In case of a Natural Disaster, taking the decision about who must receive the benefits of a donation is "a locus of authority".
<u>Option:</u> D
<u>Explanation:</u>
A locus of authority arises when questions are raised about who is accountable or under which jurisdiction anything falls. In the scenario of some health, law or environmental (natural disaster) emergency the central or state governments are responsible for releasing funds to rescue the region by providing basic needs like food, medical aids, etc.
This phase is very important for the head of nation because allocating fund is easy but in right hands is trick, so the authority to whom fund is handover for further processing via right channel and to targeted audience is uttermost priority, also in time.

Liver cell Vs Nerve cell</h2>
Explanation:
-  b. liver cells can reproduce while the nerve cells cannot.
Liver cells , the fundamental units of liver are called hepatocytes. Hepatocytes secrete bile that helps in digestion by emulsifying fats. Hepatocytes are capable of dividing and they can regenerate damaged parts of the liver.
In contrast,
Nerve cells, the fundamental unit of nervous system are neurons. Neurons are longest cell of the human body and they contain a cell body and a long axon. Neurons conduct nerve impulses. Neurons are incapable of dividing and hence once damaged neuron cannot be replaced.

Answer:
The correct answer would be ATP.
ATP (adenosine triphosphate) is an energy currency of the cell, that is, it provides energy for all cellular activities.
Muscles also get energy in the form of ATP for movement.
Usually, simple sugar such as glucose is oxidized completely to produce ATP.
Then, ATP hydrolysis releases energy in the form of heat which is used by cells to perform various functions such as movement, repair, et cetera.
