    Astrobiology investigates the possibility of life on other

    • Stones

    • Planets

    • Animals

    • Humans

    Correct Answer
    A. Planets
    Explanation
    Astrobiology is a field of study that explores the potential existence of life on other planets. It involves the study of various factors such as the presence of water, suitable atmospheric conditions, and the potential for organic molecules to form. By focusing on planets, astrobiologists aim to understand whether conditions necessary for life, as we know it, could exist beyond Earth. This answer is correct because it aligns with the main focus and objective of astrobiology.

    Organisms that are able to survive in extreme environments are - ProProfs

    Organisms that are able to survive in extreme environments are

    • Extremist

    • Extremophiles

    • Animals

    • Plants

    Correct Answer
    A. Extremophiles
    Explanation
    Extremophiles are organisms that can survive in extreme environments. These environments can include extreme temperatures, high pressures, acidic or alkaline conditions, and high levels of radiation. Extremophiles have adapted to these harsh conditions through various mechanisms, such as producing special enzymes or protective proteins. They can be found in diverse habitats like deep-sea hydrothermal vents, hot springs, polar regions, and even within rocks deep underground. Extremophiles play a crucial role in scientific research, as their unique adaptations can provide insights into the limits of life on Earth and the potential for life in other extreme environments, such as on other planets.

    The Big Bang was how many billion years ago? - ProProfs

    The Big Bang was how many billion years ago?

    • 11

    • 13.8

    • 12

    • 9

    Correct Answer
    A. 13.8
    Explanation
    The correct answer is 13.8. This is the estimated age of the universe based on scientific evidence, such as the observation of cosmic microwave background radiation and the rate of expansion of the universe. These measurements suggest that the Big Bang occurred approximately 13.8 billion years ago, marking the beginning of our universe.

    Methane consists of carbon and - ProProfs

    Methane consists of carbon and

    • Silicon

    • Neon

    • Hydrogen

    • Water

    Correct Answer
    A. Hydrogen
    Explanation
    Methane consists of carbon and hydrogen. This is because methane, which is the simplest hydrocarbon, is composed of one carbon atom bonded to four hydrogen atoms. Therefore, the correct answer is hydrogen.

    Which of these carry biological information? - ProProfs

    Which of these carry biological information?

    • Carbon

    • Helium

    • Titanium

    • Neon

    Correct Answer
    A. Carbon
    Explanation
    Carbon carries biological information because it is a fundamental element found in all living organisms. It is a key component of organic molecules such as proteins, carbohydrates, lipids, and nucleic acids, which are essential for life processes. Carbon atoms can form stable covalent bonds with other elements, allowing for the creation of complex molecular structures and the transfer of genetic information. Therefore, carbon is crucial for the formation and functioning of biological systems.

    What do you study in Astrobiology

    • Process

    • Extraterrestial life

    • Life

    • Biology

    Correct Answer
    A. Extraterrestial life
    Explanation
    Astrobiology is the study of life in the universe, including the possibility of extraterrestrial life. It explores the origins, evolution, and distribution of life on Earth and other celestial bodies. By studying the conditions necessary for life to exist, astrobiologists aim to understand if life exists beyond Earth and how it might have originated. This field combines knowledge from various scientific disciplines such as biology, chemistry, physics, and astronomy to investigate the potential for life in the universe.

    The origin of life is known as - ProProfs

    The origin of life is known as

    • Genesis

    • Abiogenesis

    • Evolitiom

    • Birth

    Correct Answer
    A. Abiogenesis
    Explanation
    Abiogenesis refers to the scientific theory that suggests life on Earth originated from inanimate matter, without the involvement of any preexisting living organisms. It proposes that under the right conditions, such as the presence of certain chemicals and energy sources, simple organic molecules could have formed and eventually led to the development of more complex organisms. This theory is supported by various experiments and observations, including the Miller-Urey experiment that demonstrated the formation of organic compounds in a simulated early Earth environment. Therefore, abiogenesis is the correct answer as it accurately describes the concept of the origin of life.

    Which is an organic compound of life? - ProProfs

    Which is an organic compound of life?

    • Uracil

    • Vitamin

    • Water

    • Colour

    Correct Answer
    A. Uracil
    Explanation
    Uracil is an organic compound of life because it is one of the four nucleobases that make up the genetic code in RNA. It is involved in the synthesis of RNA molecules, which are essential for protein synthesis and gene expression. Uracil is not found in DNA, but it plays a crucial role in the transfer of genetic information from DNA to proteins. Therefore, uracil is an important organic compound that is directly involved in the fundamental processes of life.
