1. (c); Intestinal ville (singular villus) are small, finger-like projections that extend into the lumen of the small intestine. Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border.
2. (b); It may seem that current is a vector because it have a magnitude and a direction. But the thing is, a vector always obey the law of addition of vectors. Since current doesn’t obey it and it follows algebraic addition, current is a scalar.
3. (a); The phenomenon of raising outer edge of the curved road above the inner edge is to provide necessary centripetal force to the vehicles to take a safer turn and the curved road is called Banking of Roads.
4. (b); C++ is a general-purpose programming language. It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation.
5. (b); Isobars are atoms (nuclides) of different chemical elements that have the same number of nucleons. In other words, isobars differ in atomic number (or number of protons) but have the same mass number. An example of a series of isobars would be 40S, 40Cl, 40Ar, 40K, and 40Ca.
6. (b); Pitchblende is a radioactive, uranium-rich mineral and ore. It has a chemical composition that is largely UO2, but also contains UO3 and oxides of lead, thorium, and rare earth elements. It is known aspitchblende due to its black color and high density.
7. (b); The Kyoto Protocol was adopted in Kyoto, Japan, on11 December 1997 and entered into force on 16 February 2005. The detailed rules for the implementation of the Protocol were adopted at COP 7 in Marrakesh, Morocco, in 2001, and are referred to as the “Marrakesh Accords.”
8. (c); The 7th pay commission has retained the annual increment of 3%.
9. (b); Charles Louis Alphonse Laveran discovered that malaria was caused by a protozoan parasite in 1880.
10. (d); F1 Australian Grand Prix, 2017 won by Sebastian Vettel; F1 Russian Grand Prix,2017 won by Valtteri Hamilton and F1 Chinese Grand Prix, 2017 won by Lewis Hamilton.
