Answer:
Depolarized graded potential.
Explanation:
A depolarizing graded potential is a local change in the membrane potential that makes a small increase in the potential. The membrane potential is less negative because the graded potential caused the entrance of Ca²⁺ or Na⁺ ions to the inside of the cell decreasing the negative voltage in the inside of the cell.
Answer:
A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. Hydrogen bonds can occur between molecules or within parts of a single molecule.
