    Let's evaluate the pairs one by one: Cepheids: These are stars that brighten and dim periodically due to changes in their size and temperature.

    Let’s evaluate the pairs one by one:

    1. Cepheids: These are stars that brighten and dim periodically due to changes in their size and temperature. The description in the pair refers to stars and not to giant clouds of dust and gas. Hence, this pair is incorrect.
    2. Nebulae: Nebulae are giant clouds of dust and gas in space, not stars that brighten and dim periodically. The description in the pair is incorrect. Hence, this pair is incorrect.
    3. Pulsars: Pulsars are indeed neutron stars that emit beams of radiation, and they are formed when massive stars run out of fuel and collapse. The description in the pair is accurate. Hence, this pair is correct.

    Therefore, only one of the pairs is correctly matched.

    The answer is: Only one.

    Biofilters play a crucial role in Recirculating Aquaculture Systems by eliminating nitrogenous waste produced by aquatic organisms. They utilize nitrifying bacteria to transform toxic ammonia into nitrites, which are also harmful. Subsequently, other bacteria further convert these nitrites into harmless nitrates, ensuring water quality. Importantly, biofilters are engineered to remove pollutants rather than introduce nutrients into the system, making statement 3 inaccurate.

    The correct answer is All three.

    Here’s how an accelerometer is involved in each action:

    1. Detection of Car Crash/Collision

    • An accelerometer detects rapid deceleration or impact forces, which triggers the deployment of airbags almost instantaneously.
    • Function of accelerometer: Required.

    2. Detection of Free Fall of a Laptop

    • Accelerometers sense sudden free-fall motion (near-zero acceleration in free fall) and can signal the hard drive to turn off immediately to prevent damage.
    • Function of accelerometer: Required.

    3. Detection of Tilt of a Smartphone

    • Accelerometers measure the tilt or orientation of the device relative to gravity, allowing the display to rotate between portrait and landscape modes.
    • Function of accelerometer: Required.

    An accelerometer is required in all three actions, as it plays a crucial role in detecting motion, orientation, or force changes in each scenario. Thus, the correct answer is All three.

    The evolution of humans (Evolution) is a long and complex process that traces back millions of years. It explains how modern humans (Homo sapiens) evolved from ancient ancestors. The primary stages of human evolution, based on scientific findings, are as follows:

     

    Evolution of Life on Earth:

    • The origin of life began about 3.8 billion years ago with simple single-celled organisms.
    • Over time, more complex multicellular organisms developed, leading to the evolution of various species, including primates, the group to which humans belong.

    Key Stages of Human Evolution:

    1. Australopithecus (4 to 2 million years ago):

    • Early ancestors of humans.
    • Walked upright on two legs but had a small brain.
    • Example: Australopithecus afarensis (e.g., “Lucy”).

    2. Homo habilis (2.4 to 1.4 million years ago):

    • Known as the “handy man” for using stone tools.
    • Larger brain compared to Australopithecus.

    3. Homo erectus (1.9 million to 110,000 years ago):

    • First human ancestor to use fire and migrate out of Africa.
    • Lived in groups and developed more advanced tools.

    4. Neanderthals (Homo neanderthalensis) (400,000 to 40,000 years ago):

    • Lived in Europe and parts of Asia.
    • Stocky build with a large brain.
    • Created tools, used fire, and may have had rituals.

    5. Homo sapiens (Modern Humans) (200,000 years ago to present):

    • Developed sophisticated tools, language, and culture.
    • Migrated globally and adapted to various environments.
    • Domesticated animals and developed agriculture, leading to civilization.

    Main Features of Human Evolution:

    • Bipedalism: Walking on two legs.
    • Larger Brain Size: Leading to better problem-solving and communication.
    • Use of Tools: From simple stones to complex machines.
    • Development of Language: Allowed for communication and cultural transmission.
    • Social Structures: Formation of families, tribes, and societies.

    Human evolution is a gradual process driven by natural selection, adaptation, and environmental changes. It highlights the remarkable journey of humans from primitive ancestors to the dominant species shaping the world today.

    The existence of ghosts is a widely debated topic, with opinions varying based on cultural beliefs, personal experiences, and scientific perspectives. From a scientific standpoint, there is no concrete evidence to prove the existence of ghosts. Many alleged ghost sightings can be explained by psychological factors, illusions, or environmental causes. For instance, fear, stress, or phenomena like sleep paralysis can make people believe they have encountered supernatural entities. Unexplained noises, shadows, or movements are often attributed to natural causes such as wind, old structures, or electromagnetic fields.

    On the other hand, many cultures and religions around the world hold a strong belief in spirits or supernatural entities, often tied to the idea of life after death or the notion of spirits interacting with the living to fulfill unfinished business or provide guidance. Personal experiences also play a significant role in shaping beliefs, as many individuals claim to have encountered or felt the presence of ghosts. Paranormal investigations and ghost-hunting groups attempt to provide evidence, but findings are often inconclusive.

    Psychological and social factors also contribute to belief in ghosts. The placebo effect can lead people to interpret normal events as supernatural, while cultural influences such as stories, movies, and traditions shape perceptions of the paranormal. While there is no scientific proof of their existence, belief in ghosts persists due to cultural traditions, personal experiences, and psychological interpretations. Whether ghosts are real or not remains a mystery, captivating and intriguing people across the world.
