  • Name one advantage to sexual reproduction.
    genetic diversity (differences due to a combo of genes from both parents)
  • Binary fission is how bacteria reproduces asexually. What is true about asexual reproduction regarding the number of parents and offspring?
    One parent creates genetically identical offspring to the parent- 2 total
  • Biotic organisms must meet the 9 characteristics that all living things share. Which of the following does NOT belong? DNA, cell (s), movement, obtain and use energy, adapt to environment, maintain homeostasis, excrete waste.
    movement- moving from one place to another
  • Prokaryotes are...(describe them in 3 statement/characteristics).
    unicellular, no nucleus, very small, simple, reproduce asexually (ex: Eubacteria or Archaebacteria kingdoms)
  • Name one disadvantage to asexual reproduction.
    NO genetic diversity- offspring identical to parent
  • In a grocery store items are classified how?
    Similar items can be found on the same aisle.
  • What is the purpose of a dichotomous key?
    identify an unknown organism
  • In order for 2 organisms to be most closely related, their taxons would...?
    They would have many taxon levels in common to show similar characteristics
  • DNA is found in the cells of all living things. This genetic material contains the...
    blueprint for life
  • Which of the following is NOT a biotic factor? pavement, a bush, grass, ants
    pavement- (rock-concrete)
  • Organisms in this kingdom are all autotrophic and can reproduce both sexually and asexually.
    Plant (Plantae)
  • What are the rules for correctly writing the scientific name?
    Capitalize the Genus; do NOT capitalize the species; underline the whole thing OR put it in italics
  • A consumer, also called a heterotroph does NOT make their own food. How do they get the energy they need to fuel life's processes.
    Eat others, they reply on hunting and such to consume/eat other organisms
  • The Genus and the Species make up the organism's?
    scientific name
  • How do autotrophs get their food?
    Go through photosynthesis, use light energy from the Sun, to make their own food.
  • If an organism is a heterotroph, eukaryote, can move from place to place and reproduce sexually, name that kingdom.
    Animal (Animalia)
  • What function does flagella serve for prokaryotic organisms?
    for movement
  • Name one advantage to asexual reproduction.
    quick process, no mate required, reproduce often and easily
  • In a dichotomous key, what step do you always start back on after identifying an organism?
    Step 1
  • Organisms that live in the deepest depths of the ocean where it is really cold must be able to maintain a stable internal environment inside their bodies. This is an example of?
    homeostasis
  • Eukaryotes all have DNA inside the?
    nucleus
  • Name one disadvantage to sexual reproduction.
    slow process, mate require, reproduce less often
  • What is the purpose of a decomposer like fungi and bacteria?
    To rid the Earth of waste, so that it is not buried in it. They break down dead things.
  • How an organism is organized is... (hint: # of)
    unicellular or multicellular
  • Define a cell.
    Basic unit of life; contains all materials necessary for life; membrane-covered structure
