|
|
|
Application of pressure increases the rate of diffusion
|
|
|
Higher temperature results in a faster rate of diffusion
|
|
|
The solubility of the solute does not affect the rate of diffusion.
|
|
|
The higher the density of the solvent, the slower rate of diffusion
|
Detailed explanation-1: -Answer and Explanation: The statement about diffusion that is false is 1) Simple diffusion depends upon specific carrier proteins.
Detailed explanation-2: -Complete answer: The electrical charges of the diffusion particles are the only factor that does not have an effect on the rate at which diffusion occurs.
Detailed explanation-3: -The rate of diffusion is affected by many factors like pressure and temperature. In the biological system, plasma membrane of a cell acts as a selective membrane. Here, the diffusion of molecules into and out of the cell depends on the solubility of these molecules in lipids.
Detailed explanation-4: -It requires an expenditure of energy by the cell. It’s a process where molecules move from a region of lower concentration to a region of higher concentration.
