A semipermeable membrane is a porous barrier that:
A. Allows for only certain sized particles to cross
B. Prevents fungal contamination
C. Can distinguish between particles - ANSWERA. Allow for only certain sized
particles to cross
Diffusion is movement of particles:
A. By filtration through a biocompatible membrane.
B. From an area of higher concentration
C. Into a vacuum created when fluids are forced through a membrane
D. Into a space created by solutions moving in counter-current flow - ANSWERB.
From an area of higher concentration

B. Fluids separated by a membrane flow in the same direction
C. Larger molecules drag smaller molecules across a membrane
D. Fluid is pulled through a restriction - ANSWERD. Fluid is pulled through a
