The answer is D yayayayay
The correct answer is Agronomy!
Agronomy is the science of producing food(crops), and this includes such aspects as the quality of the soil and the genetics of the plants. The reason why people are interested in it is that they want to maximize (improve) their food production!

Weathering is a natural process by which the surface mineral of rocks is carried away by various agents .The agents can be water,wind,and ice. weathering means disintegration of rocks and the small parts are being carried away by these agents and are found on different places.Weathering of rocks depends on the many factors such as climatic conditions,type of rock,water availability and many more.The small rocks mix with soil and helps form sediment .This sedimentation helps to shape the earth's surface.This is an important part of rock cycle and is very important.
Answer:
B) For a gene under negative repressible control, a small molecule is required to prevent the gene's repressor from binding to DNA.
Explanation:
Operon is usually present in prokaryotes. It has a group of genes being transcribed under the same promoter. So the genes are expressed together when required. An operon can be under negative or positive control. It can further be inducible or repressible.
Under negative repressible control the operon is normally in working condition. Repressor protein is present but unable to bind to the operator. When a corepressor binds to repressor, it is activated and finally binds to the operator halting the transcription process. Hence the small molecule (corepressor) leads to binding of repressor to DNA and not the other way round. A small molecule is required to prevent the gene's repressor from binding to DNA in case of negative inducible operon.
