"active transport is when molecules diffuse from a higher concentration to a lower concentration. facilitated transport is when
proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion. the lipid bilayer opens up, allows the ions or molecules to enter the cell, and then closes. diffusion, or passive transport, is when molecules diffuse from a lower concentration to a higher concentration."
Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration— against concentration gradient Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins. Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration.
I can’t see the model but perhaps the pimple has stayed in the persons skin to long and grew infected? Like I said I’m sorry but I can’t see any “model” but I do hope this helps.

At the end of the esophagus is a thick ring of a muscle called a sphincter which allows food to enter the stomach but not from the stomach back into the esophagus. Once the food enters the stomach it is mixed with the digestive juices.
