S1.Ans. (d)
Sol. Argon (Ar) is abundantly found in atmosphere. It makes up 0.9 percent of the atmosphere.

S2.Ans. (d)
Sol. Mitochondria contain DNA other than nucleus. Mitochondria are thought to be the parasites in the eukaryotic cells that got inside the latter as a result of the endo-symbiotic event that took place earlier in the evolution. Centriole is a small set of microtubules, Golgi apparatus is a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.

S3.Ans. (b)
Sol. Electric bulbs are generally filled with argon gas because this gas is able to burn very intensely and produce bright light.

S4.Ans. (b)
Sol. Myopic eye can see near objects clearly but cannot see far objects clearly.

S5.Ans. (a)
Sol. A swimming pool looks shallower than it really is, when seen by a person standing outside near it, because of the phenomenon of refraction of light.

S6.Ans. (b)
Sol. Virus is not a cell; it remains just in the form of a genetic material or encapsulated on outside with a protein capsid. It generally injects its genetic material into the host cells wherein the viral proteins get synthesised.

S7.Ans. (b)
Sol. Ferns, a group under pteridophytes have large number of chromosomes e.g. Ophioglossum reticulatum has 2n=1260, highest known in all life forms.

S8.Ans. (a)
Sol. As a certain impulse applied for a short time will give a large force so the chinaware breaks into pieces. Therefore, chinaware is wrapped in straw of paper while packing so that the event of fall (impact) will take a longer time to reach the chinaware through straw of paper and hence the average force exerted on the chinaware is small and chances of its breaking reduce.

S9.Ans. (d)
Sol. For both stationary and moving objects with unchanging speed and direction, all the forces acting on the objects are in balance with each other, i.e. they all cancel each other.

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.
