Solutions
S1.Ans. (c)
Sol. The subcutaneous layer is the innermost layer of the skin. It consists of a network of fat and collagen cells and functions as both an insulator, conserving the body’s heat, and as a shock-absorber, protecting the inner organs.
S2.Ans. (c)
Sol. In plants, meiosis occurs in the reproductive cells like in anthers and Ovary. In anthers pollen grains are formed by meiosis and within the ovary to form ovules.
S3.Ans. (d)
Sol. Connective tissues are the most diverse and widely distributed tissues in the body. Bone, types of blood are well-known connective tissues which perform many different functions and constitute different properties. Collagen fibres, fibroblasts and other components form important constituent of connective tissues.
S4.Ans. (a)
Sol. A power loom is a mechanised loom powered by a line shaft, and was one of the key developments in the Industrial Revolution. Edmund Cartwright the powerloom which revolutionaries the textile industry.
S5.Ans. (c)
Sol. These features are lifted Verbatim from Nandan Nilekani’s Blog in TimesofIndia in 2016, where he said, “ Aadhaar provides open Application Programming Interfaces or APIs, which can be integrated easily into any electronic device. These APIs enable online authentication using a fingerprint or iris.” Therefore both statements are right.
S6.Ans. (b)
Sol. Barometer, device used to measure atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
S7.Ans. (a)
Sol. The first steam engine to be applied industrially was the “fire-engine” or “Miner’s Friend”, designed by Thomas Savery in 1698.
S8.Ans. (a)
Sol. The device which is used to measure transpiration in plants is known as Potometer also known as transpirometer. Hygrometer is an instrument used for measuring the moisture content in the atmosphere, Cresco meter or Cresco graph is used to measure the growth in plants, Clinometer is a device which is used to measure the height of tall things that one can’t possibly reach.
S9.Ans. (b)
Sol. Paul Berg (1926), an American biochemist is considered as the father of genetic engineering. He evolved a technique to join DNAs from two different organisms.
S10.Ans. (c)
Sol. Auxanometer is the instrumental apparatus to measure the rate of growth of plants.
