Mesolithic age falls inbetween Pre Paleolithic and Neolithic age.
That age developed mostly hunting equipments
There were also civilization inventions like pots to store water and food ,sun-slaked clay
Answer:
Wildlife can be define as: Wild Fauna (animals) and flora (plants) in a certain area
Or it can be difined as: 'Undomesticated animal species, but has come to include all organisms that grow or live wild in an area without being introduced by humans.' also :3
Hope this helped :D
Ps: The first definition is mine, the second definition is through research :3

The writer that Woolf refers to that used a male pen name in order to hide her identity was Currer Bell - APEX
Answer:
Explanation:
Action potential
It is the potential or power or electrical energy required to generate impulses and provides communication between the neurons is called action potential. Normally cell membrane consists of potential is called resting membrane potential() -70mV. The action potential is due to exchange of different ions across the membrane.
Phases of the action potential in a neuron are
i. Depolarization- it is caused by the influx of sodium and calcium ions through the opening of voltage-gated sodium and calcium channels. sodium ion influx is rapid than the calcium ions membrane potential -70mV to +30mV.
ii. Repolarization - It causes the efflux of potassium ions into the cell through the opening of potassium channels. the membrane returning to resting membrane potential.
iii. After- Hyper polarization - in this stage the potassium channels remain open and causes re polarization and comes to normal membrane potential.
The generation of impulses(depolarization) in neuron mainly depends on influx sodium and calcium ions without these ions, no action potential developed and neuron firing does not occur.
If the drugs inhibit these channels, no depolarization, no action potential, no neuronal firing or communication.
The channels involved in an action potential are voltage-gated sodium channels, potassium channels, and calcium channels.
The action potential is required for transmission of information one are to another area in the body.
The responses to different stimuli is due to action potential.
