Why do metals conduct electricity? Brainliest! <br> Already looked it up, so don't try it :)
Romashka-Z-Leto [24]

Answer:

Luckily I did the same thing and it was in my docs

Explanation:

Electricity is the flow of electrical power or charge. Everyday, we use electricity to do many jobs for us from lighting and heating/cooling our homes, to powering our televisions and computers. We get electricity from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources. Electricity can be broken down into some very simple, natural elements. The biggest of which is the atom. Atoms are everything.

Not only that we are made of atoms, but atoms are everywhere. It's a known fact that almost anyone should know.

aivan3 [116]

Answer:

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.

Explanation:

An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.

On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.

The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.
