Solutions
S1.Ans. (c)
Sol. A balanced diet is a diet which provides sufficient amount of carbohydrates, fats, proteins, vitamins and minerals nutrients to maintain good health and with a small provision for periods of leanness or scarcity.
S2.Ans. (d)
Sol. Urochrome is the chemical which is responsible for the yellow colour of urine. Bile is a yellowish to dark green fluid produced by the liver of most vertebrates that helps in the digestion of lipids and fats in the small intestine. Lymph is the fluid that circulates throughout the lymphatic system; it is found in the interstices of the body tissues.
S3.Ans. (b)
Sol. The SA node is called as the natural pacemaker of the heart. It is comprised of a cluster of cells that are situated in the upper part of the wall of the right atrium. It is called us the pacemaker as the electrical impulses are generated here.
S4.Ans. (a)
Sol. Animals release certain types of sex pheromones for the purpose of mating during the breeding season to attract the opposite sex.
S5.Ans. (a)
Sol. The water will freeze because on Moon the temperature is below the freezing point i.e., very low.
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.
