Solutions

S1.Ans. (c)
Sol. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.

S2. Ans. (b)
Sol. Diamonds have a very high refractive index (about 2.42 compared to about 1.5 for glass). The amount of light reflected at an air/other material interface is related to the refractive index charge at the interface and the bigger the refractive index change, the more light is reflected. Thus, diamond reflects large amount of light and therefore, sparkles more.

S3.Ans. (b)
Sol. Hydrogen bomb was discovered by the American scientist in 1952. It is based on the reaction of nuclear fusion. It is based on uncontrolled chain reaction.

S4.Ans. (b)
Sol. Convex mirror is a diverging mirror used as a rear view mirror in the vehicles as it covers wide range of vehicles coming behind.

S5.Ans. (c)
Sol. All noble gases are present in Earth’s atmosphere except for helium and radon. Noble gases are group of highly unreactive elements placed in the Gr-18 (VIIIB) in the periodic table.

S6.Ans. (c)
Sol. Distillation is used to separate mixtures of liquids by exploiting differences in the boiling points of the different components.

S7.Ans. (b)
Sol. Algae, bryophytes and pteridophytes are true plants and contain chlorophyll. While fungi have characteristics that put this kingdom more close to animals, one of the features is that all fungi are heterotrophs and contain no chlorophyll.

S8.Ans. (c)
Sol. Sclerenchyma tissues are found in hard parts of plant body, in cortex, pith, hypodermis, in the pulp of fruits. Young cells are living and they have protoplasm. But matured cells becomes dead due to deposition of secondary walls. They give mechanical support, strength and rigidity to the plant body.

S9.Ans. (d)
Sol. Pollination by snails or slugs is known as Malacophily, which is rare phenomenon. While entomophily is pollination by insects and chiropterophily is pollination by bats.

S10.Ans. (c)
Sol. Insulin is a kind of peptide hormone. It is secreted from the beta cells of the pancreas. It is the main hormone that regulates the glucose metabolism in humans.
