Solutions

S1.Ans. (c)
Sol. Plastid is a double-membrane organelle found in plants, algae, and some other eukaryotic organisms. They are of different types such as chloroplasts, chromoplasts, gerontoplasts, & leucoplasts (used for storing starch and fats).

S2.Ans. (a)
Sol. The endoplasmic reticulum bearing ribosomes on their surface called rough endoplasmic reticlum (RER) which are actively involved in protein synthesis. The smooth endoplasmic retriculum (SER) is the major site for synthesis of lipid. In animal cells, steroidal hormones syntherized in SER.

S3.Ans. (a)
Sol. Mercury is very good conductor of heat as it is the only liquid metal. It is used in thermometer also.

S4.Ans. (d)
Sol. Air is filled in vehicle tyres because it is highly compressible.

S5.Ans. (c)
Sol. Heat given/taken by the substance is equal to the latent heat of fusion or vaporization of the substance. That is why the temperature of the substance remains the same during the change of state.

S6.Ans. (c)
Sol. An egg when placed in ordinary water sinks to the bottom as the density of egg is higher than the density of ordinary water. Density is the mass of a material per unit volume, thus, adding salt to water (brine) increases the density of solution because salt increases the mass without changing the volume. That is why, an egg when placed in brine would float.

S7.Ans. (c)
Sol. In the Aerobic respiration the complete oxidation of glucose takes place in mitochondria and energy is stored in the form of ATP. Mitochondria are also known as the power house of cell.

S8.Ans. (c)
Sol. The level of water in the pond remains unchanged.

S9.Ans. (b)
Sol. Proteins are polypeptides. They are linear chains of amino acids linked by peptide bonds.

S10.Ans. (a)
Sol. When two ice blocks are pressed together, little heat is generated due to pressure and of friction, which just melts the outer layer. When that melts, friction decreases and due to the low temperature of both the ice cubes, the water just refreezes.
