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.

George Fredrick Handel composed his messiah during three weeks of intense, creative energy. Many believe Handel suffered a mild form of bipolar disorder.

Extreme mood swings, including emotional highs (mania or hypomania) and lows, are a symptom of bipolar disorder, formerly known as manic depression (depression).

When you experience depression, you could feel sad or hopeless and stop enjoying or being interested in most activities. You might experience mania or hypomania (a less severe form of mania), which can make you feel euphoric, energized, or excessively irritable. The ability to think clearly, energy levels, activities, judgment, and behavior can all be impacted by these mood changes.

Mood swing episodes can happen infrequently or repeatedly each year. While the majority of people will have some emotional symptoms in between bouts, some people might not.

Although bipolar disorder is a lifelong diagnosis, by adhering to a treatment plan, you can control your mood swings and other symptoms. The majority of the time, psychotherapy and drugs are used to treat bipolar disorder (psychotherapy).
