The answer for this one is B. I hope I help! :)
A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.
As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.
The real membrane potential will be between NA+ and K+ of equilibrium potential<span>. However, it will be closer to the equilibrium potential of the ion type with higher permeability.</span>
The best phrase is 'natural selection is a process that causes evolution '. Natural selection can also be referred to as selection pressures within a population that favour particular traits that enable the population to better adapt to its habitat. It's could be better camouflage, high sense of smell, and etcetera. These traits are preserved while those that cause disadvantage are diminished. This causes evolution of the population .
