Bring everything to Instructorl Bring Your Test Paper And The 2 Answer Sheets To The InstructorExplanation / Answer
1) The Biomagnification can be defined as it is the build up of the toxins in a food chain and the food web. the pesticide which is sprayed to control the mosquitoes in the region of the water bodies is absorbed by the cells of the microscopic creatures like phytoplantons and the zooplanktones. this means the highest concerntration will be found in the millions of the microscopic creatures at the first stage of the absorption and the transportation in the food chains.
so the correct answer is a).
----------------------------------------------------------------------------
2) Clivus multrum can be defined as it is a self contained composite toilet which uses the water less and the odour less toilet and the senitary system in this. this means that the toilet will not use the water to flush and there will be no requirement of the electricity.
so the correct answer is c)
-------------------------------------------------------------------------------
3) Salt water intrusion can be defined as it is the movement of the saline water into the fresh water aquifierswhich can lead to the contamination of the drinking water present at the base of the ground water table. it is mostly occurs in the coastal region aquifiers. thus the
correct answer is option c).
--------------------------------------------------------------------------------
4) The people of japan suffers from the dieases like retardation and the crippling in the locality of the region of the minamata way. this was termed as the minamata disease which was occurs due to the excessive poisoning of the severe mercury in the region and the water bodies. this make the people suffer from this disease.
so the correct answer is a).
--------------------------------------------------------------------------
5) Malaria is a type of disease which was plasmodium parasite. it is a life threatening mosquito born blood disease which was caused by this parasite. when the mosquito bites, this parasite enter in the body by the blood streams and veins and transfer to the all locations and developed the reproduction of the parasite further in the patients body. thus it sprayed by mosquito.
so the correct answer is c)
-------------------------------------------------------------------------
6) An oligotropic body of water can be defined as it is a type of water body which is having a higher dissolved oxygen in the deeper parts of the lake and have the abundant number of the organism in this. there is a lack of nutrients and thus make the improper growth of the creatures.
thus the correct answer is a) which is false.
----------------------------------------------------------------------------
7) grey water can be defined as it is the water which is formed by the household activities. it is a type of waste water which is generate in the house and building purposes like washing clothes, utensile, toilets etc. thus it can be reused in car wash floor wash and toilets purpose but being a waste water so it cannot be used to drink.
so the correct answer is d).
-------------------------------------------------------------------------
8) The nitrate can be there in the running water bodies as it can create the poisining of the water bodies when it goes to mix with the rivers and all. so the correct answer is c).
--------------------------------------------------------------------------
9) The aquifiers from which the water is draws by the long island is the upper glacial.
so the correct answer is d).
---------------------------------------------------------------------------
10) PCBs Dioxine and the DDT are the type of the pollutant which are termed as the sophisticated inorganics. as these are the inorganic compounds which are formed artifitially in the industries and when these are exposed to the water bodies, acts as a pollutant and toxics.
thus the correct answer is e)
