Cards in this deck (36)

  1. 1What are six characteristics of living things?Grows/develops
    Genetic code
    Reproduces
    Responds to stimulus
    Exchanges materials with environment
    Evolves
    Made up of cells
    Homeostasis
  2. 2Provide an example of growth and developmentincreasing in size or change, metamorphosis
  3. 3Provide an example of genetic codeDNA
  4. 4Provide an example of reproductionoffspring, passing on DNA
  5. 5Provide an example of response to stimulusmovement of plants toward light
  6. 6Provide an example of exchange of materials with the environmentplants and photosynthesis, humans eat plants for energy and excrete waste
  7. 7Provide an example of evolutionpopultions change genetically over time
  8. 8Provide an example of cellsingle celled organisms, multi-cellular organisms (plants and animals)
  9. 9Provide an example of homeostasisThermoregulation
  10. 10Define TaxonomyThe discipline of identifying and grouping organisms
  11. 11Define systematicsThe study of the evolutionary relationships between organisms (currently being redefined through the use of DNA)
  12. 12Describe the relationship between the taxa: domain, kingdom, phylum, class, order, family genus, speciesBasic classification categories ordered from most inclusive (most diverse) to least inclusive (least diverse)
  13. 13What are the three domain classifications of living things?Archaea & Eubacteria (Prokaryotic Cells)
    Eukaryotic Cells
  14. 14Archaea live in what type of environment?Extreme environments (hot springs, salt ponds)
  15. 15Eubacteria live in what types of environments?Most surfaces and environments (gut of animals, soil, ponds etc.)
  16. 16Ribosomal RNA has been used to assist in what?The classification of Eukaryotic, Eubacteria and Prokaryotic cells
  17. 17What are features of kingdom Protista?Eukaryotic- True nucleus.
    Mostly unicellular (protozoan), some multicellular algal forms (kelp).
    Requires oxygen, reproduce asexually, most have cilia and flagella
  18. 18What are features of kingdom Fungi?Multicellular, heterotrophic, cell walls composed of Chitin, spore propagation, mycelial branching.
  19. 19What are features of kingdom Plantae?Multicellular, Autotrophic (photosynthetic), tissue differentiation, cell walls (cellulose), non-motile, meiosis, fertilization, diploid and haploid life phases
  20. 20What are features of kingdom Animalia?Multicellular, heterotrophic, meiosis, fertilization, tissue differentiation, no cell walls, motile, cilia and flagella with protein tubulin (cytoplasmic protein)
  21. 21Explain binomial nomenclature."Two name" system AKA scientific name, genus (Capitalized) species (lower case) and underlined. Pisum sativum.
  22. 22How many electrons complete the first three rings of an outer shell?First: 2
    Second: 8
    Third: 8
  23. 23What are the most common elements of living things?SPONCH
    Sulfur, Phosphorus, Oxygen, Nitrogen, Carbon, and Hydrogn
  24. 24What are the four most abundant elements?Carbon, Hydrogen, Oxygen and Nitrogen
  25. 25What elements make up carbohydrates?CHO
  26. 26What elements make up proteins?CHONS
  27. 27What elements make up lipids?CHO and P in membranes
  28. 28What elements make up Nucleic Acids?CHONP
  29. 29What is the difference between and atom and an ion?Atom- electrically neutral, protons=electrons
    Ion- Cation, positive charge, protons>electrons
    Anion, negative charge, protons
  30. 30Explain an Ionic bondA chemical bond which exchanges electrons to have a full opposite charge (NaCl)
  31. 31Explain covalent bondingCovalent bonds share electrons to complete the outer shell (H2O)
  32. 32Be aware of polyatomic ionsPO43-, NO31-, SO42-
  33. 33Describe a polar moleculeA covalent but unequal sharing of electrons between two atoms causes a slight charge. H2O is an example in which the Oxygen becomes negatively charged while the Hydrogen is positively charged.
  34. 34Explain a non-polar moleculeA non-polar molecule shares electrons equally resulting in no charge.
  35. 35What is the nature of a hydrogen bond?A hydrogen bond is an electrostatic attraction in which a slightly positively charged hydrogen molecule is attracted to a slightly negatively charged molecule.
    Individually weak but collectively strong.
