Hydrogen bonds differ from covalent bonds. Hydrogen bonds form due to the positive charge of a molecule being attracted to the negative charge of a water molecule.
This is due to water being a polar substance. Polar substances have covalent bonds where the electrons are shared unequally. This creates a slight charge at each end of the molecule. This charge is what creates a hydrogen bond between a water molecule and another molecule. Hydrogen bonds are weaker than covalent bonds.
The solution is B.
Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.

Answer:
The nephrons of the kidneys process blood and create urine through a process of filtration, reabsorption, and secretion. Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid.
