    Rate this question:

  • 5. 

    Large regions that have about the same temperature and amount of rain or snow are known as

    • A.

      Ecosystems

    • B.

      Biomes

    • C.

      Abiotic areas

    • D.

      Ecological reserves

    Correct Answer
    B. Biomes
    Explanation
    Biomes are large regions characterized by similar temperature and precipitation patterns. They are defined by the dominant plant and animal species that inhabit them. Biomes can include various ecosystems within them, but they are distinguished by their overall climate and vegetation. The term "abiotic areas" does not accurately describe regions with similar temperature and precipitation, and "ecosystems" and "ecological reserves" are more specific terms that refer to smaller-scale areas within biomes. Therefore, the correct answer is biomes.

    Which statement correctly describes the electrons in a water molecule?

    • A.

      Electrons are pulled closer to the hydrogen atoms.

    • B.

      Electrons are pulled closer to the oxygen atom.

    • C.

      Electrons are located inside the nucleus of the hydrogen atoms.

    • D.

      Electrons are an equal distance between hydrogen and oxygen.

    Correct Answer
    B. Electrons are pulled closer to the oxygen atom.
    Explanation
    In a water molecule, the oxygen atom has a higher electronegativity than the hydrogen atoms. This means that the oxygen atom has a greater ability to attract electrons towards itself. As a result, the electrons in a water molecule are pulled closer to the oxygen atom, creating a partial negative charge around the oxygen and partial positive charges around the hydrogen atoms. This distribution of electrons is responsible for the polar nature of water.

    • A.

      Density dependent

    • B.

      Density independent

    • C.

      Population dependent

    • D.

      Population independent

    Correct Answer
    A. Density dependent
    Explanation
    Density dependent limiting factors are those that become more significant as the population size increases. These factors include competition for resources, predation, disease, and parasitism. In a large population, the competition for resources and the spread of diseases or parasites are more intense, leading to a greater impact on the population. In contrast, density independent limiting factors, such as natural disasters or climate events, affect populations regardless of their size. Therefore, density dependent limiting factors affect a large population more than a small population.

    By which process does water vapor become a cloud?

    • A.

      Evaporation

    • B.

      Transpiration

    • C.

      Condensation

    • D.

      Precipitation

    Correct Answer
    C. Condensation
    Explanation
    Water vapor becomes a cloud through the process of condensation. Condensation occurs when water vapor in the air cools down and changes into liquid water droplets. This happens when warm, moist air rises and encounters cooler temperatures higher in the atmosphere. As the air cools, it can no longer hold as much water vapor, causing the excess moisture to condense into tiny water droplets or ice crystals. These droplets or crystals then come together to form clouds.
