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:
- Chemical factors;
The chemical factors like the salinity and the composition are very important for the formation of the soil, as well as for determining the type of soil.
- Physical factors;
The most important of the physical factors are the erosion and deposition. While the erosion removes layers of soil from a certain places, the deposition brings that material on another place and makes layers which set of a new start for soil formation on another place.
- Climatic factors;
The climate is extremely important because it sets the basic for the soil formation. Different types of climate result in different types of soil, and the fact that the climate is the factor that enables certain plants to grow in certain conditions, makes it possible for the soil to become richer or poorer depending on the biomass available.
Explanation:
The book was written as a criticism of slavery. With the passage of the Fugitive Slave Act in 1850, people in the north were required to return slaves to the south by law or they would be arrested. Uncle Tom's Cabin made people in the north feel badly for the terrible conditions of the slaves and not want to comply with the Fugitive Slave Act.
