Solutions

S1.Ans. (c)
Sol. Newton’s 2nd Law – The rate of Change of momentum always acts in the direction of resultant force acting on a body = (F = ma) (where m = mass; a = aceeleration)

S2.Ans. (c)
Sol. Proline is an a-amino acid, one of the twenty DNA– encoded amino acids. L–Proline is an osmoprotectant and therefore is used in many pharmaceutical, biotechnological applications.

S3.Ans. (a)
Sol. The replication of DNA is a pre-requisite for a eukaryotic cell to undergo division. During the cell cycle, the DNA replicates in S phase (synthesis phase).

S4.Ans. (c)
Sol. The flavour of apples is mainly due to the ethanol (C2H5OH).

S5.Ans. (d)
Sol. Nail varnish remover generally contains acetone (CH3COCH3).

S6.Ans. (c)
Sol. The level of water in the pond remains unchanged.

S7.Ans. (d)
Sol. Counting the annual rings in horizontal cross section of a tree is a measure of its age. This study comes under dendrochronology.

S8. 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).

S9. Ans. (d)
Sol. Auxin is the plant hormone and is responsible for root formation. Adrenaline, Insulin and Oxytocin are animal hormones.

S10.Ans. (a)
Sol. Retina of the eye is comparable to the film of a traditional camera. Retina is a film of nerve fibres. Image of the object is formed at retina just like camera film is used to see the images.
