There 3 atoms, 1 atom is oxygen and the other two is oxygen.
Answer:
K+ ion concentration is high inside the cell under resting membrane potential.
Explanation:
Neurons generates electrical signals across its membrane called the resting potential. The resting potential is determined by the concentration gradient of ions and membrane permeability to ions.Therefore, in a resting neuron there are a concentrations gradient for Na+ and K+ ions across the membrane. The movement of ions towards the gradient through channels . The ions' movement create a resting potential by separating its charge.
Yes, this is true water is absorbed
