Assume that the government of Krusho requires bribes to approve certain projects. MNCs that attempt to do business in Krusho must deal with: a. protective barriers. b. regulatory barriers. c. "red tape" barriers. d. ethical differences.

D. Ethical differences

Explanation:

Ethical differences usually emanate when two parties hold conflicting ethical beliefs of what is right and wrong, or do not hold similar grounds on how a particular thing should be done. As a result of the differences in the acceptable custom or conduct, ethical differences arise between both parties. Since it is the custom and norms of the government of Krusho to require bribe for the approval of certain projects, of which might run contrary to the ethical beliefs of MNCs, dealing with this ethical difference is what MNCs must face doing business with them.

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.
