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.

What is cellphone communication?</u></h3>
- Mobile communication refers to the application of technology that enables remote communication without the need for a physical connection (wires or cables).
- Our lives are made simpler by mobile communication, which also saves time and effort.
- A mobile phone, often known as a cell phone, hand phone, or mobile cellular network, is one type of mobile communication (wireless communication).
- It is an electric device that transmits and receives data across a cellular network of base stations known as a cell site using full duplex two-way radio. These are some characteristics of mobile communication:
Balanced high capacity loads: High capacity load balancing must be incorporated into any wired or wireless infrastructure. New wireless devices are becoming increasingly more popular every day.
