1. Which of the following is TRUE about the polarity of water? (1 Point)

A- electrons are more strongly attracted to the H atom.

B- electrons are shared equally between all atoms within the molecule.

C- electrons are more strongly attracted to the O atom.

D- only H atoms have electrons.

The answer is C. Electrons are more strongly attracted to the O atom

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.
