S5.Ans. (d)
Sol. Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids. This is the principle behind liquid-in-glass thermometers.

S6.Ans. (b)
Sol. Fundamental physical quantities that do not depend upon other physical quantities. There are seven fundamental quantities- length, mass, temperature, time, electric current, luminous intensity and amount of substance.

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. (b)
Sol. A spreadsheet is an interactive computer application for organization, analysis and storage of data in tabular form. Spreadsheets are developed as computerized simulations of paper accounting worksheets. The program operates on data entered in cells of a table.
