NCERT Class 11: India- Physical Geography

7)Consider the following statements in respect of Trade Related Analysis of Fauna and Flora in Commerce (TRAFFIC):

2. The mission of TRAFFIC is to ensure that trade in wild plants and animals is not a threat to the conservation of nature.
Which of the above statements is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2

8)Due to some reasons, if there is a huge fall in the population of species of butterflies, what could be its likely consequence/consequences?
1. Pollination of some plants could be adversely affected.
2. There could be a drastic increase in the fungal infections of some cultivated plants.
3. It could lead to a fall in the population of some species of wasps, spiders and birds.
Select the correct answer using the code given below:
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

Statement 1 is right (by common knowledge) but for the sake of reference- NCERT Class 12 biology page 30! This eliminates “B”.
Second statement should be wrong because of the extreme word “drastic“. This eliminates “D”. Besides I’m unable to find any specific reference that mentions linkage between butterfly population vs fungus infection.
Birds and spiders tend to prey on butterflies (by common knowledge) but again for sake of reference: this google book, so statement 3 is a possible outcome.
Hence answer “C”: 1 and 3 only.

9)Biological Oxygen Demand (BOD) is a standard criterion for
(a) Measuring oxygen levels in blood
(b) Computing oxygen levels in forest ecosystems
(c) Pollution assay in aquatic ecosystems
(d) Assessing oxygen levels in high altitude regions

NCERT Class 11 Chemistry: Ch. 14-Environmental Chemistry, page 407

10)In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique?

It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature.Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using microorganisms.Genetic engineering can be used to create microorganisms specifically designed for bioremediation.

Select the correct answer using the code given below:
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

11)In the context of mitigating the impending global warming due to anthropogenic emissions of carbon dioxide, which of the following can be the potential sites for carbon sequestration?
1. Abandoned and uneconomic coal seams
2. Depleted oil and gas reservoirs

Select the correct answer using the code given below:
(a) 1 and 2 only
(b) 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

12) It is possible to produce algae based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry?

Production of algae based biofuels is possible in seas only and not on continents.Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is completed.Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns.
