Question

cell drinking, cell eating. both are modeled here and are examples of
a osmosis
b diffusion
c endocytosis
d facilitated transport

Explanation:

The question mentions "cell drinking" (pinocytosis) and "cell eating" (phagocytosis), which are both types of endocytosis—processes where cells engulf substances by forming vesicles from the cell membrane. Osmosis is water movement across a membrane, diffusion is passive movement of particles, and facilitated transport uses proteins for passive movement; none match the described processes.

Answer:

C. endocytosis
