The area in the middle between the arrows, represented by " << --<< -- << -- << ", is a section of an axon in a state of rest.
What is electrical impulse?The electrical impulse is transmitted from the sinus node to the atrioventricular node (AV node).
There, impulses are temporarily slowed before continuing down the conduction pathway into the ventricles via the bundle of His.
An electrical impulse, or action potential, is shown moving through an axon in the diagram.
During an action potential, the membrane rapidly depolarizes, causing the inside of the cell to become positively charged relative to the outside. The arrows pointing to the right, or ">>", represent this depolarization.
The area in the middle, on the other hand, represents the repolarization period, during which the membrane potential returns to its resting state.
The arrows pointing to the left, or "<<", indicate that the inside of the cell is becoming more negatively charged in comparison to the outside. As a result, this section of the axon is at rest.
Thus, this is the area that is showing that axon is at rest.

Here are all the facts:
A girl, lets call her Grace, is wondering which pet she should get. she has owned a betta fish before, and has done a lot of research for hermit crabs. But here are some things she doesn't know:
1. Which one is easier to care for? Betta fish or hermit crab
2. Will a hermit crab be ok in a five 1/2 gallon tank?
3. Is it ok if she just gets one hermit crab or should she get multiple?
4. And ultimately, which one should she get, hermit crab or betta fish?
The last one is the most important. Thanks!
Answer:
1. Betta Fish
2. Yes. Choose a terrarium that has at least 5 gallons of space per 2 crabs.
3. They require companionship! Hermit crabs, despite their name, are social creatures that thrive best in groups of two or more.
4. Both are entertaining, but I prefer betta. Hermit crabs, in my experience, are extremely sensitive and difficult to keep alive. Hermit crabs proved to be much more difficult than I anticipated, but bettas are a little more straightforward. That is just my opinion; I am sure you will do fantastic with whatever you choose.
I hope this helps you
