The second stage of integrated waste water treatment in Arcata

(1) 6 Marshlands of 60 hectares

(2) Appropriate plants, algae, fungi and bacteria were seeded into this marshland

(3) Such arrangements actually neutralize, absorb and assimilate the pollutants

(4) All of these

(1) A citizens group called Friends of Arcata Marsh, India

(2) Responsible for the upkeep and safeguarding of integrated waste water management project of Arcata

(3) Comes under Government of India

(4) All of these

(1) Sanctuary with a high level of biodiversity in the form of fishes, animals and birds

(2) Appropriate plants, algae, bacteria neutralize, absorb and assimilate the pollutants

(3) Both A and B

(4) Act as ecological sanitation

(1) Formed in lower atmosphere

(2) Formed in Troposphere

(3) Harms plants and animals but is not lethal

(4) All of these

(1) Found in the upper strata of the atmosphere

(2) Found in Stratosphere

(3) Acts as a shield to UV light

(4) All of these

(1) Because DNA and Protein preferentially refract UV light

(2) Because DNA and Protein preferentially radiate UV light in the form of heat energy

(3) Because DNA and Protein preferentially absorb UV light and as a result chemical bonds are broken

(4) Both B and C

(1) Ozone is formed by the action of UV rays on molecular Oxygen

(2) Ozone is degraded there

(3) There is a balance between formation and degradation of ozone

(4) There will be accumulation of Chlorofluorocarbons or CFCs which are acted upon by UV rays and protects the ozone layer.

(1) Release Cl atoms in stratosphere

(2) Used as refrigerant

(3) Cl of CFCs degrade ozone releasing molecular oxygen

(4) Cl atoms released out of CFCs are also used up during degradation of Ozone

(1) Due to no formation of Ozone

(2) Due to high formation and low degradation of ozone

(3) Due to low formation and high degradation of ozone

(4) Due to no degradation of ozone

(1) Damages DNA and causes mutation

(2) Ageing of skin and damage to the skin cells and cause various types of skin cancer

(3) Inflammation of cornea, cataract

(4) All of these
