(A) Corona, chromosphere, photosphere
<u>Explanation:</u>
- Photosphere - it is the Sun’s deepest layer, and the layer visible to human eyes directly from the Earth. It is also called the solar surface
- Chromosphere - This layer of the Sun is located between 250 miles and 1300 miles above the photosphere. The chromosphere has temperatures around 4000K at the base, and 8000K at the top.
- Transition Region - This layer is very thin with a size of about 60 miles, and it is present between corona and the chromosphere.
- Corona - This layer is the Sun’s outermost layer. It starts at roughly 1300 miles over the photosphere and it has no upper limit. Its temperature is between 500,000 K to 1 million K.
Norman Borlaug developed high-yield crop varieties by using conventional breeding techniques. Moreover, agricultural biotechnology corporations use DNA recombinant technologies to improve crop yield.
Norman Borlaug was an American agronomist who developed high-yield semi-dwarf crops (i.e., wheat and rice) varieties during the 60s by crossing different crop varieties.
This period of time was known as the 'Green Revolution' and led Borlaug to win the Nobel Peace Prize because his work helped to alleviate hunger in developing countries.
Moreover, current agricultural biotechnology corporations use DNA recombinant technologies to develop genetically modified organisms, which exhibit desired traits for agriculture (for example, resistance to drought or high grain yield).
A genetically modified organism is any organism (e.g., a plant) whose genetic material has been altered by using DNA recombinant technologies.
