1 (also grade especially in North American English)the degree to which the ground slopes, especially on a road or railwaya steep gradienta hill with a gradient of 1 in 4 (or 25%)2 (technical)the rate at which temperature, pressure, etc. changes, or increases and decreases, between one region and another
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.
t
Divide the height of the ramp by the length of the ramp (rise over run).
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.
There is less friction from the bed and banks of the river downstream (where the gradiant decreases) so the velocity increases.
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.
A pressure gradient is the change in pressure over a specific distance. It is often used to describe how pressure changes in the atmosphere or in a fluid system. Pressure gradients often drive the flow of fluids from high pressure areas to low pressure areas.
Pseudohearts are structures that resemble the shape of a heart, but do not have the same function or characteristics as a biological heart. They are often used in the context of art, design, or symbolic representations.
A straight line will have a constant gradiant, so its change in height over time will be some multiple of x. We'll call this bx. The other point of consideration is where the line crosses the y axis (x=0). We'll call this point a. So the equation of a straight line can be given as y=a+bx
I sugest you look up "steam tables". Since convection currents are caused solely by diferences in density ... yes, it is assumed that tempreture diferences CAUSED the density gradiant - but that is not always true.
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.
The anatomical arrangement of the loop of Henle is crucial for creating a concentration gradient in the kidney that allows for reabsorption of water and solutes. This concentration gradient is essential for the kidney to regulate water balance and concentrate urine.
