About This Quiz

Science is the broad field that is concerned with phenomena in nature. Additionally, it engages experiments that give rise to useful postulations. These are further tested to make reasonable inferences as numbers or laws. Certain laws namely; Newton's law, Faraday principle among others; were confirmed through scientific methods. How much do you know about science?

    What science is concerned with the composition and decomposition of matter? - ProProfs

    What science is concerned with the composition and decomposition of matter?

    • Chemistry

    • Astronomy

    • Physics

    • Biology

    Correct Answer
    A. Chemistry
    Explanation
    Chemistry is the branch of science that is concerned with the composition and decomposition of matter. It studies the properties, structure, and behavior of substances, as well as the changes they undergo during chemical reactions. Chemistry is specifically focused on understanding the fundamental building blocks of matter, the elements, and how they combine to form compounds. By studying the composition and decomposition of matter, chemistry provides insights into the physical and chemical properties of substances, which has important applications in various fields such as medicine, materials science, and environmental science.

    Who pioneered astronomy? - ProProfs

    Who pioneered astronomy?

    • Charles Lamarck

    • Greg Philips

    • Galileo Galili

    • Albert Einstein

    Correct Answer
    A. Galileo Galili
    Explanation
    Galileo Galili is the correct answer because he is widely recognized as the pioneer of astronomy. He made significant contributions to the field by using telescopes to observe celestial bodies and challenging the prevailing geocentric model of the universe. Galileo's observations and discoveries, such as the moons of Jupiter and the phases of Venus, revolutionized our understanding of the cosmos and laid the foundation for modern astronomy. His work paved the way for future astronomers and greatly advanced our knowledge of the universe.

    Which of these is not a life science? - ProProfs

    Which of these is not a life science?

    • Anatomy

    • Physiology

    • Physics

    • Botany

    Correct Answer
    A. Physics
    Explanation
    Physics is not a life science because it is the study of matter, energy, and the interactions between them, whereas life sciences focus on the study of living organisms and their processes. Anatomy, physiology, and botany are all branches of life sciences that involve the study of the structure and function of living organisms.

    What century saw John Dalton publicize the Atomic Theory? - ProProfs

    What century saw John Dalton publicize the Atomic Theory?

    • 19th century

    • 14th century

    • 17th century

    • 15th century

    Correct Answer
    A. 19th century
    Explanation
    John Dalton publicized the Atomic Theory in the 19th century. This theory proposed that all matter is made up of tiny indivisible particles called atoms. Dalton's work laid the foundation for modern atomic theory and revolutionized our understanding of the composition and behavior of matter. His ideas were groundbreaking and had a significant impact on the development of chemistry and the scientific community as a whole.

    When was the molecular structure of DNA discovered? - ProProfs

    When was the molecular structure of DNA discovered?

    • 1959

    • 1953

    • 1958

    • 1951

    Correct Answer
    A. 1953
    Explanation
    In 1953, the molecular structure of DNA was discovered. This breakthrough discovery was made by James Watson and Francis Crick, along with the help of Rosalind Franklin's X-ray crystallography images. They proposed the double helix structure of DNA, which consists of two strands twisted around each other. This discovery revolutionized the field of genetics and laid the foundation for understanding the mechanisms of heredity and the basis of life itself.

    What year saw the completion of the "Human Genome Project"? - ProProfs

    What year saw the completion of the "Human Genome Project"?

    • 2005

    • 2007

    • 2010

    • 2003

    Correct Answer
    A. 2003
    Explanation
    The completion of the "Human Genome Project" occurred in the year 2003. This project aimed to sequence and map all the genes present in the human genome. It involved an international collaboration of scientists and researchers who worked together to identify and understand the approximately 20,000-25,000 genes that make up human DNA. The successful completion of this project marked a significant milestone in the field of genetics and provided valuable insights into human health and disease.

    Which of these scientists was not involved in Antiquity? - ProProfs

    Which of these scientists was not involved in Antiquity?

    • Erasthosnes

    • Euclid

    • Hipparchus

    • Theophrastus

    Correct Answer
    A. Erasthosnes
    Explanation
    Erasthosnes was not involved in Antiquity. Although he was a prominent Greek mathematician, geographer, and astronomer, he lived during the Hellenistic period, which came after the end of Antiquity. Antiquity refers to the period of ancient history that encompasses the civilizations of Greece and Rome, from around the 8th century BCE to the 6th century CE. Therefore, Erasthosnes cannot be considered a scientist involved in Antiquity.

    Which of these is not a major division of science? - ProProfs

    Which of these is not a major division of science?

    • Formal science

    • Natural science

    • Space science

    • Social science

    Correct Answer
    A. Space science
    Explanation
    Space science is not a major division of science because it is a subfield of natural science. Natural science encompasses the study of the physical world, including physics, chemistry, biology, and earth science. Space science specifically focuses on the study of celestial objects, such as planets, stars, and galaxies, as well as the phenomena that occur in outer space. While space science is an important and specialized field, it is considered a subset of natural science rather than a major division in its own right.
