ANSWER..............

01Answer: B [Christian Gottfried Ehrenberg]
Notes:
Christian Gottfried Ehrenberg was a was one of the most famous and productive scientists of his time. He was a German naturalist, zoologist, comparative anatomist, geologist, and microscopist. He coined the term Bacterium.

02 Answer: C [It’s a new technology related to synthesis of artificial blood]
Notes:
PRINT (Particle Replication in Non-wetting Templates) Technology is a new technology related to synthesis of artificial blood. PRINT method has been widely applied onto material sciences, drug delivery, electronic devices, optics, etc.

03 Answer: A [Potato and Brinjal]
Notes:
Potato and Brinjal have several common features and are thus included in the same genus Solanum. The scientific name of Potato is Solanum tuberosum and Brinjal is Solanum melongena.

04 Answer: D [√2 times]
Notes:
It means that if the speed of a satellite orbiting close to the earth is made √2 times (or increased by 41%) then it will escape from the gravitational field.

05 Answer: B [poiseiulle]
Notes:
The SI unit of viscosity is poiseiulle (Pl). Its other units are N s m^-2 or Pa s.

06 Answer: A [twice the distance between two consecutive nodes or antinodes]
Notes:
Wavelength (λ) of a progressive wave is the distance between two consecutive points of the same phase at a given time. In a stationary wave, it is twice the distance between two consecutive nodes or antinodes.

07Answer: A [Aluminium]
Notes:
The speed of sound decreases when we go from solid to gaseous state.

08 Answer: C [Both 1 & 2]
Notes:
The metallic oxides react with acids to give salts and water. It is similar to the reaction of a base with an acid, Therefore metallic oxides are normally basic oxides.

09 Answer: B [Ethene]
Notes:
Ethene is used in the polymerisation process to produce polythene. The process of formation of polymers from respective monomers is called polymerisation.

10 Answer: D [Nylon 6,6]
Notes:
Nylon 6,6 is a synthetic polymer which can be formed due to the reaction of hexamethylene diamine and adipic acid.
