Diffusion is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached.
The rate (speed) of diffusion depends on:
1) concentration gradient (the more molecules there are, the faster the distribution ; the more crowded the molecules are, they distribute more rapidly).
2) size of the molecules (smaller substances diffuse faster)
3) chemical composition (molecules that can easily dissolve in the bilipid cell membrane can diffuse faster).
Answer: Cornea
Explanation: The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.

Answer: the cell wall and are especially useful in controlling gram-positive bacteria
Penicillin is a group of drug/antibiotic that works by inhibiting the formation of cross-link of the peptidoglycan. Peptidoglycan is a protein that commonly found in bacteria cell wall, but it was much thicker in gram-positive bacteria. Since the drug disrupt the production of material that responsible for cell wall, it will weaken the membrane and induce lysis.
