<h2>Ultraviolet (UV) Light</h2>

Explanation:

  • <em>Ultraviolet germicidal irradiation (UVGI)</em> is a purification technique that  inactivate microorganisms and the short wavelength ultraviolet (UV-C) light to execute by destroying nucleic acids and upsetting their DNA, leaving them incapable to vital cellular functions.
  • <em>Ultraviolet (UV) light kills cells damaging their DNA</em>
  • <em>The subsequent thymine dimer is very stable,</em> however fix of this sort of DNA harm for the most part by extracting or expelling the two bases and filling in the holes with new nucleotides is fairly efficient.
  • UV light applies its mutagenic impact by energizing <em>electrons in atoms</em>
  • <em>The excitation of electrons in DNA atoms regularly brings about the development of extra bonds between contiguous pyrimidines (explicitly thymine) in DNA</em>

answer 1:

Environmental Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal, and light

Air Pollution

Water Pollution

Soil pollution

Noise pollution

Radioactive pollution

Light pollution

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil

Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.

Effects:

Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes.

answer 2:

The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

anwer 3:

advantages are

1_A Fuel Supply That Never Runs Out

2_Zero Carbon Emissions

3_Cleaner Air and Water

4_A Cheaper Form of Electricity

5_Renewable Energy Creates New Jobs

disadvantages are

1_Higher Capital Costs

2_Electricity Production Can Be Unreliable

3_Energy Storage Is a Challenge

4_It’s Impacted by Environmental Conditions

5_Renewables Still Have a Carbon Footprint

anwer 4:

Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.

answer 5:

You could do this by:

1_Try to stay away from disposable goods. In particular, paper plates, cups, bottles, and plastic utensils.

2_Buy durable and reusable goods. ...

3_Pack your lunch in a reusable box rather than foil or cling film.

4_Buying products with less packaging. ...

5_Buying products in bulk.

I WISH THIS WILL BE HELPFUL, GOOD LUCK :)
