Which source creates the most direct pollution?

Otrada [13]

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.

A scientist wants to begin making a DNA fingerprint, but she has only a very small DNA sample. What should her next step be

azamat

For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.

Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-

1. Denaturation of the double-stranded DNA (at around 95°C)

2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)

3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).

With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.
