Answer:
If a neurotransmitter attaches to a ligand-gated channel and creates a potential that causes the inside of the excitable cell membrane to become less negative, and this potential travels only a short distance before dying out, it is considered to be a <u>Graded or local potential</u>
Explanation:
<em>Graded potentials, also known as local or generator, are generated by an excitatory neurotranmitter, usually a ligan gated channel</em>, they occur at a localized place on the cell and their potentials are smaller (from 1-50mV) and its magnitude depends on the strength of the stimulus.
I hope you find this information useful and interesting! Good luck!
Explanation:
For any enthalpy change in a chemical reaction, (exothermic/endothermic), the activation energy must be reached so as to break the strong chemical bonds between the reactant molecules.

Diffusion occurs because of the movement of molecules from
the region of higher concentration to the region of lower concentration. This
movement of molecules occurs due to a thermal motion. Diffusion normally occurs
between two compartments having difference in concentration. In case of fluid
it moves from the region of higher concentration to the region of concentration
until a balance is reached. The process of diffusion is very important for the
humans as well. The oxygen that humans breathe in gets diffused with the blood.
