<span>Epithelial tissue is densely packed cells that used most in the area where protection is needed. This cells mostly used in skin, some with more keratin which will increase their ability to protect. In bone, the main protective layer is calcium mineral which was deposited by osteocytes. Because this bone doesn't really need more epithelial cells. Bone tissue only needs a good vascularization and connective tissue to support it.

The correct answer for this question is ion concentration gradient.
The membrane potential at which an ionic species is at equilibrium, that is, when there is no net movement of the ion across the membrane, is known as the Nernst potential for that specific ionic species. The equilibrium potential (Ve-.) for an ion is hence the Nernst potential for that ion.
Na+ and K+ have equilibrium potentials of +60 mV and -88 mV, respectively, in mammalian neurons. The Nernst equation, where R = gas constant, can be used to determine the reversal potential for a given ion.
The membrane potential that precisely balances the concentration gradient of an ion across the membrane is known as equilibrium potential.

Why does the paper not flutter?
What factors might cause this?
Would the scenario be different if there was a fan nearby?
I hope this is what you were looking for, and that it helps you!
