Q.2) Consider the following statements with respect to ‘Permafrost’.

1. While permafrost itself is always frozen, the surface layer that covers it need not be frozen.

2. Thawing of permafrost could release greenhouse gases.

Select the correct statements

a) 1 Only

b) 2 Only

c) Both 1 and 2

d) Neither 1 nor 2

Q.2) Solution (c)

Permafrost is ground that remains completely frozen at 0 degrees Celsius or below for at least two years. It is defined solely based on temperature and duration. The permanently frozen ground, consisting of soil, sand, and rock held together by ice, is believed to have formed during glacial periods dating several millennia.

While permafrost itself is always frozen, the surface layer that covers it (called the “active

layer”) need not be. In Canada and Russia, for example, colourful tundra vegetation carpet over

permafrost for thousands of kilometres. Its thickness reduces progressively towards the south,

and is affected by a number of other factors, including the Earth’s interior heat, snow and

vegetation cover, presence of water bodies, and topography.

When permafrost thaws, microbes start decomposing this carbon matter, releasing greenhouse

gases like methane and carbon dioxide. Researchers have estimated that for every 1 degree

Celsius rise in average temperature, permafrost grounds could release greenhouse gases to the

tune of 4-6 years’ of emissions from coal, oil, and natural gas — becoming a major factor of

climate change in themselves.

Along with greenhouse houses, these grounds could also release ancient bacteria and viruses

into the atmosphere as they unfreeze.

Q.3) ‘Serotonin’ is found in

1. Gastrointestinal tract (GI tract)

2. Central nervous system (CNS)

3. Blood platelets

Select the correct code:

a) 1 and 2

b) 2 and 3

c) 1 and 3

Q.3) Solution (d)

It is a monoamine neurotransmitter. It has a popular image as a contributor to feelings of wellbeing and happiness, though its actual biological function is complex and multifaceted,

modulating cognition, reward, learning, memory, and numerous physiological processes such as

vomiting and vasoconstriction.

Serotonin is primarily found in the enteric nervous system located in the gastrointestinal tract

(GI tract). However, it is also produced in the central nervous system (CNS), specifically in the

Raphe nuclei located in the brainstem. Additionally, serotonin is stored in blood platelets and is

released during agitation and vasoconstriction, where it then acts as an agonist to other

platelets.

Q.4) Which of the following statements with respect to ‘Crypto-jacking’.

1. It is the unauthorized use of your computer and devices by cybercriminals in order to

which slows down the system.

Select the correct statements

a) 1 Only

b) 2 Only

c) Both 1 and 2

d) Neither 1 nor 2

Q.4) Solution (c)

Cryptojacking is the malicious use of a person or persons’ computing power to mine

cryptocurrencies without consent.

Unlike most other types of malware, crypto-jacking scripts do not use the victim’s data. But

they drain the CPU’s resources, which slows down the system, increases electricity usage, and

causes irreparable damage to the hardware.

goods, or to do away with import of each and every product in the next five years.

economy.

Q.15) Which of the following are consequences of ‘Ocean deoxygenation’?

1. Decreased biodiversity

2. Shifts in species distributions

3. Reduction in fishery resources

4. Expanding algal blooms

Select the correct code:

a) 1, 2 and 3

b) 2, 3 and 4

c) 1, 3 and 4

d) All of the above

Q.15) Solution (d)

Ocean deoxygenation is one of the most pernicious, yet under-reported side-effects of humaninduced climate change. The primary causes of deoxygenation are eutrophication (increased

nutrient run-off from land and sewage pollution) and nitrogen deposition from the burning of

fossil fuels, coupled with the widespread impacts from ocean warming. Oxygen loss from

warming has alarming consequences for global oceanic oxygen reserves, which have already

been reduced by 2% over a period of just 50-years (from 1960 to 2010).

Consequences of ocean oxygen decline include decreased biodiversity, shifts in species

distributions, displacement or reduction in fishery resources and expanding algal blooms.
