Solutions
S1.Ans. (a)
Sol. In a three pin plug longest pin should be connected to ground terminal. Ground pin is the largest to supply the additional voltage that can give electric shock. And being the longest it can touch before live and neutral terminal.
S2.Ans. (a)
Sol. “Pakhui/ Pakke Tiger reserve” is in Arunanchal Pradesh, so if there is a wildlife sanctuary in Pakhui, it should be in “A” for Arunanchal Pradesh.
S3.Ans. (a)
Sol. Biodiversity is subject to many threats. The greatest is probably habitat destruction and fragmentation. But there are many other threats to biodiversity. Over-consumption by humans –by hunting, fishing, or collecting from the wild– threatens many species.
S4.Ans. (a)
Sol. Exposure of common salt to air is a physical change. In chemical sections, reactants produce substances which are different form the reactants No chemical realize taken plot when common salt (NaCl) is exposed to air as no new substances are produced.
S5.Ans. (b)
Sol. Oils are purified by steam distillation. In steam distillation process steam is bubbled through a heated mixture of raw material. Some of the target components will vaporize which are coded and condensed yielding a layer of oil and a layer of water.
S6.Ans. (b)
Sol. In situ conservation means conservation which takes place onsite. The major aim of this type of conservation is to preserve natural areas of the organisms and maintain their number.examplebiosphere, national park, sacred grooves etc.
S7.Ans. (c)
Sol. When air reaches the dew point at a particular pressure, the water vapour in the air is in equilibrium with liquid water which means that water vapour is condensing at the same rate at which liquid water is evaporating. Below dew point, liquid water will begin to condense.
S8.Ans. (c)
Sol. A person containing O+ blood group does not possess any antigen to elicit any antibody reaction in the acceptor. Thus, a person with O+ is the universal donor. AB+ on the other hand is a universal acceptor.
S9.Ans. (d)
Sol. Scattering of light takes place in colloidal solution. This phenomenon is called Tyndall effect. The path of the light beam illuminates by scattering of light.
S10. Ans. (d)
Sol. Telophase is the stage where cytokinesis usually occurs in animals, which means the cell divides into two daughter cells and is identical to each other.
