Explanation:
According to dependency theory, the advanced center of an empire is called the metropolis.
<h3 /><h3>What is dependency theory?</h3>
It is a theory developed in the 1960s, from the theory of modernization, in respect of the problems of social inequality and underdeveloped societies in Latin America. Dependency theory asserts that poverty is derived from the exploration of underdeveloped countries.
Therefore, dependency theory relates to the enrichment of the core of rich states, or the metropolises occur according to the exploration of the periphery, that is, of poor countries and states, alluding to the situation that occurred during the American colonial past.

Answer: hyperpolarized, longer.
Explanation:
An increase in potassium ions in the cardiac tissue will enable heart rate & volume to decrease.
The extracellular potassium concentration around a myocyte increases, and the potassium gradient accross the cell membrane reduces, and in turn the resting membrane potential will be more positive. There will be more negative resting membrane potential if extracellular potassium reduces.
Lesser potassium levels in the extracellular space will cause hyperpolarization of the resting membrane potential. For action potential to be initiated, depolarization of the membrane must be done essentially by a larger than normal stimulus.
Hypokalemia results in hyperpolarization in the myocytes' resting membrane potential in the heart. When there is more negative membrane potentials in the atrium it may result arrhythmias because of a more complete recovery from sodium-channel inactivation, less likely enabling the triggering of an action potential. Futhermore, the reduced extracellular potassium reduces the activity of the IKr potassium current and make ventricular repolarization slower. A delayed repolarization may project re-entering of arrhythmias.
Popular sovereignty is government by the consent of the people. Of these options, D is the most correct because by allowing the people to choose their representatives, the citizens have some control over who goes into office, thus the people are consenting to elected representatives.
Answer:

Explanation:
It comes a time when all individuals get to a point to their lives when they wonder if their life is going somewhere either be in life or in the middle of a career or any mid-path or half-way project; it could be anywhere, anybody at anytime, though this is a precise stuck-in-the-mud epoch where one cannot have any idea, value, purpose or meaning his/her steps are heading to.
