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
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.
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.
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.
The amount of water in the stream and the gradient. However if you had two streams both with the same amount of water in them but with one stream flowing down a steeper slope (gradient) than the other, then the steep one has more ability to erode.
Wind flows from areas of higher pressure to areas of lower pressure. The Coriolis effect influences wind direction by deflecting its path to the right in the Northern hemisphere and to the left in the Southern hemisphere.
similar to potential energy, water flows down a gradient from higher potential to lower potential. Higher potential is generally in the soil/roots and lower potential is at the leaves/atmosphere. The water has potential to flow down the 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
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.
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
Simple diffusion
ATP.
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.
Water moves between cells by osmosis, down a concentration gradient.
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).
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.
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.
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.
