Nitric oxide is unique because it:
a. dialates airways during an asthma attack
b. is not stored in vesicles but is made on demand
c. blocks the reuptake of dopamine
d. is only found in the pns
e. is both inhibitory and excitatory

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
