d. all living things are made of cells
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.

The pronunciation of the anatomic structure that conducts impulses to and from the brain and initiates reflex action to sensory information is the spinal cord.
- The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lowers it back together.
- Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
- The protection of the spinal cord, nerve roots, and many internal organs are the spine's three primary tasks. To keep your body upright, give it balance and structural support.
- Enable fluid movement. The spinal cord is surrounded by cerebrospinal fluid (CSF), which is additionally protected by three layers known as the meninges (dura, arachnoid, and pia mater). The spinal column, which consists of 33 bones known as vertebrae, houses the spinal cord.
