employing a similar process.
What causes mass wasting?
Mass wasting is caused when there are loose rocks and soil on a mountain, then somthing moves it. Then it all falls down the mountain causing a landslide. Denver Simmons
What effects did the movement from a substance to a market economy have on American society including farmers laborers and women?
It helped the American people to get together and often times they #TurnedUp
Movement of a substance down the substance's concentration gradient?
diffusion
How long does movement occur across a concentration gradient?
As long as there is a concentration gradient. This is because diffusion occurs which is the net movement of substances from a region of high concentration to a region of low concentration.
Is movement of a substance down its concentration gradient a passive transport?
yes, Movement of substance down its concentration gradient is a passive transport because it going from high concentration to a low concentration, so it does not require any energy.
What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
Is the movement of a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What is the movement a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
The larger the concentration gradient (bigger difference between the two solutes across semipermeable membrane) the faster the rate of diffusion.
What is the energy source for co-transport?
the movement of one of the transported substances down its concentration gradient
Is diffusion an active mechanism?
False
How does difference in concentration relate to movement of substances across the membrane?
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What type of work uses ATP to pump substances across membrane?
Various pumps use ATP to move substances across membranes. The pumps are often moving substance from a lower concentration to a higher. This movement is called "against the gradient" as movement usually moves from a higher concentration to a lower to even out the concentration. It takes energy to keep this. The pumps are mostly proteins.
