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.
Answer: -Some (but not all) plant cells - mostly those in the middle of leaves - have chloroplasts - green structures which contain the pigment chlorophyll. This absorbs light energy which is then used in photosynthesis to make sugars.
