3. Question
Biological Oxygen Demand (BOD) is a standard criterion for [2017]
CorrectThe amount of oxygen required by bacteria to break down the organic matter present in a certain volume of a sample of water, is called Biochemical Oxygen Demand (BOD). The amount of BOD in the water is a measure of the amount of organic material in the water, in terms of how much oxygen will be required to break it down biologically. Clean water would have BOD value of less than 5 ppm whereas highly polluted water could have a BOD value of 17 ppm or more.

4. Question
In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique? [2017]
1. It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature.
2. Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using micro-organisms.
3. Genetic engineering can be used to create microorganisms specifically designed for bioremediation.
Select the correct answer using the code given below:CorrectBiosparging is an in-Situ Bioremediation techniques in which we inject the air under pressure below the water table to enhance the rate of biological degradation of contaminants by naturally occurring bacteria. Hence statement 1 is right. In Google Scholar search engine is filled with academic papers on genetic engineering approaches to bioremediation. Hence 3 is also right. But not all compounds are susceptible to rapid and complete biodegradation, and bioremediation often takes longer time than other treatment processes. So, second statement unlikely to be correct. Hence, answer “C” 1 and 3 only.

6. Question
It is possible to produce algae based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry? [2017]
1. Production of algae based biofuels is possible in seas only and not on continents.
2. Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is completed.
3. Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns.
Select the correct answer using the code given below:CorrectUS National Research Council report on Algal Biofuel (2012) observed that
1. algae and cyanobacteria biomass production in the U.S. desert Southwest could be perceived as a good use of low-value land by some, but as an intrusion into pristine land by others. Similarly, the use of genetically modified organisms in production systems could affect social acceptability. So this is social concern. [and it also proves statement #1 wrong.]
2. Open Algal ponds will attract insect larvae invasion and affect predator-prey balance. This is ecological concern. Hence Statement 3 is right.
3. And the report discussed challenges production and technology. Hence answer 2 and 3.IncorrectUS National Research Council report on Algal Biofuel (2012) observed that
