  1. HOW MANY PHYLUMS ARE THERE?
    NINE. 

    • 1. Annelida
    • 2. Anthropoda
    • 3. Chordata [HUMANS]
    • 4. Cnidaria
    • 5. Echinodermata
    • 6. Mollusca
    • 7. Nematoda
    • 8. Platyhelminthes
    • 9. Porifera
  2. Phylum Porifera - WHO?
    The Sponges
  3. Phylum Coelenterata WHO?
    The Coelenterates: jellyfish, hydras, corals
  4. Phylum Platyhelminthes WHO?
    The Flatworms: planaria, tapeworms

    Symmetry: Flatworms have bilateral symmetry and they have a definite head and tail region.
  5. Phylum Nematoda WHO?
    The Roundworms

    Symmetry: Bilateral symmetry with an anterior end and a posterior end.
  6. Phylum Annelida WHO?
    The Segmented Worms: earthworm, leech, sandworm.

    Symmetry: Bilateral; anterior and posterior ends; dorsal and ventral surfaces.

    Segmented both internally and externally
  7. Phylum Arthropoda WHO
    The Arthropods: insects, spiders, crustaceans

    Symmetry: Bilateral
  8. Phylum Mollusca WHO?
    The Mollusks: clams, snails, oysters, octopus

    Symmetry: bilateral
  9. Phylum Echinodermata WHO?
    The Echinoderms: sea stars, sea urchins

    Symmetry: Radial
  10. Phylum Chordata WHO?
    The Chordates: fish, reptiles, amphibians, birds, mammals
  11. How Do Biologists Characterize Populations?
    • unstructured population
    • all individuals are subject to the same general ecological pressures.

    rates of growth, reproduction, and mortality are roughly the same for all individuals.

    EX: bacterial colony 

    • structured populations
    •  individuals can differ from one another in ways that make some individuals more susceptible to mortality or more likely to reproduce than others.

    EX: insects, sea turtles, trees, and fish.

    In these cases, mortality is often much higher for younger (and/or smaller) individuals.

    Reproduction is often delayed until individuals are older (and/or larger).
  12. LOGISTIC GROWTH...COLUMNS AND FORMULAS.
  13. DEFINE r SELECTIVE SPECIES
    EX: FROG 

    • LOTS OF OFFSPRING
    • MANY WILL NOT SURVIVE. 
    • LITTLE PARENTING
  14. DEFINE K SELECTIVE SPECIES
    SALMANDER OR HUMAN

    • FEW OFFSPRING
    • WILL SURVIVE LONGER
    • LOTS OF PARENTING
  15. WHAT COMES FIRST EXPERIENTIAL OR LOGISTIC GROWTH?
    EXPERIENTIAL THEN LOGISTIC. 

    LOGISTIC HAS EQUILIBRIUM WITH THE "K" FACTOR.
  16. WHAT IS THE COLUMNS AND FORMULAS FOR EXPONENTIAL GROWTH?
    • N= POPLUATION
    • r = B-D/N
    • (IN THIS EXAMPLE r WAS SOLVED, IT'S .3)
