Question

what is the correct label for letter c?
choose
phospholipid bilayer
carbohydrate chain
channel protein
phosphate head
fatty acid tails
how does the cell membrane maintain homeostasis within the cell? *
by controlling the internal environment through selective permeability
during diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will
move across the membrane to the inside of the cell
continue to move across the membrane in both directions
move across the membrane to the outside of the cell
stop moving across the membrane

Explanation:

The structure labeled C in a cell - membrane diagram is typically a phosphate head. Phospholipids in the cell membrane have a hydrophilic phosphate - head that faces outward, interacting with the aqueous environments inside and outside the cell. In diffusion, when the concentration of molecules on both sides of a membrane is the same, dynamic equilibrium is reached, and molecules continue to move across the membrane in both directions.

Answer:

Phosphate Head
continue to move across the membrane in both directions
