Which of the statements given above is/are correct?
Correct
Answer: b
Explanation:
A breathtaking natural phenomenon recently turned Iran’s Hormuz Island into a global talking point, as its coastlines transformed into a surreal blood-red landscape overnight.

It covers an area of 41.9 sq. km.
It is known for its unique scenery and colorful soil, which has earned it the nickname, “Rainbow Island”.
It is covered by sedimentary rock and volcanic ash.
Because of the lack of precipitation, the soil and water on the island are salty.
The landscape of Hormuz Island is mostly red in color. This is due to a high concentration of iron oxide, especially a mineral called hematite.
Whenever waves from the ocean hit the sands of Hormuz Island, those waves turn pink.
But although the island is well-known for its red landscape, it is also known for various other colors.
Colors to be seen in the island’s sand and soil includered, gold, silver, and white.
It is mostly barren. Hormuz village is the only permanent settlement.
Fishing is the main source of income on the island.
People native to the island belong to an ethnic group known as the Bandari.

Correct
Answer: a
Explanation:
Researchers recently identified three previously unknown species of moths that had remained hidden in the high-altitude landscapes of the Himalayas.

The three species are Gelechia bilobuncusa, Gelechia adi, and Istrianis ladakhensis.
They were discovered in the high-altitude landscapes of the Himalayas.
Gelechia bilobuncusa:
It was found in Himachal Pradesh.
Its name is a scientific nod to the unique bilobed shape of its uncus, a part of the male genitalia.
It is characterised by pale brown wings with irregularly scattered black scales.
Gelechia adi:
It was discovered in the Ramsing area of Arunachal Pradesh.
It is named inhonour of the local Adi tribe inhabiting the Upper Siang district.
It is visually distinct, featuring ivory-white forewings interrupted by a dramatic black streak across the base and triangular spots.
Istrianis ladakhensis:
It is named after its type locality in Ladakh.
This moth is adapted to the high-altitude environment, sporting light brown wings mottled with dark grey, white, and orange scales, distinguishing it from its closest relatives in the genus.

Host range: All decapod crustaceans (order Decapoda), including prawns, lobsters and crabs from marine, brackish or freshwater environments, are considered susceptible to infection.
Symptoms: The affected shrimp exhibit anorexia, lethargy, reddish discoloration and presence of circular white spots on the carapace and other exoskeletal parts.
Transmission: It can be transmitted both horizontally as well as vertically.
Vertical transmission: It occurs from infected brood stock to postlarvae.
Horizontal transmission: It is through carrier animals or through cannibalism of infected organisms.
It has been officially reported from Bangladesh, Burma (Myanmar), Cambodia, China, Hong Kong, India, Indonesia, Iran, Japan, Malaysia, the Philippines, the Republic of Korea, Singapore, Thailand and Vietnam.

With reference to Freshwater Sponge, consider the following:
It is a multicellular eukaryotic species.
It acts as a bio indicator and absorbents of toxic metals.
It is a filter feeder species which grows on sturdy submerged objects in clean streams and lakes.
How many of the above statements are correct?
Correct
Answer: c
Explanation:
Recently, scientists from Bose Institute studied freshwater sponges from the Sundarban delta and identified their potential to act as bio indicators of toxic metal pollution.
Freshwater sponges are the earliest multicellular eukaryotes.
They filter large volumes of water and are vital for ecosystem health.
Habitat: They grow on sturdy submerged objects in clean streams, lakes, and rivers.
Sponges are filter feeders. They obtain food from the flow of water through their bodies and from symbiotic algae.
Appearance: Many freshwater sponges appear green because they contain algae, which live on sponges in a symbiotic relationship.
Reproduction: They can reproduce sexually, or asexually.
When small piece is broken off and grow into new sponges.
The sponge forms gemmules—tiny reproductive spheres that can overwinter and later hatch and form new sponges.
Ecological Role: They act both as bioindicators and absorbents of toxic metals like arsenic, lead, and cadmium and can be a promising solution for bioremediation.
They are effective bio indicators for monitoring water quality and pollution levels in estuarine and freshwater ecosystems.
