Answer:
The correct answer is the letter D. Intensive rice cultivation
Explanation:
Subsistence agriculture is characterized by low technical level in small production units with the objective of directly feeding family members. Examples of low-intensity agricultural activities are carried out on small and medium-sized farms, usually with family labor. It occurs in low-valued areas, which do not interest commercial agriculture, however it is practiced worldwide.

Answer
Raise the concentrations of the reactants to see if activity can be restored through reactant competition with the inhibitor for binding at the active site.
Explanation:
Competitive inhibitors have a structure similar to that of the normal substrate. Like the substrate, the inhibitor binds temporarily to the enzyme's active site but is not converted to products. This way, the inhibitor competes with the normal substrate for binding onto the enzyme's active site.
Non-competitive inhibitors do not compete with the normal substrate for the active site. They bind at a site different from the active site in a way that alters the structure of the active site. The result is that the normal substrate fails to bind to the active site.
The cause of acquiring cancer does not only rely on genetics.

Answer:
Once nitrogen is converted into compounds like ammonium and nitrate, these can be taken up from soils by plants and then the nitrogen can be used to form macromolecules like proteins and nucleic acids (DNA and RNA). ... It is an important part of many cells and processes such as amino acids, proteins and even our DNA.
