The answer is A. The left brain is also called the interpreter. This part of the brain processes information and endeavors
to make sense/ rationalize the situation based
on past experiences. This was discovered
in the split-brain research by Roger
Sperry in 1970s.
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).
