Answer:

diffusion through a selectively permeable membrane

Explanation:

The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.

Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances  from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.

The diffusion through a selectively permeable membrane is an example of passive transport.

The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.

Drag labels to the appropriate locations in this diagram.
Vinil7 [7]

Answer:

c = Enzymatic activity

e = Attachment to ECM and cytoskeleton

f = Signal reception and relay

g = Transport

h = Intercellular junctions

i = Cell-cell recognition

a = Phospholipid bilayer

b = Fibers of extracellular matrix (ECM)

d = Microfilaments of cytoskeletons

Explanation:

c) Enzymatic activity is an indication of the amount of active enzymes present to increase a reaction rate

e) Attachment to ECM and cytoskeleton is enabled by integrins that take signals from the ECM and control signaling pathways of the cell

f) Signal reception and relay is the transduction of signal

g) Transport is the movement of matter in and out of the cell through the cell membrane

h) Intercellular junctions are the contact regions between adjacent cells and plasma membrane

i) Cell-cell recognition is power of the cell to decipher the different neighboring cells in the cell's environment

a) Phospholipid bilayer consists of a hydrophobic interior and a hydrophilic exterior

b) Fibers of extracellular matrix (ECM) are ECM associated the cell

d) Microfilaments of cytoskeletons consist of actin and aid in cellular movement.
