Answer:
Option-B
Explanation:
Dysentery is an abnormal condition that is caused by the infection of the intestine in humans. The infection could be caused by the bacteria or the amoeba.
The disease can be characterized by the cramps in the stomach, diarrhea, and the loss of blood through feces.
Untreated dysentery can lead to the loss of a large amount of blood through feces and will lower the amount of blood in humans.
This severe loss of blood will give rise to another disease called hypovolemic shock is which the heart fails to pump enough blood to the organs due to which the other organs of the body can fail to work properly.  This condition can lead to death.
Thus, Option-B is correct.

<u>Answer</u>:       D. calcium chloride 
<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>
<u>Explanation:</u>
<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>
It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>
They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
