  1. Why study Biology
    Biology tells how systems and organisms function, and how we live, develop, modify and refine ideas about life.
  2. What are the molecules of life?
    • Nucleic acids
    • Proteins
    • Lipids
    • Carbohydrates
  3. What are nucleic acids?
    • DNA
    • RNA
  4. What are the most common elements in life?
    • C Carbon
    • H Hydrogen
    • O Oxygen
    • P Phosphorous
    • S Sulfur
    • N Nitrogen
  5. Life’s levels of organization are:
    • Atom
    • Molecule
    • Biomolecule
    • Organelle
    • Cells
    • Tissue
    • Organ
    • Organ systems
    • Organism
    • Population
    • Community
    • Ecosystem
    • Biosphere
  6. Metabolism
    Reaction by which cells acquire and use energy to grow, survive and reproduce.
  7. Energy
    Capacity to do work
  8. Nutrient
    Type of atom or molecule that has essential role in growth and survival and that an organism cannot make for itself.
  9. Producers
    • Autotroph
    • Heterotroph
    • Break down remains / waste.
  10. Life's Domains
    • Bacteria
    • Archaea
    • Eukarya
  11. Six Kingdoms
    • Archaebacteria
    • Eubacteria
    • Protists
    • Fungi
    • Plants
    • Animals
  12. Nature
    Everything that is not artificial
  13. Atoms
    Fundamental building blocks of all substances
  14. Molecules
    forms when two or more atoms of the same or different elements join in chemical bonds
  15. Population
    Group of individuals fo the same kind of organism in a specified area.
  16. Community
    All populations of all species in a specified area
  17. Ecosystem
    A community interacting with its physical and chemical environment.
  18. Bioshpere
  19. Homeostasis
    Sensing and adjusting conditions of internal environment to maintain favorable conditions.
  20. Shell model
    Helps us check an atom for vacancies
  21. Atoms are chemically inactive if...
    It has no vacancies in its outermost shell
  22. Electronegativity
    A measure of an atom’s ability to pull electrons from other atoms
  23. Chemical bond
    An attractive force that arises between tow atoms when their electrons interact
  24. Compounds
    Molecules that consist of two or more different elements in proportions that do not vary
  25. Ion
    An atom with different numbers of electrons and protons
