How has technology been used to address issues to sewage

Biology
1 answer:
vfiekz [6]3 years ago
7 0
The answer is A, as most sewage treatment plants use bacteria to break down and remove nutrients. The main water pollution problem caused by sewage effluent is eutrophication, related to the release of nutrients into rivers and lakes. Nutrients such as nitrogen and phosphorus ions result in high algal growth. Some algal blooms release toxins, and algal blooms also disrupt the natural dissolved oxygen concentration cycles. Fish kills are often because eutrophication has resulted in anoxic conditions. 

Anyway, wastewater treatment plants utilise bacteria to facilitate nitrification or denitrification, which removes ammonia and nitrates/nitrites, respectively.

Between 1987 and 1996, the grey wolf population in the area affected by the Chernobyl disaster
Rainbow [258]

Given what we know, despite not having access to the graph mentioned in order to provide a detailed answer, we can make the estimated guess that the grey wolf population probably experienced the greatest growth in 1994.

<h3>Why is C the most appropriate answer?</h3>
  • The information given describes an increase in population during these years.
  • The increase is a 7 fold increase to that of the years prior to the disaster.
  • The options each list scenarios in which the population decreases, which is not consistent with the information provided.
  • Option C is the only non-decreasing option.

Therefore, given the information that during the years mentioned the population of wolves increased by seven times its number from before the disaster, we can confirm that since option C is the only option that does not describe a decrease in population, this must be the correct choice.

Explain how a significant increase in the use of wind energy would affect the energy supply of coal.
allsm [11]
<span>The increase in the use of wind energy does not have to affect the energy supply of coal, since they are not related in any way and do not depend on each other. It's totally out of logic. They are different energies, the wind energy should not affect the energetic consumption of coal for the simple fact that coal is not necessary to produce wind energy, but it could be said that the demand for coal could be reduced by a small percentage only If the wind energy is used much more.</span>
