Which of the following practices that are needed to run a nuclear power plant has a negative impact on both air and water?

a.
cooling of the power plant
b.
mining of uranium
c.
storage of radioactive waste
d.
monitoring the reactor

The correct answer is option B

The mining of uranium is harmful for both air and water. Uranium is a radioactive compound that is extracted by mining.

Uranium ore emits the gas named radon. The health effects of exposure to radon have particular problems. Significant rate of lungs cancer was observed during the 1940s and 1950s.

Water is used in the heap leaching of the uranium mining. The water can get mixed into the normal supply of water and harm the health of people.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
