Which of the following explains how polar molecules form? o a. electrons are more attracted to one of the atoms involved in a bond b. the two atoms in a bond share electrons equally o c. protons are more attracted to one of the atoms involved in a bond. o d. one atom transfers its electrons to another atom.

A. Electrons are more attracted to one of the atoms involved in a bond, this causes the bond to have an asymmetrical shape which explains why electrons are mostly attracted to one (or many) certain atoms

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
