The correct answer is option D, difficulty of redesigning workable ecosystems
Reason -
The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.

When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
