    Quantum entanglement is a phenomenon in quantum mechanics where two or more particles become interconnected in such a way that the state of one particle instantly affects the state of the other, no matter how far apart they are. This “spooky action at a distance,” as Einstein famously called it, means that the properties of entangled particles are correlated, and changes to one will immediately reflect in the other, even across vast distances.

    Key Features of Quantum Entanglement:

    1. Non-locality: The effect of one particle on another happens instantaneously, seemingly defying the classical idea that no information can travel faster than the speed of light.
    2. Superposition: Each particle in an entangled pair exists in a state of superposition, meaning that its properties (like spin or polarization) are not definite until measured. Once measured, both particles’ states become definite and correlated.
    3. Bell’s Theorem: This theory, confirmed by experiments, shows that no local hidden variables can explain the correlations between entangled particles, which means classical physics cannot fully account for this behavior.

    Applications:

    Quantum entanglement has real-world applications, including:

    • Quantum Computing: Entanglement is a key feature in quantum bits (qubits), enabling quantum computers to perform complex calculations more efficiently than classical computers.
    • Quantum Cryptography: Entanglement is used in secure communication protocols like quantum key distribution (QKD), which ensures that any attempt to intercept the communication can be detected.
    • Teleportation: Quantum entanglement forms the basis of quantum teleportation, where the state of a particle can be transferred to another particle over long distances.

    In essence, quantum entanglement defies classical intuition, pointing to the interconnected nature of quantum systems.

    Hydrofluorocarbons (HFCs) are synthetic chemicals widely employed in industries, mainly for refrigeration and cooling purposes. These man-made compounds were introduced as alternatives to ozone-depleting substances that are being phased out under the Montreal Protocol. HFCs are specifically designed for applications in refrigeration, air-conditioning, aerosol propellants, and insulating foams, with additional, smaller roles in fire protection and as solvents. Unlike some other compounds, HFCs lack lubricating properties. Therefore, the correct option is Only three.

    Here’s an explanation for each statement:

    1. Some microorganisms can grow in environments with temperatures above the boiling point of water: This is correct. Certain microorganisms, known as thermophiles or hyperthermophiles, can thrive in extremely hot environments, such as hydrothermal vents, where temperatures exceed 100°C (the boiling point of water at sea level).
    2. Some microorganisms can grow in environments with temperatures below the freezing point of water: This is correct. Psychrophiles are microorganisms that can grow in extremely cold environments, including those with temperatures below 0°C, such as in polar regions or glaciers.
    3. Some microorganisms can grow in a highly acidic environment with a pH below 3: This is correct. Acidophiles are microorganisms that can thrive in highly acidic conditions, including environments with pH levels as low as 1, such as in acid mine drainage or acidic hot springs.

    Thus, all three statements are correct. The correct answer is All three.

    It looks like the text is explaining the habits and habitats of Indian squirrels and verifying the correctness of certain statements about them. Here’s a brief summary:

    1. Habitat: Indian squirrels are found in India (south of the Vindhyas) and Sri Lanka, living in various environments like forests, grasslands, and urban areas.
    2. Behavior: They are solitary, active during the day, and build nests in treetops.
    3. Food Storage: They store nuts and seeds in the ground for times when food is scarce.
    4. Diet: They are omnivores, eating nuts, fruits, seeds, insects, small mammals, reptiles, eggs, and sometimes bird chicks.

    Based on this information, the correct answer to the question seems to be option only two.

    The correct answer is: Honey Bees. Honey bees perform the “waggle dance” to communicate the direction and distance of a food source to other members of their hive. The dance involves a series of movements, including waggling their bodies and making figure-eight patterns, to convey information about the location of nectar, pollen, or water. This sophisticated form of communication is crucial for the foraging efficiency and survival of the colony. Neither butterflies, dragonflies, nor wasps use this method of communication.

    2. Malabar Civet: The Malabar Civet is generally nocturnal. It is most active during the night and is rarely seen during the day. It is a critically endangered species native to the Western Ghats and nearby regions.
    3. Sambar Deer: The Sambar Deer is largely nocturnal or crepuscular (active during twilight). It tends to be most active during the early morning and late evening but can also be seen foraging at night.

    Given this information, two of the listed fauna (Malabar Civet and Sambar Deer) are generally nocturnal or most active after sunset. Therefore, the correct answer is: Only two.

    Let’s analyze each statement:

    Statement-I: India, despite having uranium deposits, depends on coal for most of its electricity production. This statement is correct. Although India has some uranium deposits, they are not sufficient to meet the country’s nuclear energy needs. As a result, India imports uranium and heavily relies on coal, which is abundant and cheaper, for most of its electricity production.

    Statement-II: Uranium, enriched to the extent of at least 60%, is required for the production of electricity. This statement is incorrect. For nuclear reactors used in electricity production, uranium is typically enriched to about 3-5% U-235. Enrichment levels of 60% and above are considered high and are used for research reactors or weapons-grade material, not for commercial electricity generation.

    Therefore, the correct answer is: Statement-I is correct but Statement-II is incorrect.
