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. (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.

S5. 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.

S6. Ans. (d)
Sol. The Golgi complex and rough ER work closely. When a protein is made in the ER, then transition vesicles are synthesized. These vesicles float through the cytoplasm to the Golgi apparatus and are absorbed. After the Golgi does its work on the molecules inside the sac or the vesicle a secretory vesicle is created and released into the cytoplasm. So the main function of the Golgi bodies is secretion.

S7.Ans. (b)
Sol. Lightning can even burn a tree because it contains tremendous amount of electric energy.

S8.Ans. (b)
Sol. Magnesium comes in secondary nutrients, not in micronutrient group.

S9.Ans. (b)
Sol. Geostationary satellite orbits the earth directly over the equator. At geosynchronous orbit, the orbital period of the satellite matches the orbit of the Earth that is 24 hours.

S10.Ans. (c)
Sol. When a hard boiled egg after shelling is immersed in saturated brine, its size remains same. Due to coagulation of inner liquid there is no flow of solvent molecules across the membrane.
