The passage of materials through membranes by mechanical pressure is known as _______.
A) diffusion
B) filtration
C) active transport
D) permeability

Question

Quizplus · Accepted Answer

Filtration is the passage of materials through a membrane or filter under the influence of a physical force such as gravity or pressure, and is commonly used in processes such as kidney function and water purification. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Active transport requires energy to move materials against a concentration gradient. Permeability refers to the ability of a membrane to allow particular molecules to pass through it.
