Answer:
Option (C)
Explanation:
In no-till farming method, the farmer usually uses a no-till planter with the help of which they make a narrow type of trench that is sufficient enough for the seed to be grown in rows. The residue of the cover crop is allowed to place on the surface of the soil by not plowing, as a result of which the soil is protected from getting eroded and losing of moisture content. This improves soil quality.
This method helps in increasing the water content that percolates down into the soil, holding the organic matter and recycling of nutrient matters. It also expands the growth and population of microbes in the soil, which provides more nutrients to the soil and increases the fertility of the soil.
Thus, when a farmer leaves plant stalks in the field to reduce soil erosion, then it is known as no-till farming.
Hence, the correct answer is option (C).
The hole is a separate phenomenon because it correlates something other than global warming. it doesn’t focus on global warming but more on specific areas.
The rate would increase because more molecules would collide at the activation energy, which will cause more molecules to react, and thus it will speed up the reaction rate.
Answer:
binding of the hormone molecule with its receptor of the cell.
Explanation:
Hormones are chemical messengers secreted or released by endocrine glands to effect a response in another location called target location. Hormones are proteinous molecules and like every other protein, its function is determined by its shape.
Hormones function or effect their changes by binding to the receptor of the target cell. The hormone recognizes and will only bind to its own receptor molecule on its target cell on order to bring about any change. This defines the specificity of the hormone.
Extraction of aluminium metal takes place in three main stages¿mining of bauxite ore, refining the ore to recover alumina and smelting alumina to produce aluminium. Bauxite is mined by surface methods (open-cut mining) in which the topsoil and overburden are removed by bulldozers and scrapers.
