Question 1 of 5
1. Question
2 points
Consider the following statement in context of speciation:
1.Theory of natural selection is responsible for speciation.
2.Geographical barrier is a way of speciation.
3.The species evolved due to speciation is capable of interbreeding with parent species.
Which of the statements above is/are correct?
Correct
Correct Answer: A
Explanation
• Option A is correct.
• Speciation is the process by which new species are formed and evolution is the mechanism by which speciation is brought about. Natural selection determines as to which variation will succeed and survive. Those variations that enable a species to survive in the struggle for existence are encouraged and promoted. Thus natural selection is responsible for speciation. Hence,statement 1 is correct.
• A species comprises many populations. Often different populations of a species remain isolated due to some geographic barrier such as mountain, ocean, river, etc. Geographic isolation occurs when a physical barrier develops between two populations of a species. The most common way a population undergoes speciation is by geographic isolation. Hence, statement 2 is correct.
• The population then becomes separated into two completely isolated populations by a barrier which prevents their interbreeding and gene exchange. Hence the new species become completely different from parent species and are unable to interbreed with parent species too. Hence, statement 3 is incorrect.

Which of the following is/are characteristic of Oligotrophic lakes?
1. High plant and animal species diversity
2. Oxygen in bottom layers are absent
3. Highly nutrient rich water
Select the correct answer using the code given below.
Correct
Correct Answer: A
Explanation
• Option A is correct.
• There are many plants and animal species in Oligotrophic lakes. Thus Oligotrophic lakes are rich in diversity.Hence,statement 1 is correct.
• Oxygen is present in the hypolimnion (bottom layer) of Oligotrophic lakes as the sunlight reaches to the bottom of the lake for plants to perform photosynthesis. Hence statement 2 is incorrect.
• On the basis of their nutrient content, they are categorized as Oligotrophic (very low nutrients), Mesotrophic (moderate nutrients) and Eutrophic (highly nutrient rich). Hence statement 3 is incorrect.

Which is the following is/are characteristic of Mangrove plantation?
1. Spongy, aerial roots that grow out of the water and into the air.
2. Leaves are thin and contain salt absorbing glands.
3. Seeds germinate in the tree itself.
Select the correct answer using the code given below.
Correct
Correct Answer: C
Explanation
• Option C is correct
• Mangroves are the characteristic littoral plant formation of tropical and subtropical sheltered coastlines. Mangroves are trees and bushes growing below the high water level of spring tides which exhibits remarkable capacity for salt water tolerance. It produces pneumatophores (blind roots) to overcome respiratory problems in the anaerobic soil conditions. Mangroves send vertical “Pneumatophores” or air roots up from the mud. Hence, statement 1 is correct.
• Some secrete excess salt through their leaves as if you look closely, you can see crystals of salt on the back of the leaves; others block absorption of salt at their roots. Leaves are thick and contain salt secreting glands. Hence, statement 2 is incorrect.
• Mangroves exhibit Viviparity mode of reproduction i.e. seeds germinate in the tree itself (before falling to the ground). This is an adaptive mechanism to overcome the problem of germination in saline water.Hence,statement 3 is correct.

Consider the following statement in context of Pradhan Mantri JI-VAN Yojana:
1. It aims for improving farmer income by providing them remunerative income from their forest based traditional & indigenous medicinal knowledge system.
2. It will help in Improving farmer income by providing them remunerative income for agriculture residue.
3. The main objective of this scheme is to protect forest areas from human encroachment.
Which of the statements given above is/are correct?
Correct
Correct Answer: A
Explanation
• Option A is correct, Only statement 2 is correct. Statements 1 and 3 are incorrect.
• Minister of State for Petroleum and Natural Gas is nodal ministry for Pradhan Mantri JI-VAN (Jaiv Indhan- Vatavaran Anukool fasal awashesh Nivaran) Yojana.
• The main objective of this scheme is to provide financial support to integrated bio-ethanol projects for setting up Second Generation (2G) ethanol projects in the country using lignocellulosic biomass and other renewable feedstock. Hence, statement 3 is incorrect.
• Some other objectives of scheme are:
1) Improving farmer income by providing them remunerative income for their otherwise waste agriculture residues. (Hence, statement 2 is correct while statement 1 is incorrect)
2) Creating rural & urban employment opportunities in 2G Ethanol projects and Biomass supply chain
3) Contributing to Swacch Bharat Mission by supporting the aggregation of non food biofuel feedstocks such as waste biomass and urban waste
4) Indigenizing of Second Generation Biomass to Ethanol technologies
5) The ethanol produced by the scheme beneficiaries will be mandatorily supplied to Oil Marketing Companies (OMCs) to further enhance the blending percentage under EBP Programme.

In the context of environment and ecology, what is common between Shannon Index, Simpson Index, and Berger Parker Index?
a) It is the measure of progress made in achieving sustainable development goals
b) It is a measure of the share of renewable energy in the total energy basket.
c) It reflects the extent of depletion of the Ozone layer.
d) It is used to calculate the biodiversity in a country.
Correct
Correct Answer: D
Explanation
• Option D is correct
• Shannon Index, Simpson Index, and Berger Parker Index are measures of biodiversity in a country. • These index are quantitative measure that reflects how many different types (such as species) there are in a dataset (a community), and that can simultaneously take into account the phylogenetic relations among the individuals distributed among those types, such as richness, divergence or evenness.These indices are statistical representations of biodiversity in different aspects (richness, evenness, and dominance).
