How old is Darren? we need to know his age before we answer
Answer:
Water pollution is one of the most common type of pollution that leads to the deterioration of the water quality mainly due to the man-made interference. Direct and indirect pollution are two of its types. Direct pollution as the term suggests refers to the direct flow of pollutants in the water in contrast to the indirect pollution that accounts for the transport of pollutants eventually to the water body.
Explanation:
Direct pollution is characterized by the release of toxic fluid directly in the water body. The main source of this type of pollution are the toxic pollutants from the large factories. Some of the other sources includes solid waste from the household activities and waste from agricultural practice like fertilizers, and the waste generated by the waste water treatment plant.

Answer:
c. 0.026
Explanation:
Suppose the population is in Hardy-Weinberg equilibrium. According to it,
p + q = 1
p² + 2pq + q² = 1
where p= frequency of dominant allele
q = frequency of recessive allele
p² = frequency of homozygous dominant genotype
q² = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype
Here, q = w = 0.84
p = W = 1 -w = 1- 0.84= 0.16
W² = 0.16 * 0.16 = 0.0256 = 0.026
Hence, frequency of the homozygous dominant genotype = 0.026
