  1. Organ
    a group of similar cells performing a similar job
  2. What is the smallest level of organization? (smallest living unit)
    Cell
  3. What are the building blocks of protein?
    Amino acids
  4. What are the monomers for carbohydrates?
    monosaccharides
  5. What are the monomers for RNA and DNA?
    Nucleotides
  6. Which type of cell has nucleic acid that is not membrane bound? (prokaryote or eukaryote?)
    Prokaryote
  7. Which type of cell is older, prokaryote or eukaryote?
    Prokaryote
  8. Which is larger, prokaryote or eukaryote?
    Eukaryotes
  9. Which cell type are bacteria, prokaryote or eukaryotes?
    Prokaryote
  10. Which cell type are plants, prokaryote or eukaryote?
    Eukaryotes
  11. What was attempted in the Miller-Urey experiment?
    The creation of amino acids
  12. What is the endosymbiotic thoery?
    Ancient anerobic prokaryotes were brought into aerobic bacteria, which were then brought into primitive aerobic eukaryotes, resulting in photosynthetic eukaryotes.
  13. What is the function of protein channels?
    To allow certain substances to pass the cell membrane.
  14. In which part of the membrane does osmosis take place?
    (semi permeable membrane)
  15. What will happen to a potato slice put into salt water and why?
    It will dry out; the salt water has a lower percentage of water in it, and the water from the potato will therefore be pulled out.
  16. What will happen to a potato slice put into distilled water?
    It will gain water, because it has more solutes in it.
  17. If an egg is placed in water with less solutes than is in the egg, what will happen?
    It will gain water.
  18. What is osmosis?
    Diffusion across a semi-permeable membrane
  19. Which organelle of a cell controls all the energy?
    Nucleus
  20. What is the formula for photosynthesis?
    CO2 + H2O => O2 + C6H12O6 + H2O
  21. What is the formula for respiration?
    C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy
  22. What enzyme does the liver contain?
    Catalase
  23. Which type of respiration produces more ATP?
    Aerobic
  24. How many ATP are produced in aerobic respiration? Anaerobic?
    • 36 in aerobic
    • 4 in anaerobic
  25. What were Watson and Crick best known for?
    Discovering the double helix (even though they stole work form a woman..)
  26. What was Mendel best known for?
    Studying heredity
  27. Does RNA or DNA have a base noted as U?
    RNA
  28. Which molecule copies the single DNA strand?
  29. Which molecule carries the amino acid to the mRNA strand?
  30. At which molecule does translation take place?
  31. Where does transcription take place?
  32. How are mutations inherited?
    When the mutations are found in the gametes
  33. How are mutations not inherited?
    When changes are in somatic, or body, cells
  34. What are two environmental causes of gene mutations?
    Chemicals, viruses
  35. Cancer could be a result of what type of mutation?
  36. What is a codon?
    Three sets of base pairs
  37. What biological compound regulates all cell processes?
  38. How many daughter cells result from mitosis?
    2
  39. Are the cells produced my mitosis asexual or sexual?
    Asexual
  40. Does mitosis produce cells with the same, less, or more chormosomes as the parent cell?
    Same
  41. How many daughter cells result from meiosis and are they sexual or asexual?
    4, sexual
  42. How many chromosomes will a human gamete cell have?
    23
  43. What's a dihybrid cross?
    A corss between true breeding parents which differ in two, unlinked traits.
  44. Autosomal dominant pedigree
  45. Sex-linked recessive pedigree
  46. Match DNA
  47. What are the conditions for the Hardy-Weinberg equillibrium?
    • No mutation
    • large population
    • random mating
    • no immigration/emigration
    • No natural selection
  48. If in Hardy-Weinbery Equilibrium, is there a greater chance of allele frequency change?
    No, there's is a smaller chance.
  49. What's gene flow?
    Immigration/emigration of alleles
  50. What's genetic drift?
    An allele can become common in a small population
  51. What's natural selection?
    Survival of the fittest
