Agriculture Science is the science of crop production and its improvement. In Agriculture Science, scientists focus on research and development on various aspects of crop technology and production.
Crop improvements include:
1. Irrigation Management as a production technique
2. Minimizing the growth of pests
3. Transformation of raw products to end-consumer products
4. Prevention of adverse environmental effects (e.g. waste management and soil degradation)
5. Supply and demand for food in a global basis 6. Crop quantity and quality 7. Study of other fields of agriculture (e.g. soil science) </span>
Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .

There are two potential alternative locations for another canal across the isthmus. These are in <u>Mexico</u> and <u>Nicaragua</u>?
An isthmus is a slim strip of land that connects two larger landmasses and separates two bodies of water. This form of the isthmus is called a tombolo and is shaped as waves and tides slowly building up a sand bar to create an everlasting hyperlink between a coastal island (known as a tied island) and the mainland.
Definitely, the 2 most famous isthmuses are the Isthmus of Panama, connecting North and South America, and the Isthmus of Suez, connecting Africa and Asia.
An isthmus is a slim piece of land connecting two large regions across an expanse of water by which they may be otherwise separated. A tombolo is an isthmus that consists of a spit or bar, and a strait is the ocean counterpart of an isthmus.
