(c) Methane
(d) Carbon dioxide
(e) None of the above

Solutions

S1.Ans. (d)
Sol. Colloids are a mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. The substances are present as larger particles than those found in solution, but are too small to be seen with a microscope.

S2.Ans. (d)
Sol. Methyl Isocyanate gas (MIC) is used in preparation of agricultural product pesticide, a posionous substance.

S3.Ans. (d)
Sol. Nail varnish remover generally contains acetone (CH3COCH3).

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

S5.Ans. (c)
Sol. The smooth muscle fibres taper at both ends (fusiform) and do not show striations. Cell junctions hold them together and they are bundled together in a connective tissue sheath. The wall of internal organs such as the blood vessels, stomach and intestine contain this type of muscle tissue.

S6.Ans. (c)
Sol. Bacteria are considered more as plants than animals because of the presence of cell wall. The cell wall is composed of peptidoglycan.

S7.Ans. (d)
Sol. All single – celled eukaryotes are placed under Protista. This kingdom forms a link with others dealing with plants, animals and fungi.

S8.Ans. (c)
Sol. Pure water is neutral in nature hence, the pH value of pure water is 7.

S9.Ans. (a)
Sol. Acetylene is the nontoxic gases that help in formation of enzymes which riper fruit. Ripening is a process in fruits causes them to become more palatable.

S10.Ans. (a)
Sol. The pH of fresh ground water slightly decreases upon exposure to air because when it comes to air, it absorbs the carbon dioxide (CO2), and for carbonic acid (H2CO3) which is a weak acid i.e. less pH.
