A concentration gradiant is a common term used in Biology to signify that one side of a membrane contains a significantly higher amount of ions/atoms/molecules than the other side. This esentially means that in a concentration gradient you have stored energy. This is a common term used when talking about the formation of ATP.

Is osmosis form of active transport or passive transport?
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
What is osmosis in detail?
Osmosis is the movement of water across a partially permeable membrane down the concentration gradiant from an area of high concentration to an area of low concentration until an equilibrium is achieved.
What is pseudohearts?
They are fake hearts...mainly found in earthworms, these pump blood around the body to maintain a high concentration gradiant.
Is osmosis trans active?
Osmosis is a passive form of diffusion as it travels downa concentration gradiant, as opposed to active transport; a type of diffusion that can go against a conc. grad.
Contrast active and passive transpot.?
PASSIVE TRANSPORT: when there is a transport of solutes from there higher concentration to their lower concentration across the semipermeable membrane as plasma membrane without any utilization of energy is called passive transport. ACTIVE TRANSPORT: When there is a net flow of solutes from there low concentration to their high concentrain of flow against the concentration gradiant with the utilization of energy is called active transport. e.g. Na+- K+ exchange pump.
An exercise bicycle that is stationary and can simulate differences in terrain and gradiant?

How do you work out the gradiant on a ramp?
Divide the height of the ramp by the length of the ramp (rise over run).
Why do rivers speed up even when the radiant decreases?
There is less friction from the bed and banks of the river downstream (where the gradiant decreases) so the velocity increases.
Is osmosis an active transport?
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
Why is the anatomical arrangement of the loop of henle so important?
Because it allows the creation of an osmolar gradiant between the outermost and the innermost parts of the renal medulla. This process is important in the dilution of urine.
What is the difference in the concentration of a substance across a space is called concentration?
Concentration Gradient
What is isotonic concentration?
Isotonic concentration is when the concentration of soletutes inside and outside of the cell are equal in concentration
