D.osmotic pressure

Answer 1

c

Answer 2

the answer is C. ENDOCYTOSIS...

"Endocytosis is a process whereby cells absorb material (molecules such as proteins) from the outside by engulfing it with their cell membrane. It is used by all cells of the body because most substances important to them are polar and consist of big molecules, and thus cannot pass through the hydrophobic plasma membrane."

Answer 3

it should be endocytosis=ventricles bud into cell AND exocytosis=fusion of vesicles or vacuoles with the plasma membrane that results in secretion outside the cell
