During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!

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.
