Uchida’s optical imaging research showed that as the length of the carbon chain increases, the area of activation is
a. randomly distributed across the glomeruli
b. located more to the right
c. more centrally located
d. located more to the left

the area of activation is: located more to the left
This shows that a difference group of chemicals will activate different location on the olfactory bulb. The same pattern always occurs during large chain length that shows it's located also to the left

Wouldnt it be millileter
