The presence of hydrogen bond is one factor that explains the fact that ice floats over water because it has less density.
Due to this, rivers and lakes freeze from the surface whereas it is in liquid state at the bottom which allows the sea animals to survive even in colder temperatures.
Water makes up at least 70% of earth and 65% of our bodies and this property of water is essential for our lives as it maintains the survival.

Answer:
opening of sodium channels
Explanation:
Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. Sodium channels are the founding members of ion channel super-family that includes voltage-gated calcium channels, TRP channels, voltage-gated, inward rectifying, and two-pore-domain potassium channels, and cyclic nucleotide-regulated CNG and HCN channels. When the neuron becomes stimulated the voltage gated sodium channels begin to open and the membrane potential begins to slowly depolarizes and sodium enters the cell down its concentration gradient.
