Answer:
Option-C
Explanation:
The flow of nutrients from the sewage and industries is the cause of the nutrient pollution in water bodies. These chemicals get accumulated in the water bodies affecting the aquatic ecosystem to a very large extent.
The increased level of nitrogen and phosphorus causes eutrophication which is also known as algal-boom. These nutrients cause the massive growth of algae which decreases the oxygen level of the water bodies. This increases BOD level of the water bodies which does not allow the growth of other aquatic species.
As a result of this, the dead zones are created where nothing can survive and therefore is the correct answer.
Thus, Option-C is the correct answer.
Cyclins regulate the cell cycle by binding to cyclin dependent kinases, forming a protein complex.
There are 23 pairs of chromosomes in each human cell and the autosomes (chromosome pairs 1-22) determine certain characteristics. However, there is still one more pair of chromosomes and these are called the sex chromosomes and they can either be shaped as XX or XY. The father's chromosome is the chromosome that determines whether it is a boy or girl, and there is an exact 50/50 chance of it being male or female you just need to draw a punnet square.
