The question asks us to evaluate two statements regarding India's electricity production and uranium enrichment. We need to determine the correctness of each statement individually and then assess if Statement-II provides a correct explanation for Statement-I.
C) Statement-I is correct, but Statement-II is incorrect.
The question asks us to evaluate two statements regarding marsupials and their presence/habitat. We need to determine the correctness of each statement individually and then assess if Statement-II provides a correct explanation for Statement-I.
Marsupials are a group of mammals characterized by giving birth to relatively undeveloped young that typically complete their development in a pouch on the mother's body. The vast majority of marsupials are found in Australia, New Guinea, and the Americas. India is part of Asia, and marsupials are not native to the Indian subcontinent. Therefore, Statement-I is correct.
This statement makes a very restrictive claim about marsupial habitats and predator presence. Marsupials exhibit a wide range of adaptations and inhabit diverse environments, including forests, deserts, and grasslands, not just montane grasslands. Furthermore, marsupials coexist with various predators in their native habitats (e.g., dingoes, birds of prey, snakes in Australia; various carnivores in the Americas). The absence of predators is an unrealistic condition for any thriving wild population. Therefore, Statement-II is incorrect.
Since Statement-II is incorrect, it cannot be a correct explanation for Statement-I.
Correct Option: C) Statement-I is correct, but Statement-II is incorrect
The question asks to identify the parent organization of the 'Invasive Species Specialist Group' (ISSG), which is responsible for developing the Global Invasive Species Database. This requires knowledge of major international environmental organizations and their specific programs or groups.
Therefore, the International Union for Conservation of Nature (IUCN) is the correct parent organization.
A) The International Union for Conservation of Nature (IUCN) — The Invasive Species Specialist Group (ISSG) is part of the Species Survival Commission (SSC) of the IUCN. The ISSG is responsible for developing and maintaining the Global Invasive Species Database (GISD).
The question asks to identify which of the given fauna are generally nocturnal or most active after sunset. We need to analyze the activity patterns of each animal listed.
A) Only one. Based on the analysis, only the Malabar Civet is primarily nocturnal among the given options. The Lion-tailed Macaque is diurnal, and the Sambar Deer is crepuscular.
The question asks to identify the organism that performs a "waggle dance" to communicate the location of food sources to its kin. This is a specific behavior known in the animal kingdom, primarily associated with social insects.
Correct Option: C) Honeybees perform the waggle dance. This intricate dance is a form of symbolic communication where a returning forager bee informs other bees in the hive about the direction and distance to a patch of flowers yielding nectar and pollen, or to a new potential nest site.
The question asks to identify how many of the given statements about mushrooms are correct. We need to evaluate each statement individually based on general scientific knowledge about fungi.
This statement is correct. Many mushrooms are known for their medicinal value and have been used in traditional medicine for centuries. Examples include Reishi (Ganoderma lucidum), Shiitake (Lentinula edodes), and Turkey Tail (Trametes versicolor), which are studied for their immune-boosting, anti-cancer, and anti-inflammatory properties.
This statement is correct. Certain species of mushrooms, often referred to as "magic mushrooms," contain psychoactive compounds like psilocybin and psilocin. These compounds can induce altered states of consciousness, hallucinations, and other psychological effects. A well-known example is Psilocybe cubensis.
This statement is correct. Some fungi, including certain mushrooms, are entomopathogenic, meaning they can infect and kill insects. For instance, species like Cordyceps are known to parasitize insects and are even used in biological pest control. Some mushrooms also produce compounds that are toxic to insects.
This statement is correct. There are several species of mushrooms that exhibit bioluminescence, meaning they can produce and emit light. This phenomenon is often observed in tropical and subtropical regions. Examples include species from the genera Mycena, Panellus, and Omphalotus (e.g., "Jack-o'-lantern mushroom"). The light is produced through a chemical reaction involving a luciferase enzyme.
D) All four statements are correct, as explained above. Each statement describes a known characteristic or property found in at least some species of mushrooms.
The question asks to identify the correct statements regarding Indian squirrels. We need to evaluate each statement based on general biological knowledge about squirrels, specifically Indian squirrels.
B) Only two
Statements 2 and 3 are correct. Indian squirrels store food in the ground and are omnivorous. Statement 1 is incorrect as they primarily build nests in trees, not burrows in the ground.
The question asks us to evaluate the correctness of three statements regarding the growth conditions of microorganisms. We need to determine if microorganisms can survive and thrive in extreme temperatures (above boiling, below freezing) and highly acidic environments.
C) All three statements are correct, as explained above. Microorganisms exhibit remarkable adaptability, allowing them to colonize diverse and extreme environments.
This question tests knowledge about tool use in animals, specifically which animal uses a stick to extract insects from holes. This is a classic example of animal intelligence and problem-solving.
Correct Option: B) Orangutan
The question asks to identify how many of the given applications use hydrofluorocarbons (HFCs). We need to examine each item on the list and determine if HFCs are used in its making or function.
C) Only three
Based on the analysis, HFCs are used in aerosols, foam agents, and fire suppressants (often broadly categorized under fire protection, though 'fire retardants' is a specific term). They are not typically used as lubricants. Therefore, HFCs are used in three of the listed applications (aerosols, foam agents, and fire protection/suppression which might be implied by fire retardants in a broader sense, but strictly speaking, not fire retardants).
