Answer: The Prairies are known as the 'Granaries of the World' due to the huge surplus of wheat production. The soil here contains high humus content which provide required nutrition to the crops. The temperature in the Prairies is also suitable for the growth of food crops.
Explanation:
Answer:
The water quality is deteriorated as there is depletion in Oxygen O₂.
Yes, the activity of the yeast has precluded the usage of the water
Explanation:
Here, we note that the addition of more or fewer drops of Reagent D sodium hydroxide (NaOH) is required to get the same blue color as in Phase 1 where no yeast is added indicates the level of O₂ in the water as the amount of O₂ concentration in the solution is directly proportional to the amount of Reagent D required to reach blue, meaning the O₂ is depleted.
When less sodium hydroxide is required to turn blue we have depleted sodium hydroxide in the solution that is the yeast added in Phases 2 or 3 of the experiment, consume O₂
Eutrophication is the enrichment of a body of water with nutrients that results in a change in the ecosystem such as: algae production, oxygen depletion and other results that diminishes the water usage.
I am not really understanding your question.
It's shaped like an oval.
