The word quasar stands for quasi-stellar radio source. Quasars got that name because they looked starlike when astronomers first began to notice them in the late 1950s and early 60s. But quasars aren’t stars. They’re now known as young galaxies, located at vast distances from us, with their numbers increasing towards the edge of the visible universe. How can they be so far away and yet still visible? The answer is that quasars are extremely bright, up to 1,000 times brighter than our Milky Way galaxy. We know, therefore, that they’re highly active, emitting staggering amounts of radiation across the entire electromagnetic spectrum.

Solution: d)

Tagging of Olive Ridley sea turtles at Rushikulya rookery along Odisha coast, would help scientists identify the migration path and places visited by the marine reptiles after congregation and nesting.

We are studying the path taken by turtles in the sea, if they keep coming to one nesting site for laying eggs, and the number of sites they visit over the years. Besides, the growth of turtles could be measured during the  study.

The study would also reveal the inter-rookery movement of turtles in Odisha. The migration pattern to other countries would be recorded in detail.

Solution: b)

Bio-CNG is a purified form of biogas with over 95% pure methane gas. It is similar to natural gas in its composition (97% methane) and energy potential. While natural gas is a fossil fuel, Bio-CNG is a renewable form of energy produced from agricultural and food-waste. Bio-CNG is being looked at as an environment-friendly alternative to diesel.

This Bio-CNG can be used to power automobiles with the same efficiency as fossil fuel CNG.

Bio-CNG has a high calorific value and can be used in blast furnaces; also it can be converted into electricity.

Various sources of biomass are as follows:

Solution: b)

During the framing of the Indian Constitution, it was proposed that any petition alleging a breach of fundamental rights by the state ought to be judicially decided within one month. While the proposal did not, ultimately, find its way into the text of the Constitution.

The responsibility for constituting benches and scheduling cases especially cases that are due to be heard by larger Benches rests solely with the Chief Justice of India (CJI).
