  1. Indirect evidence for the existence of an organism proceeded direct fossil evidence of the organism itself occurred in what two groups of organisms?
    Animals & eukaryotes
  2. What are the two tissue types (germ layers) that cnidaria possess?
    Ectoderm & endoderm
  3. Humans are (select all that apply):
    A) Bilaterians
    b) multicellular
    c) Apes
    d) tetrapods
    e) in the Archaea domain
    A, B, C, & D
  4. Give that fungi are heterotrophic, how do they obtain carbon.
    Through organic compounds
  5. ________________ is the fusion of the cytoplasms of two parent mycelia.
  6. True or false (if false, provide the correct information):
    During plasmogamy the nuclei contributed by parent mycelia fuse.
    FALSE. They fuse during karyogamy
  7. True or false (if false, provide the correct information):
    Karyogamy leads to the production of diploid cells.
  8. What is the name of the process by which sponges feed? Describe the process in 1-2 sentences.
    FILTER FEEDING. Particle-filled water is drawn in through the pores of sponges. The particles become trapped within mucous lining the interior surfaces and the rest of the water is expelled through a hole at the top of the sponge.
  9. True or false (if false, provide the correct information):
    The endoderm becomes the skin and nervous tissue.
    FALSE. Ectoderm.
  10. Provide three characteristics of cnidaria.
    • (more than three are listed below for studying purposes)
    • 1) They are animals
    • 2) They are in the Eukarya domain
    • 3) They are carnivorous
    • 4) They digest their pre in a gastrovascular cavity
    • 5) They areeumetazoans
    • 6) They have ectoderm and endoderm
    • 7) They do not have mesoderm
    • 8) they date to 680 million years ago
  11. _________________ is the name for the animal clade with true tissues
  12. List three of the four characteristics of the Chordata.
    • 1) They have a dorsal, hollow nerve cord
    • 2) they have a notochord
    • 3) they have a muscular post-anal tail
    • 4) they possess pharyngeal slits
  13. List two lineages of mammals that do not lay eggs
    • 1) Marsupials
    • 2) Eutherians
  14. Define the difference between ectothermic and endothermic (in 1-2 sentences).
    Animals that are ectothermic do not use metabolic functions to regulate their internal body temperature; they absorb external heat (eg, from the sun). Animals that are endothermic can and do regulate internal body temperature through metabolic functions.
  15. True or false (if false, provide the correct information):
    Commensalism describes a close relationship between organisms in which both of the organisms benefit from the relationship.
    FALSE. Mutualism.
  16. True or false (if false, provide the correct information):
    Mycorrhizae relationships are mutually beneficial relationships between fungi and plant roots
  17. What benefit do plants receive from fungi in mycorrhizal relationships?
    Fungi help plants obtain nutrients from the soil by forming large networks of mycelial around the plants roots
  18. __________________ are a type of fungi that live inside leaves or other parts of plants and make toxins that deter animals from eating the plant.
  19. How did the evolution of the amniotic egg further the colonization of land by animals (in 1-2 sentences)?
    It untethered animals from needing a water source for reproduction because the amniotic egg protected the embryo and prevented it from dehydration.
  20. The following are true of amniotic eggs (select all that apply):
    A) A chorion membrane that works with the allantois in the exchange of gas
    B) An allantois that creates a waste cavity for waste products produced by the embryo
    C) a exterior shell that is frequently hard
    D) The embryo within the egg undergoes plasmogamy and karyogamy
    E) The life cycle of the developing embryo is known as the alternation of generations
    A, B, C
  21. Put the following terms in order from most to least inclusive:
    1) Apes
    2) Domain
    3) Vertebrates
    4) Mammals
    5) Eutherians
    2, 3, 4, 5, 1
