5. Wasps

Parasitoid species are found in how many of the above kind of organisms?

Option 2 is incorrect: Centipedes : Arthropodes

Option 3 is correct: Flies : Parasitoid

Option 4 is incorrect: Termites: Detritophagous

Option 5 is correct: Wasps: Parasitoid

Parasitoid species: In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation.

Parasitoids are found in a variety of taxa across the insect superorder Endopterygota, whose complete metamorphosis may have pre-adapted them for a split lifestyle, with parasitoid larvae and free-living adults.

There are parasitoids, too, in the Diptera, Coleoptera and other orders of endopterygote insects. Some of these, usually but not only wasps, are used in biological pest control.

3. Statement-I is correct, but Statement-II is incorrect
4. Statement-I is incorrect, but Statement-II is correct

Correct Option: (c)

Explanation:

Subject: Environment

• Statement I is correct: The Indian Flying Fox (Pteropus giganteus) was listed under the vermin category in the Wildlife Protection Act, 1972.
• Statement II is incorrect: The Indian Flying Fox is a frugivore, meaning it primarily feeds on fruits, nectar, and flowers, not on the blood of other animals.

The Indian Flying Fox is one of the largest bat species in the world. It plays a crucial role in the ecosystem by pollinating plants and dispersing seeds. Misconceptions about its diet can lead to unnecessary fear and persecution.

Correct Option: (a)

Explanation:

Subject: Environment

• Statement I is correct: Many chewing gums are considered a source of environmental pollution because they are not biodegradable.
• Statement II is correct: Many chewing gums contain plastic as a gum base, which is non-biodegradable and contributes to pollution.

Chewing gum pollution is a significant environmental issue as it contributes to litter. The synthetic rubber or plastic used in many gums can persist in the environment for a long time, posing challenges for cleanup and waste management.

37.  Which one of the following is the exhaust pipe emission from Fuel Cell Electric Vehicles, powered by hydrogen?

1. Hydrogen peroxide
2. Hydronium
3. Oxygen
4. Water vapour

Correct Option: (d)

Explanation:

Subject: Science and Technology

Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no harmful tailpipe emissions—they only emit water vapor and warm air.

FCEVs use a propulsion system similar to that of electric vehicles, where energy stored as hydrogen is converted to electricity by the fuel cell. Unlike conventional internal combustion engine vehicles, these vehicles produce no harmful tailpipe emissions.

FCEVs are fueled with pure hydrogen gas stored in a tank on the vehicle. Similar to conventional internal combustion engine vehicles, they can fuel in about 5 minutes and have a driving range of more than 300 miles. FCEVs are equipped with other advanced technologies to increase efficiency, such as regenerative braking systems that capture the energy lost during braking and store it in a battery.

38. Recently, the term “pumped-storage hydropower” is actually and appropriately discussed in the context of which one of the following?

1. Irrigation of terraced crop fields
2. Lift irrigation of cereal crop
3. Long duration energy storage
4. Rainwater harvesting system

Correct Option: (c)

Explanation:

Subject: Science and Technology

Pumped storage hydropower is a form of clean energy storage that is ideal for electricity grids reliant on solar and wind power. The technology absorbs surplus energy at times of low demand and releases it when demand is high. Thus, facilitates long duration energy storage.

Supplementary Notes:

There are two main types of pumped hydro:

• Open-loop: with either an upper or lower reservoir that is continuously connected to a naturally flowing water source such as a river.
• Closed-loop: an ‘off-river’ site that produces power from water pumped to an upper reservoir without a significant natural inflow.
