<span>When Sodium moves into the neuron it causes a charge change in the neuron, making it very positive. It repolarizes by pumping sodium back out of the neuron, re-establishing the potential. Neurotransmitters transmit an impulse from one neuron to another chemically. Inhibitory neurotransmitters stop impulses, excitatory neurotransmitters create and encourage impulses. For an action potential to fire the threshold of the input source must be reached.</span>
Answer:
2m/s
Explanation:
The formula for speed is [ s = d/t ].
s = 8/4
s = 2m/s
Best of Luck!
<h3><u>Answer;</u></h3>
18 Joules
<h3><u>Explanation;</u></h3>
- <em><u>Work is the measures the transfer of energy when an object moves over a given distance.</u></em>
- Work is therefore given by; Force × distance
Force =36 Newtons
Distance = 0.5 meters
- Hence; <em>work = 36 N × 0.5 N</em>
<em> = 18 Joules </em>
Light year is the unit of distance. It is the distance that an object travels in one year with the speed of light.
In short, Your Answer would be "Distance"
Hope this helps!
