  1. Explain the
    properties an object must have to be considered alive?
    Complex order

    Regulation of internal environment

    Growth and development

    • Energy is actively taken in from the
    • environment

    Response to the environment

    • Reproduction-ability to faithfully replicate
    • new generations

    • Evolution-ability of populations to
    • change generations
  2. What are the
    hierarchical levels that biologist study and how do they relate to each other?
    Atoms

    Molecular-cluster of atoms

    • Cell-smallest unit of living matter
    • separated by membrane

    • Tissue-group of similar cells with
    • specialized function

    • Organ-group of different tissues that
    • have a specific function

    • Organ System-group of organs with a
    • specific function

    Organism-an individual living thing

    • Population-a group of interacting individuals
    • of the same species

    • Community-the populations of species
    • in an area which interact in some way

    • Ecosystem-community of living
    • organisms and the physical components of the environment for a given are

    • Biosphere-all environments that
    • support life on earth
  3. What is an
    emergent property?
    • It's the property where living things become more and
    • more complex as it goes from cellular level (exp humans are made of cells) to
    • organ system (exp humans are made of organ system composed of millions of
    • cells).
  4. How are living
    things classified into domains, and is domain a more inclusive or less
    inclusive grouping than a kingdom?
    Eukarya, Archaea, and Bacteria

    • Domains are more inclusive because it
    • contains plants and tress as well.
  5. Which domain
    contains prokaryotes, which contain eurkaryotes?
    • Domains Bacteria and Archae contain
    • prokaryotes

    • Domain Eukarya contain eukaryotes,
    • plantae, animalia, fungae, and protista
  6. What is the
    difference between discovery science and hypothesis-driven science?
    • Discovery science is a specific
    • observation that produces a general conclusion or idea

    • Hypothesis-driven science begins with
    • a question or a problem that can be tested
  7. How does the
    Scientific Method work?
    Observation>Question>Hypothesis>Prediction>Test

    • IF TEST SUPPORTS HYPOTHESIS: make
    • additional predictions and test them

    • IF TEST DOES NOT SUPPORT HYPOTHESIS:
    • revise hypothesis or pose a new one
  8. How does theory
    differ from hypothesis?
    • Theory have been tested, where hypothesis can be
    • tested
  9. What is a
    testable hypothesis & and falsifiable hypothesis?
    • Testable hypothesis is a hypothesis
    • that can be tested

    • Falsifiable hypothesis is a hypothesis
    • that can be disproven by experimentation
  10. Essay Question:  List three ways in which an advanced robot
    might have the properties of a living organism, and briefly support your
    answer.
