Solutions

S1.Ans. (b)
Sol. A long jumper runs before jumping to maintain momentum. This helps in jumping higher and longer because of inertia of motion gained due to the motion.

S2.Ans. (d)
Sol. Mirage is an optical illusion. The reason of mirage is total internal reflection of light. In summer air near the ground is hotter and hence rarer than the air above which is responsible for TIR, hence, mirage is formed.

S3.Ans. (b)
Sol. Wavelength is the distances between two points of the wave in the same phase. It is related to frequency and energy of the radiations. It helps in determining colour of light waves. The wavelength of light visible to eye falls between 400nm to 800nm.

S4.Ans. (d)
Sol. German silver is an alloy of copper (25-50%), zinc (25- 35%) and nickel (10-35%). It is used in utensils and resistance wire.

S5.Ans. (a)
Sol. Bullet-proof windows are constructed using several layers of polycarbonate and/or laminated glass

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.
