Q. Consider the following statement 1. Kolleru Lake is located between Krishna and Godavari deltas. 2. It was designated wetland of international importance in November 2002 under Ramsar Convention. Choose the correct code a) 1 only b) 2 only c) Both d) none
Answer: C Explanation: Kolleru Lake is one of the largest freshwater lakes in India It was declared as wildlife sanctuary in November 1999 under located in Andhra Pradesh Wildlife Protection Act of 1972, and designated wetland of international importance in November 2002 under Ramsar Convention. It is important habitat for resident and migratory birds like pelican bird. The 'Pelican Bird Festival-2018' was held for first in Atapaka Bird Sanctuary on at Kolleru lake in Andhra Pradesh.
ASH TRACK app: It is a Web based monitoring System and a Fly Ash mobile application for better management of fly ash produced by thermal power plants. Launched by Ministry of Power. Fly ash is end product of combustion during process of power generation in the coal based thermal power plants. It will allow user to select power station from where he wants to take fly ash. It will also show ash availability, distance from user's location It will allow effective monitoring and reviewing for increasing fly ash utilization. It will help in protecting environment in terms of reduction in fugitive emissions, saving of precious top soil and conservation of land for sustainable development.
Q. The relationship between individuals of two species of which one is benefitted and the other is almost unaffected is a) mutualism b) commensalism c) ammensalism d) none
Answer: b Explanation: Mutualism is an association between individuals of two species, both of which are benefitted but cannot live separately under natural conditions e.g. instances of mutualism exist between animals and plants and also in between plants e.g. lichens. Ammensalism is an interaction in which one species causes harm to another spices with its toxic secretion often without gaining any benefit from the interaction. Commensalism is the relationship between individuals of two species of which one is benefitted and the other is almost unaffected i.e.; neither benefitted nor harmed
Q. Major aerosol pollutant in jet plane emission is a) Sulphur dioxide. b) Carbon monoxide c) Flurocarbon d) Methane
Answer: C Explanation: Aerosols are minute particles suspended in the atmosphere. Aerosols are short-lived, unlike greenhouse gases that persist and accumulate in the atmosphere for longer period. Inaddition to scattering orabsorbing radiation, aerosols can alter the reflectivity, or albedo, of the planet. .In the Arctic, aerosols from wildfires and industrial pollution are likely hasteningthe melting of ice. also lead to the destruction of stratospheric ozone. Main source of aerosols is the emission of jet planes, where fluorocarbons are used. These chlorofluorocarbons deplete the ozone layer in the higher atmosphere Note: recent study revealed that higher aerosol loading can enhance the strength of convective rainfall and increase the frequency and intensity of extreme rainfall during Indian summer monsoon
Q. Homeostasis is? a) b) c) Tendency of biological systems to resist change. disturbance of self regulatory system and natural controls. regulation of the internal environment to maintain a constant state life-sustaining chemical transformations within the cells of living organisms d)
