Solutions

S1.Ans. (b)
Sol. The site of cellular respiration is mitochondrion as it involved in generation of energy, (ATP). Nucleus consists of genetic material which is transferred from one generation to another, ribosome helps in protein synthesis and Golgi apparatus helps in glycosylation.

S2.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.

S3.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.

S4.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.

S5.Ans. (c)
Sol. Whether an object will float or sink in a liquid, depends on difference in the densities of the object and liquid.

S6.Ans. (a)
Sol. A ball balanced on a vertical rod is an example of unstable equilibrium.

S7.Ans. (d)
Sol. Tomato is red in colour due to the presence of lycopene pigment found in the chromoplasts.

S8.Ans. (d)
Sol. Psammophytes is a plant that grows in shifting sands, primarily in deserts. They are marked by a number of adaptations which enable them to exist on wind-blown sands for e.g. Haloxylon persicum, Calligonum, Ammondendron, Eremosparton, Smirnowi.

S9.Ans. (a)
Sol. A jet engine works on the principle of conservation of linear momentum. In jet engines, a large volume of gases produced by the combustion of fuel is allowed to escape through a jet in the backward direction. Due to the very high speed or velocity, the backward rushing gases have a very large momentum.

S10.Ans. (d)
Sol. Sodium metabisulphite (Na2S2O5) inhibits growth of bacteria and fungi including mold. It is an artificial food additive.
