    Pluto has recently been changed from a ______ to a ________, more commonly called dwarf planet.

    • A.

      Planet; star

    • B.

      Planet; asteroid

    • C.

      Planet; trans-neptunian object

    • D.

      Star; planet

    Correct Answer
    C. Planet; trans-neptunian object
    Explanation
    Pluto has recently been changed from a planet to a trans-neptunian object, more commonly called a dwarf planet. This change occurred because the International Astronomical Union redefined the criteria for what qualifies as a planet, and Pluto no longer met those criteria. Instead, it was categorized as a trans-neptunian object, a term that refers to objects that orbit the Sun beyond Neptune's orbit. This reclassification was made to better understand and categorize the various celestial bodies in our solar system.

    Three of what sub-atomic particles make up a proton?

    • A.

      Neutrons

    • B.

      Electrons

    • C.

      Quarks

    • D.

      Atoms

    Correct Answer
    C. Quarks
    Explanation
    Protons are made up of three quarks. Quarks are elementary particles that are considered to be the building blocks of matter. They come in different types, or flavors, such as up, down, charm, strange, top, and bottom. Protons consist of two up quarks and one down quark, which gives them a positive charge. Neutrons, on the other hand, are made up of three quarks as well, but they consist of two down quarks and one up quark, resulting in no charge. Electrons are not sub-atomic particles that make up a proton, but they are negatively charged particles that orbit around the nucleus of an atom. Atoms, on the other hand, are made up of protons, neutrons, and electrons, but they are not sub-atomic particles themselves.

    What is the largest biome on Earth (not counting Ocean)? Hint: It is found south of the tundra.

    • A.

      Taiga

      Desert

    • C.

      Tropical rain forest

    • D.

      Grassland

    Correct Answer
    A. Taiga
    Explanation
    The taiga is the largest biome on Earth, excluding the ocean. It is found south of the tundra and is characterized by its cold climate and extensive forests of coniferous trees. The taiga covers vast areas of North America, Europe, and Asia, making it the largest terrestrial biome. It is home to a diverse range of plant and animal species, including bears, wolves, and moose. The taiga's size and unique ecosystem make it the correct answer to the question.

    Joseph Priestley is the correct answer because he is credited with the discovery of oxygen in 1774. Priestley was an English chemist and theologian who conducted experiments on gases, including the discovery of oxygen gas. His work laid the foundation for the understanding of oxygen's role in combustion and respiration, and he is considered one of the pioneers of modern chemistry.
