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.
B. by a charter hope this helps good luck
"I would give him a score of about 5 out of 10, which was a vast improvement over John Q. Adams and his cronies. If you were a poor, white male, he was your guy. He greatly democratized the process of elections in that era and was our first grassroots president. However, Jackson usually did what Jackson wanted to do, even if it meant alienating many of the people who got him elected. He did not side with Southerners during the nullification crisis and was prepared to use troops against South Carolina to enforce a law that most Southerners hated. He blatantly ignored John Marshall’s decision in Worcester v. Georgia, but an argument could be made here that he was acting in favor of democracy in this case, as most white Southerners probably wanted the Cherokee moved off of their land. He was a very complex and fascinating guy, but his critics called him King Andrew for a reason." -Robert Marshall
