Answer:
Ozone
Explanation:
Ozone is considered a pollutant in the troposphere, but in the stratosphere it is essential to life on earth because it absorbs biologically harmful UV radiation. The mesosphere and the thermosphere are two additional atmospheric layers above the stratosphere.
Answer:
By the numbers, humans produce a lot of food—enough to provide every person on Earth 2,750 calories per day, exceeding almost all dietary recommendations.
There’s one glaring problem, however: Humans aren’t producing enough of the right food.
When researchers at the University of Guelph in Canada broke those calories down into different food groups, they found a shortage in production of the most important foods. In the long run, with the global population expected to balloon to about 10 billion people by mid-century, this could cause some serious problems.
Explanation:
All macromolecules have carbon atom and the hydrogen atom.
<h3>What are macromolecules?</h3>
The term macromolecules refers to the molecules that are composed of smaller units. These smaller units are called monomers. The macromolecules that we are concerned with here are the macromolecules that could be found in the human body.
The biological macromolecules are often very large as we can see. This is because the number of units that are joined to form the macromolecules are usually very much. There are thousands of monomer molecules that are joined together to give proteins, lipids, carbohydrates and the nucleic acid macromolecules.
All the macromolecules have the carbon atom and the hydrogen atom. These are found across all the macromolecules. The carbohydrates are reducing sugars thus they contain the carbonyl bond. The carbonyl group is absent in lipids, nucleic acids, proteins, and amino hence they do not undergo carbonyl reduction reactions.
