Solutions

S1.Ans. (b)
Sol. Lysosomal membrane is formed in ER, later it is modified and transferred to the cis face of Golgi apparatus where further processing releases lysosome.

S2.Ans. (a)
Sol. pH of human blood is 7.4

S3.Ans. (b)
Sol. One of the secondary structures exhibited by DNA is the famous Watson–Crick model. This model says that DNA exists as a double helix. The two strands of polynucleotides are antiparallel i.e., run in the opposite direction.

S4.Ans. (d)
Sol. Methyl Isocyanate gas (MIC) is used in preparation of agricultural product pesticide, a posionous substance.

S5.Ans. (b)
Sol. The SI unit of acceleration is the metre per second squared (m s–2).

S6.Ans. (d)
Sol. Ice is less dense in comparison to liquid water. Actually when water freezes, water (H2O) molecules form a crystalline structure by Hydrogen bonds. These bonds cause molecules to push apart lowering the density of water (H2O).

S7.Ans. (c)
Sol. Nuclear potential and chemical energies implies the stored form of energy. But electrical energy is not a form of stored energy.

S8.Ans. (c)
Sol. The flavour of apples is mainly due to the ethanol (C2H5OH).

S9.Ans. (d)
Sol. Nail varnish remover generally contains acetone (CH3COCH3).

S10.Ans. (b)
Sol. The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.
