    Basically, cells are the basic units of life and living organisms are made up of one or more cells
  2. Some prokaryotic cells are "anaerobic" referring to their:
    They don't need oxygen to live
  3. Small cells tend to have:
    Increased membrane surface area
  4. The process of making proteins is:
    transcription & translation -- engineer & factory -- copy plans & send them off to be assemble

    Vacuoles
  6. The endoplasmic reticulum is:
    the “cell highway” that performs transportation duties within a cell
  7. Every cell has the following three components:
    Cell Membrane, cytoplasm, genetic material
  8. One of the functions of a vacuole in a plant cell is to:
    store, support, and regulate water

    ATP
  10. Moving hydrogen ions from one side of a membrane to the other:
    Proton pump
  11. The lifespan of a lipid bilayer in the membranes is generally:
    measured in hours
  12. The “Endosymbiosis Hypothesis” proposes that:
    Mutualistic relationship between different organisms and capable of independent reproduction
  13. The overall function of mitochondria is to:
    “Cell power plant” Used to generate most of the cells store of ATP -- also Break down fats and sugar to ATP.
  14. Which of the following are examples of kinetic energy?:
    Wind, flowing stream, electricity, heat
  15. The First Law of Thermodynamics tells us that:
    whatever energy you put into a system is energy you will get out
  16. As “energy organelles” plant cells have:
    chloroplasts
  17. The first orgasms on Earth occurred about:
    3.8 billion years ago
  18. Autotrophic organisms get their energy from:
    Photosynthesis
  19. The early atmosphere of the Earth had:
    Hydrogen, ammonia, methane, water vapors, but NO oxygen
  20. “Family” is a level in the Linnaean classification hierarchy between:
    Order and Genus
  21. When tectonic plates tipped, they influenced evolution by:
    Changing the environment with the movement of continents, coastlines varied, sea levels changed
  22. The multicellular kingdoms differ in their:
    cells (prokaryotic/eukaryotic) - how they eat - plants: photosynthesis, fungi: absorbtion, animals: ingestion Modes of Nutrition
  23. Scientific names are used instead of common names because:
    Universal and more efficient
  24. Linnaeus named a plant “Siegesbeckia” in order to:
    Spite the guy that the plant is named after
  25. In which Kingdom do we classify viruses?
    None
  26. Viruses are composed of:
    capsid & genetic material.
  27. are viruses that attack bacteria.
    Bacteriophage
  28. HIV infection attacks the:
    T4 lymphocytes (immune system cells); basically attacks the whole immune system
  29. Which of the following is true of viruses outside the host cell?
    viruses exist as a protein coat or capsid, sometimes enclosed within a membrane. The capsid encloses either DNA or RNA which codes for the virus elements. While in this form outside the cell, the virus is metabollically inert --- someone double check this!
  30. Which of the following human diseases is not caused by viruses?
    flu
  31. HIV stands for:
    Human Immunodeficiency Virus
  32. The Spanish Flu:
    influenza pandemic that spread widely across the world.-- also known as H1N1. 20-50 million deaths worldwide.
  33. A problem associated with the development of a vaccine against the Bird Flu virus:

    ???
  41. The two kingdoms that are most different are:
    Monera vs. Protista
  42. Azolla and its associated cyanobacterium are:
    Symbiotic and helpful to the growth of other plants
  43. An example of why the two kingdom system of classification was not workable is:
