(e) All of the above


S1.Ans. (b)
Sol. Nettle leaves are rich in vitamins A and C, potassium, manganese etc. The Accidental touch of nettle leaves creates a burning sensation because it injects formic acid (also called called methanoic acid), acetylcholine and histamine when it comes in contact.

S2.Ans. (a)
Sol. The energy released from the collapse of the gas into a star causes the centre of the star to become extremely hot. When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy. The fusion reaction is a very efficient process, releasing a huge amount of energy. This is because a single helium atom contains less mass than two hydrogen atoms. The excess mass is released as energy.

S3.Ans. (d)
Sol. Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. Cells within the meristematic tissues are selfrenewing, so that each time they divide, one cell remains identical to the parent while the other can specialize and become part of another plant structure. The meristematic tissue is therefore self-sustaining.

S4.Ans. (d)
Sol. When CO is not ventilated it binds to haemoglobin, which is the principal oxygen-carrying compound in blood; this produces a compound known as carboxyhaemoglobin. Carbon monoxide toxicity arises from the formation of carboxyhaemoglobin, which decreases the oxygen-carrying capacity of the blood and inhibits the transport, delivery, and utilization of oxygen by the body.

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. 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.

S7.Ans. (a)
Sol. As the cat falls from a height, it bends the legs to absorb the impact of falling and immediately adjust itself.

S8.Ans. (d)
Sol. g – rays has highest frequency range and hence highest penetrating power. These are able to travel many feet in air and many inches in human tissue. These readily penetrate most materials and are sometimes called “penetrating” radiation.

S9.Ans. (b)
Sol. The credit of construction of first nuclear reactor goes to Fermi. On December 2, 1942 Fermi reported having produced the first self sustaining chain reaction.

S10.Ans. (a)
Sol. Atomic bomb is a nuclear bomb that involves nuclear fission reactions. The most common isotopes and for fissile reactions are uranium (U – 235) and plutonium (P – 239). So in the event of an atomic bomb explosion, the most likely element that would enter the food chain is U – 235, among the options.
