Term
Fact
Definition
a measured observation
Term
law
Definition
a consistent pattern
Term
theory
Definition
ideas that unify many and diverse phenomena of nature
Term
inertia
Definition
velocity stays the same
Term
Field Force
Definition
the space between objects pulling together from a distance.
Term
potential energy
Definition
energy thats not yet moving or still can move.
Term
1st law of thermodynamics
Definition
energy cant be created/destroyed, just transferred from one type of energy to another.
Term
Heat
Definition
random molecular motion
Term
Self-assembly
Definition
Tendancy of certain objects to undertake a nonrandom arrangement due to field force interactions
Term
emergent property
Definition
any property of a system that results from the arrangement of the systems parts
Term
ordered arrangement
Definition
when the parts of a system are arranged in a pattern
Term
self-organization
Definition
a systems parts interact in a way that results in these parts taking on a now random arrangement
Term
process
Definition
when a processor alters inputs, such that outputs are different than other outputs
Term
Performance
Definition
the result of two or more processes being linked together by regulatory connections
Term
sensor
Definition
any device that adjusts a processors rate as a response to detecting some change in conditions
Term
input-based regulation
Definition
when one processor is input-limited and teh actions of another processor influences the supply of the limited output
Term
counter-acting response
Definition
when a sensor that detects change initiates rate adjustments that reverse the trend
Term
co-acting response
Definition
when a sensor that detects change initiates rate adjustments that maintain or accelerate the trend.
Term
homeostasis
Definition
act of maintaining similar conditions despite constant (disruptive) functuations.
Term
information
Definition
what any arrangement that can cope for some activity
Term
genome
Definition
a set of info that, in total, has sufficient info to guide the development of a reproductively competent organism.
Term
gene
Definition
a single instruction within a genome.
Term
genotype
Definition
an organisms specific constitution of genetic information
Term
phenotype
Definition
the performing (active) part of an individual organism, which is generally thought of as an organisms body.
Term
shape-performance trade off
Definition
motion that because an organism has a certain shape, it cant be great at doing everything.
Term
asexual reproduction
Definition
the production of offspring by a single parent, where, in the absense of errors, the parents genotpe is passed intact to each offspring.
Term
sex
Definition
when genetic information from more than one individual is combined into a single individual
Term
gamete
Definition
a haploid (single set) cell is capable of rusing with another gamete-typically of the opposite sex-to form a diploid cell
Term
anisogamy
Definition
when a sexual population produces 2 distinct types of gametes - generally a small mobile gamete (male) and a larger nutrient laden gamete (women)
Term
ploidy level
Definition
the number of genomes contained within a cell
Term
biological species concept
Definition
an individual organisms of the opposite sex are members of the same species, if and only if, they recover eachother of potential mates (hence may attempt to mate)
Term
trophic level
Definition
a species position in an energy food chain (organic matter used as fuel)
Term
gross production efficiency
Definition
the efficiency with which biomass consumed from one trophic level is converted into biomass at the next trophic level
Term
niche
Definition
the set of conditions (based on each species' set of requirements) under which a species can maintain a viable population
Term
carrying capacity
Definition
the maximum sustainable population size for each species within a community.
Term
gene pool
Definition
the entire genetic constitution of a sexual population
Term
mutation
Definition
the modifications of a genotype within an individual cell.
Term
biological evolution
Definition
the 2-step process by which descent w/modification followed by persistence across generations.
