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:
The correct answer is option c.
Explanation:
In the 1990’s Ireland made unemployment benefits less generous. This provided an incentive to workers to find a job quicker as the employment benefits were reduced.
This would further cause the frictional unemployment rate to decline.
Frictional unemployment is the unemployment caused because of shifting from one job to another.
The natural rate of unemployment includes both structural unemployment and frictional unemployment. A reduction in frictional unemployment will cause natural unemployment to decrease.
Answer:
The Human Development Index, also knows as HDI, is a tool that was created by the United Nations to calculate and rank other countries tiers of social and economic aftereffect.
<span>Korea had been under Japanese domination since 1910, and had been very isolationist for most of the centuries before then. During the Japanese occupation, Japan tried to eliminate Korea as a separate country - suppressing their local government and their language, forcing Koreans to take Japanese names, destroying or stealing hundreds of cultural artifacts. When Japan surrendered in 1945 it was forced to give up conquered territories, including Korea.
Hundreds of thousands of Koreans died during WWII, as forced laborers and conscripted soldiers. Perhaps as many as 100,000 Korean girls and women were forced into sexual slavery as "comfort women". By the end of the war, more than 800,000 Japanese colonists were occupying Korea, though the majority of those returned to Japan after the surrender.
When Soviet Russia entered the war against Japan in the few days before Japan surrendered, it claimed the right to occupy some Japanese territories during the transition period to what was supposed to be home rule for former Japanese conquests. Between 1945 and 1948, while the United Nations was trying to help the Koreans set up an independent government, the Soviet Russians were working hard in their occupation zone to set up a communist government in their own image - this led to two Koreas, North and South, which led to the Korean War and the current stalemate between the two Koreas. The partition of Korea into North and South is a direct result of the end of World War II.</span>
