Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Warmer temps increase ion diffusion in a neuron
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -When temperature increases, the kinetic energy of the particles has increased. The increased motion of the particles causes them to diffuse faster. Therefore, at higher temperatures, the rate at which fluid particles will diffuse is faster than at lower temperatures.

Detailed explanation-2: -Increased temperature is generally thought to enhance neuronal responsiveness and excitability by upregulating a variety of synaptic and neuronal functions [10].

Detailed explanation-3: -Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.
