Answer:
In thermodynamics, a closed system can be described as a system which can exchange energy from outside but matter cannot be transferred from such a system. This means that the resources present on the Earth cannot be transferred or replaced and the waste can also not be removed. By understanding the concept of the closed system, humans should recognize the fact that many resources such as minerals present on the Earth cannot be replaced and hence, resources should be utilized effectively in a conserved manner. Also, as waste cannot be removed hence humans should stop forming such waste products which cannot be removed or recycled.
Explanation:
In biology, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. That is, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in the membrane voltage in which the membrane potential is more clearly positive or negative, are hyperpolarizations.
C I think, I mean it’s the only logical answer, hope this helps!
