The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field

Why gradient decreases with distance from the river source?
The gradient decreases with distance from the river source because water flow gradually slows down as it moves away from the source. This slowing of water flow is influenced by factors such as friction, changes in the river channel morphology, and the accumulation of sediment. Consequently, the decrease in gradient is a natural outcome of these processes as the river meanders and transports materials downstream.
Does Potassium ions move across the same gradient as sodium ions?
No, potassium ions move against their concentration gradient during resting membrane potential due to the activity of the sodium-potassium pump. It actively pumps potassium into the cell and sodium out of the cell to maintain the resting membrane potential. Sodium ions, on the other hand, move down their concentration gradient during the resting state.
Where does glacier ice move quickly and slowly within a glacier?
Glacier ice moves more quickly in the center of the glacier where there is less friction with the valley walls. It moves more slowly along the sides and bottom of the glacier where there is more friction with the rock and sediment beneath it.
What does a stream's ability to erode mainly depend on?
A stream's ability to erode mainly depends on its discharge (volume of water flow), velocity (speed of flow), and the amount of sediment carried in the water. Higher discharge and velocity typically result in increased erosion potential.
What influences the direction in which the wind moves?
Wind direction is influenced by a combination of factors, including the Earth's rotation (Coriolis effect), pressure gradients, temperature differences, and geography. For example, wind tends to move from areas of high pressure to low pressure, and it is deflected in different directions depending on the hemisphere due to the Coriolis effect. Terrain features can also influence wind direction, such as mountains causing air to flow up or down slopes.
What is water potential gradient?
Water potential gradient refers to the difference in water potential between two points in a system. Water moves from areas of higher water potential to areas of lower water potential, driven by this gradient. It plays a key role in processes like osmosis and water uptake in plants.
Do electrons move up or down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
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.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
The movement of electrons down a concentration gradient via electron transport membrane is used to generate what?
ATP.
How is gradient of ions maintained in the mitochondria?
By the action of electrons going down the electron transfer chain the energy is provided to pump H + into the outer lumen of the mitochondria creating the concentration gradient for H + to come down it's concentration gradient through the ATP synthase.
Most water enters and leaves cells by?
Water moves between cells by osmosis, down a concentration gradient.
What type of diffusion moves water down a concentration gradient through a semi permeable membrane?
Osmosis is the type of diffusion that moves water down a concentration gradient through a semi-permeable membrane. Water moves from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration).
Is the The resting membrane potential is mainly determined by the concentration gradient of K plus inside the cell?
Yes, the resting membrane potential is largely determined by the concentration gradient of potassium ions (K+) inside the cell. This is due to the high permeability of the cell membrane to K+ ions, which allows them to move down their concentration gradient, establishing the negative resting potential.
What part in a circuit that produces potential difference?
The potential difference is provided by the power source, which can be a battery or some form of electric generator. Inside the source, electric charges are raised up a potential gradient, and they then give up their energy as they travel down the potential gradient in the circuit that is being supplied with energy.
What concentration gradient moves when a low concentration moves from an area of a higher concentration?
The low concentration moves down its concentration gradient from an area of high concentration to an area of low concentration. This process is driven by diffusion, where particles move spontaneously from regions of high concentration to regions of low concentration until equilibrium is reached.
How does meandering affect gradient?
Meandering generally results in a decrease in gradient because the river's path lengthens as it winds back and forth. The energy of the flowing water is dissipated as it moves through the meanders, causing the river to slow down and the gradient to decrease.
