Explanation:

GM CROP-GENETICALLY MODIEFIED CROPS

A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.[1] These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather.[2]

Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to evaluate optimality degrees and comfort ratio of greenhouses, such as air temperature, relative humidity and vapour-pressure deficit, in order to reduce production risk prior to cultivation of a specific crop.

Answer:

1  Genetically modified crops (GM crops) are crops which have had their DNA altered in a way that does not occur naturally.

b   In 2018, agriculture, forestry and fishing accounted for 14.68 percent of the country's GDP. ... Vietnam's main agricultural crops are rice, cassava, maize and sweet potatoes. The rice consumption in Vietnam reached 21.5 million metric tons, ranking it on fifth place after China, India, Indonesia and Bangladesh

Agriculture is the largest employment sector in Bangladesh. ... A plurality of Bangladeshis earn their living from agriculture. Although rice and jute are the primary crops, wheat is assuming greater importance. Tea is grown in the northeast.

2  A greenhouse (also known as a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.                                                                                                    b   Granular urea is chemically the same as prilled urea. Granular urea, however, is slightly larger and harder. Today, the use of prilled urea is more prevalent because it is more resistant to breaking down when being blended with the other components of fertiliser.
