Detailed Solution for Daily Current Affairs MCQ: 30th September 2024 - Question 1


Statement-I correctly highlights how dead coral skeletons obstruct the natural regeneration of coral reefs by providing shelter for macroalgae, impeding herbivory, and intensifying competition with young corals. Statement-II complements this by pointing out that the presence of dead corals disrupts the ecosystem balance, complicating the reef's ability to regenerate organically. Therefore, both statements are correct, and Statement-II logically explains the implications described in Statement-I.

Daily Current Affairs MCQ: 30th September 2024 - Question 2

Consider the following statements:

1. Dead coral skeletons provide a refuge for macroalgae, making it difficult for herbivores to graze on them.

2. Coral reefs can recover more easily after disturbances that leave a flat substrate compared to those that leave dead coral structures intact.

3. Corals typically spawn multiple times a year, which helps them outcompete algae in occupying space on the reef.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ: 30th September 2024 - Question 2

Statement 1: This statement is correct. The complex structure of dead coral skeletons provides shelter for macroalgae (seaweed), making it difficult for herbivores to access and graze on them. This leads to rapid colonization of the reef by seaweed, which outcompetes juvenile corals.

Statement 2: This statement is also correct. Reefs can recover more easily after disturbances such as cyclones that remove coral but leave a flat surface because young corals can settle and grow without substantial competition from macroalgae. A flat substrate provides a more conducive environment for coral regeneration.

Statement 3: This statement is incorrect. Corals typically spawn just once a year, not multiple times. This limited reproductive frequency gives algae, which can reproduce continuously, a competitive edge in occupying space left by dead coral.

Therefore, the correct statements are 1 and 2 only.

Conclusion: The correct answer is Option B: 1 and 2 Only.

Daily Current Affairs MCQ: 30th September 2024 - Question 3

Consider the following statements:

Statement-I:
The dead coral skeletons left behind by coral bleaching events hinder the natural regeneration of coral reefs.

Statement-II:
Dead coral skeletons provide a refuge for macroalgae, making it difficult for herbivores to graze and allowing algae to outcompete juvenile corals.

Statement-III:
The remnants of dead corals alter the ecosystem balance, disrupting the interactions between herbivores, algae, and coral, further impeding coral reef regeneration.

Which one of the following is correct in respect of the statements?

Detailed Solution for Daily Current Affairs MCQ: 30th September 2024 - Question 3

Answer: (a) Both Statement-II and Statement-III are correct, and both of them explain Statement-I.

Explanation:
Statement-I discusses how dead coral skeletons hinder reef regeneration. Both Statement-II and Statement-III correctly describe mechanisms by which dead coral skeletons impede regeneration. Statement-II explains that the skeletons provide shelter for macroalgae, making it difficult for herbivores to graze, allowing algae to dominate, which prevents juvenile corals from establishing. Statement-III further adds that the presence of dead corals disrupts the natural ecosystem balance between herbivores, algae, and coral, complicating the reef’s natural recovery processes. Therefore, both statements are correct and together explain the hindrance to coral reef regeneration.

Daily Current Affairs MCQ: 30th September 2024 - Question 4

Daily Current Affairs MCQ: 30th September 2024 - Question 8

Consider the following statements regarding the LUX-ZEPLIN (LZ) experiment and Neutrino Fog:

1. The LUX-ZEPLIN (LZ) experiment is located at the Sanford Underground Research Facility in South Dakota, USA, and aims to detect dark matter particles.

2. Neutrino Fog refers to the interference caused by cosmic rays in the detection of dark matter particles.

3. The LUX-ZEPLIN (LZ) experiment uses liquid xenon to detect interactions between dark matter particles and xenon atoms.

Detailed Solution for Daily Current Affairs MCQ: 30th September 2024 - Question 8

Statement 1 is correct: The LUX-ZEPLIN (LZ) experiment is indeed located at the Sanford Underground Research Facility in South Dakota, USA, and its primary objective is to detect dark matter particles.

Statement 2 is incorrect: Neutrino Fog does not refer to the interference caused by cosmic rays. Instead, it describes the interference caused by neutrinos in experiments designed to detect dark matter. Neutrinos, not cosmic rays, create a "fog" that can obscure or mimic genuine dark matter interactions.

Statement 3 is correct: The LUX-ZEPLIN (LZ) experiment uses liquid xenon to detect interactions between dark matter particles and xenon atoms. When a dark matter particle interacts with a xenon atom, it generates a minuscule flash of light and liberates electrons, which are then captured by advanced detection equipment.

Thus, the correct answer is Option B: 1 and 3 Only.

Consider the following pairs:

1. Corals: Marine invertebrates composed of genetically identical organisms known as polyps.

2. Zooxanthellae: Microscopic algae that live within coral tissues and perform photosynthesis.

3. Dead Coral Skeletons: Provide a flat substrate that aids in coral regeneration.

4. Coral Reefs: Largest living structures on Earth, playing a vital role in supporting marine biodiversity.

How many pairs given above are correctly matched?

Detailed Solution for Daily Current Affairs MCQ: 30th September 2024 - Question 9

1. Corals: Marine invertebrates composed of genetically identical organisms known as polyps. This is correctly matched. Corals are indeed marine invertebrates made up of polyps.

2. Zooxanthellae: Microscopic algae that live within coral tissues and perform photosynthesis. This is correctly matched. Zooxanthellae are microscopic algae that live inside coral tissues and perform photosynthesis, providing essential nutrients to the corals.

3. Dead Coral Skeletons: Provide a flat substrate that aids in coral regeneration. This is incorrectly matched. Dead coral skeletons hinder reef regeneration by providing shelter for seaweed, which outcompetes juvenile corals. A flat substrate aids in regeneration, but dead coral structures do not typically provide this flat surface.

4. Coral Reefs: Largest living structures on Earth, playing a vital role in supporting marine biodiversity. This is correctly matched. Coral reefs are indeed the largest living structures on Earth and are crucial for supporting a diverse range of marine life.

So, pairs 1, 2, and 4 are correctly matched, while pair 3 is not.

Answer: Option C

Daily Current Affairs MCQ: 30th September 2024 - Question 10

Consider the following statements:

Statement-I:
The LUX-ZEPLIN (LZ) experiment aims to detect dark matter particles using a tank containing liquid xenon.

Statement-II:
Neutrino fog can interfere with the detection of dark matter by mimicking genuine dark matter interactions.

Which one of the following is correct in respect of the above statements?

Detailed Solution for Daily Current Affairs MCQ: 30th September 2024 - Question 10


Statement-I is accurate as the LUX-ZEPLIN (LZ) experiment indeed involves a tank filled with liquid xenon to detect dark matter particles. Statement-II correctly describes neutrino fog and its potential to interfere with dark matter detection by creating signals that can be mistaken for genuine dark matter interactions. However, Statement-II does not directly explain Statement-I; it provides additional context related to interference in dark matter experiments rather than explaining the methodology of the LUX-ZEPLIN (LZ) experiment.
