Answer: Nitrogen bases
Explanation: because of the base pair rules
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.
Many owls eat small rodents and similar critters. So let's say the rabbit population might grow if owls weren't there to keep the numbers down.
<span>Foxes probably eat the same sort of small rodents. So if owls weren't there, foxes would have more food to themselves, so their population might go up. </span>
<span>And if foxes had more small rodents to eat, they would eat relatively less of any one species. So if they had plenty of rabbits to eat, they might eat less squirrels, so the squirrel population would go up.</span>
