    B. organelle
    C. cell
    D. macromolecule

    Answer

    C

    Which of the following sequences represents the hierarchy of biological organization from the most complex to the least complex level?

    A. organelle, tissue, biosphere, ecosystem, population

    D

    Using examples, explain how biology can be studied from a microscopic approach to a global approach.

    Answer

    Researchers can approach biology from the smallest to the largest, and everything in between. For instance, an ecologist may study a population of individuals, the population’s community, the community’s ecosystem, and the ecosystem’s part in the biosphere. When studying an individual organism, a biologist could examine the cell and its organelles, the tissues that the cells make up, the organs and their respective organ systems, and the sum total—the organism itself.

    1.2: The Process of Science

    Multiple Choice

    A suggested and testable explanation for an event is called a ________.

    A. hypothesis
    B. variable
    C. theory
    D. control

    Answer

    A

    The type of logical thinking that uses related observations to arrive at a general conclusion is called ________.

    A. deductive reasoning
    B. the scientific method
    C. hypothesis-based science
    D. inductive reasoning

    Answer

    D

    Give an example of how applied science has had a direct effect on your daily life.

    Answer

    Answers will vary. One example of how applied science has had a direct effect on daily life is the presence of vaccines. Vaccines to prevent diseases such polio, measles, tetanus, and even the influenza affect daily life by contributing to individual and societal health.
