  1. Fact
    A measured property of the surrounding world. Like the weight of an object. A measured observation.
  2. Law
    a regular pattern of occurrence in Nature (e.g., the universal law of gravitation).
  3. Theory
    a general idea that aids in conceptually unifying , explaining, many and diverse phenomena of nature.
  4. Inertia
    The tendency for the velocity of an object to stay the same.
  5. Field Force
    the push or pull that an object experiences as the result of colliding with another object.
  6. Potential energy
    the energy associated with the potential- due to the presence of an unequal distribution of forces-
  7. 1st law of thermodynamics
    energy can neither be created or destroyed. It can only be transformed from one type of energy to another. PE to KE or KE to PE
  8. heat
    random molecular motion
  9. self-assembly
    the tendency of certain objects, due to field force interactions, to take on and or stay in nonrandom arrangement.
  10. emergent properties
    any property property of a system that results from a system's parts
  11. ordered arrangement
    when the parts of a system are arranged in a pattern--nonrandom arrangement.
  12. self-organization
    a system's parts interact in a way that results in these parts taking on nonrandom arrangement.
  13. Process
    that which occurs when something (a processor) alters inputs, such that outputs are different then inputs.
  14. Performance
    that which results from 2 or more processes being linked together by regulatory connections.
  15. Sensor
    any device that adjusts a processor's rate as a response to detecting some change in condition.
  16. input-based regulation
    whenever one processor is input limited, and the actions of another processor influences the supply of limiting input.
  17. counter-acting response
    when a sensor that detects some trend of change initiates rate adjustments that act to reverse the trend.
  18. co-acting response
    when a sensor that detects some trend of change initiates rate adjustments that act to maintain or even accelerate the trend.
  19. homeostasis
    the act of maintaining similar conditions despite constant disruptive fluctuations.
  20. information
    What any arrangement that can code for some activity has
  21. genome
    a set of genes that has enough information to guide the assembly of a fully functional organism.
  22. phenotype
    The shown traits of an individual. Active part of an individual organism.
  23. gene
    a single instruction within a genome
  24. genotype
    genetic information of an individual. The specific allele makeup of an individual.
  25. shape-performance tradeoff
    Organisms have specific traits and therefore cannot be good at everything. An organisms shape makes certain activities possible at the cost of not being able to perform other activities.
  26. asexual reproduction
    to produce offspring with a single parent. Without error, the parents genotype is passed intact to their offspring.
  27. sex
    when genetic info from more then one individual is combined into a single individual
  28. gamete
    haploid cell capable of fusing with another gamete, sperm and egg
  29. anisogamy
    The presence of 2 gamete types (egg and sperm)
  30. ploidy level
    number of genomes contained within a cell
  31. biological species concept
    • organisms are apart of the same species if
    • 1. they recognize each other as portential mates (attempt to mate) .
    • 2. they can produce viable offspring
  32. trophic level
    a species position in an energy food chain
  33. niche
    the set of conditions under which a species can maintain a viable population
  34. gross production efficiency
    the efficiency from which the biomass consumed at one trophic level is converted into biomass at the next trophic level
  35. carrying capacity
    the maximum sustainable population size for each species within a community.
  36. gene pool
    the entire genetic constitution of a sexual population
  37. mutation
    the modification of a genotype within an individual cell.
  38. biological evoloution
    the two step process of descent with modification followed by persistence across generations.
  39. natural selection
    when a modified type is caught in a reproductive race with an ancestral type. The outcome of the race depends on performance ability.
  40. genetic drift
    when a modified type is caught in a reproductive race with an ancestral type and the outcome of the race is affected by chance occurrences.
  41. phylogeny
    the pattern of relatedness among different species, where any two species relatedness depends on how recently they branched from a common ancestor.
