I believe the correct answer from the choices listed above is the last option. In tRNA, t stands for transfer. It <span>is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length. Hope this answers the question. Have a nice day.</span>
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!
