Answer:
Fecal coliform increases the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.
Explanation:
Fecal coliform are species of bacteria that are found in the intestine of warm-blooded animals like humans etc. Hence, they are released whenever they excrete feaces. Due to this reason, the presence of fecal coliform bacteria in a water body indicates fecal discharge into that water.
The presence of excessive fecal coliform in a water body increases the amount of organic substances in the water. These organic substances are decomposed by bacteria, which causes the oxygen present in the water body (dissolved oxygen) to deplete/decrease. The depletion of oxygen in the water threatens aerobic aquatic organisms e.g fishes and they ultimately suffocate and die.

Answer:
C) 7.5%
Explanation:
Accepted value of a substance can be said to be that number or "value" that is generally accepted by scientists worldwide.
Experimental value is that value is a substance that is gotten from experiments in the lab.
Experimental error then is the percentage difference between the accepted value and experimental value.
Percentage error = [(|experimental value - accepted value|) / (accepted value)] * 100%
Percentage error = [(|37 - 40|) / 40] * 100%
% error = 3/40 *100%
% error = 0.075 * 100
% error = 7.5%
