Answer: d. migration away from productive growing areas
Explanation:
The rice, corn and wheat are the basic food crops. These crops are used for making several dishes their flour as well as the grains of rice and corn are eaten when cooked. These three crops are necessary to be grown on large scale to meet the basic food requirements of the large growing population worldwide. The plant roughage of these three crops can be used to make biofuels. These are used as a fodder crops to feed poultry and cattles for meat harvest.
The demand will also increase when one is migrated to an unproductive region. However, the increased demand is due to decreased supply and not because of increased consumption hence, it will not directly contribute to increase in demand of crops.

Answer:
When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.
Explanation:
A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.
The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.
An<u> </u><u>isotonic solution </u><u>does not generate gradients</u>, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.
