Answer:
They have increased the amount of certain organisms (a lot of crops and such) and made the soil healthier. Also, other organisms that may feed on this are having more food.
Explanation:
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;
Carbohydrates;
The macromolecule that provides a person with most of the energy that is needed for daily activities is carbohydrates.
Explanation;
-Biological macromolecules fall into four categories: carbohydrates, proteins, lipids and nucleic acids. The body uses carbohydrates, lipids and proteins for energy.
Carbohydrates are the main source of energy and for structural purposes, Lipids are used to store energy; important parts of biological membranes and waterproof coverings, Nucleic acids helps to store and transmit hereditary or genetic information. Proteins functions as a source of energy and to control the rate of reactions and regulate cellular process.
Hydrogen bonds are classified as weak because they are formed fast, but they also break easily under normal biological conditions.
Weak bonds can be easily broken, but this is extremely important because they are in bold in biological systems. For example, they help to decide and stabilize the shapes of water molecules.
