Solutions

S1.Ans. (d)
Sol. Chickungunia is caused by chickenguniya virus which is an insect borne virus of genus Alphavirus. Symptoms show high fever, maculopapular rash, headache, etc.

S2.Ans. (b)
Sol. Dual Energy X-ray Absorptiometry (DEXA) is used to measure the density or strength of bones.

S3.Ans. (b)
Sol. Karnal bunt is a fungal disease of wheat, durum wheat, and triticale. The causative Organism is Neovossia indica (Tilletia indica).

S4.Ans. (d)
Sol. The local length an nature of lens of a myopic person having a power of 1.25 dioptre will be 80 cm and concave lens.

S5.Ans. (c)
Sol. Oscilloscope is an instrument which allows us to see waves produced by sound. The microphone can then pick up the sound and convert it to an electrical signal which can be displayed on the oscilloscope.

S6.Ans. (a)
Sol. Sphygmomanometer is an instrument to measure the blood pressure. It is made up of an inflatable cuff to restrict the blood flow and a mercury or manometer to measure pressure.

S7.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.

S8.Ans. (b)
Sol. Refrigeration is the process of removing heat from an enclosed space or from any substance for the purpose of lowering the temperature. Refrigeration slows down bacterial action on food so that the food takes a longer time to get spoiled. While, freezing completely stops bacterial action as frozen bacteria are inactive.

S9.Ans. (c)
Sol. Zinc is much more reactive as compared to tin and may react with natural acids and bases in food materials.

S10.Ans. (c)
Sol. When air reaches the dew point at a particular pressure, the water vapour in the air is in equilibrium with liquid water which means that water vapour is condensing at the same rate at which liquid water is evaporating. Below dew point, liquid water will begin to condense.
