Factors that determine the rate of stream erosion-
➡️ Rainfall (more rain more erosion). ✔️
➡️water velocity ✔️
➡️shape, size and depth of channel ✔️
➡️stream capacity to transport eroded material, and the nature of the material being transported✔️
➡️Gradient (Steepness or slope) ✔️
➡️Discharge (Amount of water carried at a given time) ✔️
➡️Load (The materials carried by a stream)
Rainfall (more rain more erosion). ✔️
➡️Slope (the steeper the slope the faster the water will flow) ✔️
➡️Geology (if the bedrock is a soft silt it will erode faster than granite).✔️

The active transport of the sodium and potassium pump must work to maintain: A high concentration of sodium outside the cell and a high concentration of potassium inside the cytosol in order to maintain a resting membrane potential.
Active transport in cellular biology refers to the movement of molecules or ions across a cell membrane against the concentration gradient from a location of lower concentration to a region of higher concentration. Cellular energy is needed for active transport to achieve this movement.
The electrical potential differential across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is often used to indicate the difference across a cell membrane.
