    • Are animals eukaryotic or prokaryotic?
      Eukaryotic
    • Are Animals Multicellular or Unicellular?
      Multicellular
    • Are animals heterotrophs or autotrophs?
      Heterotrophs
    • Do animals have a cell wall?
      No
    • What does an animal do that a plant can't?
      Move
    • Animals reproduce sexually right? With what stage?
      Yes, with a dominant diploid stage.
    • What is a Eukaryote?
      cell that has a nucleus
    • What distinguishes animals as Multicellular?
      Multiple cells
    • What is a Heterotroph?
      An organism that obtains its energy by consuming other organisms.
    • What is a dominant diploid stage in sexual reproduction in animals?
      A dominant diploid stage involves the fusion of gametes from two individuals to produce offspring.
    • What is the difference between haploid and diploid?
      Haploid refers to having one set of chromosomes, while diploid refers to having two sets of chromosomes.
    • What is the most common ancestor to all animal species?
      Choanoflagellates.
    • How long ago did choanoflagellates exist?
      770 million years ago
    • Around 700 million years ago the emergence of what animal specifically occurred?
      Sponges
    • Where did sponges originate from?
      Sponges originate from choanoflagellates which later generated all the other animals.
    • What evidenced the emergence of animals?
      Fossils which mainly consisted of soft-bodied animals.
    • When fossils were discovered, evidencing the emergence of animals, what happened 530 million years ago?
      The Cambrian Explosion happened
    • What is the Cambrian Explosion?
      It is where most of the major animal groups started to appear in the fossil record, a time of rapid expansion of different forms of life on Earth.
    • The Cambrian Explosion
      Increase in diversity especially bilaterian organisms
    • What are bilaterian organisms?
      They are organisms with bilateral symmetry
    • What is bilateral symmetry?
      When the body plan of an animals can be divided along a line that separates the animal's body intro right and left halves that are nearly identical of each other.
    • What may have caused the Cambrian Explosion?
      • possibly because an "arms race"
      • increased atmospheric Oxygen
      • or Hox Genes which just made it easier for animals to evolve new forms
