A steep diffusion gradient is maintained by ensuring a high concentration of molecules in one area and a low concentration in another. This can be achieved through continuous processes like active transport, where energy is used to move substances against their concentration gradient, and by removing or utilizing those substances in the lower concentration area. Additionally, factors such as increased surface area and efficient circulation can help sustain the gradient.
What else can I help you with?
How is the rate of diffusion affected by an decrease in the concentration gradient?
A decrease in the concentration gradient slows down the rate of diffusion. This is because diffusion occurs from areas of higher concentration to areas of lower concentration, and a smaller difference between these concentrations reduces the driving force for movement. Consequently, when the gradient is less steep, molecules move more slowly and take longer to reach equilibrium. Thus, the overall rate of diffusion diminishes as the concentration gradient decreases.
In a typical stream where the gradient is steep the discharge is what?
A steep gradient will force the water to flow downhill faster.
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
How is the carbon dioxide gradient maintained within the amoeba?
The carbon dioxide gradient within an amoeba is maintained through cellular respiration and diffusion. As the amoeba metabolizes nutrients, it produces carbon dioxide, which accumulates in the cytoplasm. This concentration gradient allows carbon dioxide to diffuse out of the cell into the surrounding environment, where the concentration is lower. The continual uptake of oxygen for respiration helps to further sustain this gradient by keeping carbon dioxide levels within the amoeba in check.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
How is the rate of diffusion affected by an decrease in the concentration gradient?

Consequently, when the gradient is less steep, molecules move more slowly and take longer to reach equilibrium. Thus, the overall rate of diffusion diminishes as the concentration gradient decreases.
When is diffusion rate is fastest when the concentration gradient is?
Diffusion rate is fastest when the concentration gradient is steep, meaning there is a large difference in concentration between two areas. The greater the difference, the more molecules will move from the area of higher concentration to the area of lower concentration, accelerating the diffusion process. Additionally, factors such as temperature and medium can also affect diffusion rates.
In a typical stream where the gradient is steep the discharge .?
In a typical stream where the gradient is steep the discharge is small.

In a typical stream where the gradient is steep the discharge is?
In a typical stream where the gradient is steep the discharge is small.
Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
What are the features of a river channel that has a steep gradient?
If a river channel has a steep gradient, the river flows faster and has more erosive energy.
How is a concentration gradient maintained within a biological system?
A concentration gradient is maintained within a biological system through processes like active transport, diffusion, and osmosis. These mechanisms help to move molecules and ions across cell membranes, creating differences in concentration that are essential for various cellular functions.
How diffusion will occur?
diffusion is occur when different concentration gradient is applied
What must there be for diffusion to occur?
a gradient
