Answer:
Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.
Amoeba and some bacterias are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area.
Where as humans have small surface area: volume so diffusion is very slow or does not take place at all.
Explanation:
As the ratio gets smaller, it takes longer for items to diffuse.
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.
When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.
this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.

The major pathway of communication between the right and left hemisphere is the corpus callosum.
- The cerebrum is the recognizable gray covering of the human brain, appearing to comprise the majority of its mass.
- The cerebral cortex is the wrinkly area; the remainder of the anatomy is hidden behind that layer.
- The longitudinal fissure, which is a significant gap between the two sides of the cerebrum, exists.
- It divides the brain into right and left cerebral hemispheres, which are two independent parts.
- The main channel for communication between the two hemispheres of the cerebral cortex is provided by the white matter of the corpus callosum, which is located deep inside the cerebrum.
