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.

Wildfires are important to many grassland ecosystems because they
naturally replenish the nutrients in the soil. Wiregrass is a type of plant that
helps spread wildfires once they have started. A conservation group is
studying a cleared grassland ecosystem, where wildfires have been
suppressed for several years, and observe that the ecosystem is
experiencing a decline in both biodiversity and available nutrients for
populations. Which of these would be best for the conservation group to
do to help encourage natural wildfires in the ecosystem? *
mow down adult wiregrass plants in other ecosystems and spread the clippings
throughout the targeted ecosystem
collect seeds from healthy wiregrass plants and plant them throughout the targeted
ecosystem
start a fire using fuel-soaked wiregrass in a specific section of the targeted
ecosystem
cut down all other vegetation in the ecosystem and transplant adult wiregrass plants
to take their place
Answer:
plant more adult wiregrass
Explanation:
this is because wiregrass helps to start wildfires naturally which replenishes the soil
