Ozone is produced naturally in the stratosphere. But this "good" ozone is gradually being destroyed by man-made chemicals referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. These substances were formerly used and sometimes still are used in coolants, foaming agents, fire extinguishers, solvents, pesticides, and aerosol propellants. Once released into the air these ozone-depleting substances degrade very slowly. In fact, they can remain intact for years as they move through the troposphere until they reach the stratosphere. There they are broken down by the intensity of the sun's UV rays and release chlorine and bromine molecules, which destroy the "good" ozone. Scientists estimate that one chlorine atom can destroy 100,000 "good" ozone molecules.
Answer:
The options
A) rapidly increase.
B) rapidly decline.
C) gradually increase.
D) gradually decline.
E) remain unchanged.
The CORRECT ANSWER IS D)
D) gradually decline.
Explanation:
It will decline gradually. The causative factor for the natural deterioration is not shown when only mature adults are kept. The most apparent and favourable use of slot limits. The average median is notably observed when younger ones experience natural deterioration, middle ones are plucked with the majority of the mature ones continuing to be preserved.
In situation where the longer ones are left in captivity slowly, they tend to show more caring capacity, while those who are not kept in captivity will continue heavily and results to a reduction in length, but gradually.
Answer:
B
Explanation:
They all do help improve quality of life.
