[Mission 2022] QUIZ – 2022: INSIGHTS STATIC QUIZ, 14 April 2022 – Science & Technology and IR

Solution: c)

The term third generation biofuel refers to biofuel derived from algae. Previously, algae were lumped in with second generation biofuels. However, when it became apparent that algae are capable of much higher yields with lower resource inputs than other feedstock, many suggested that they be moved to their own category.

Solution: a)

Many people think that electrons are consumed in an electric circuit. This is wrong.

We pay the electricity board or electric company to provide energy to move electrons through the electric gadgets like electric bulb, fan and engines, not to consume or destroy electrons.

We pay for the energy that we use, not the number of electrons we consume.

Solution: b)

• Hydrogen is the lightest and first element on the periodic table. Since the weight of hydrogen is less than air, it rises in the atmosphere and is therefore rarely found in its pure form, H2.
• At standard temperature and pressure, hydrogen is a nontoxic, non-metallic, odorless, tasteless, colorless, and highly combustible diatomic gas.
• Hydrogen fuel is a zero-emission fuel burned with oxygen. It can be used in fuel cells or internal combustion engines. It is also used as a fuel for spacecraft propulsion.

Occurrence of Hydrogen:

• It is the most abundant element in the universe. The sun and other stars are composed largely of hydrogen.
• Astronomers estimate that 90% of the atoms in the universe are hydrogen atoms. Hydrogen is a component of more compounds than any other element.
• Water is the most abundant compound of hydrogen found on earth.

Solution: b)

Bangladesh shares land borders with India to the west, north, and east, Myanmar to the southeast, and the Bay of Bengal to the south. It is narrowly separated from Nepal and Bhutan by the Siliguri Corridor, and from China by Sikkim, in the north, respectively.

Solution: b)

ICP will smoothen cross-border movement of cargo trucks by bringing customs and immigration facilities under one roof.

ICP at Nepalgunj is the third ICP on the India-Nepal border and similar facilities at Birgunj and Biratnagar were operationalised in April 2018 and January 2020. India has also built ICPs on the borders with neighbours such as Bangladesh and Pakistan.

A portion on the Indian side is being built at Rupaidiha by Lands Ports Authority of India.
