Cards

Term
Process
Definition
that which occurs when something (a processor) alters inputs, such that outputs are different than inputs
Term
Self-Organization
Definition
a system's parts interact in a way that results in these parts taking on a non-random arrangement
Term
Gene
Definition
a single instruction within a genome
Term
Shape-Performance Tradeoff
Definition
the notion that because an organism has a particular shape (at any point during its life) it cannot be great at doing everything. Any shape makes certain activities possible, but at the cost of not being the best shape to perform well in other ways
Term
Inertia
Definition
the tendency for the velocity of any object to stay the same
Term
Law
Definition
a regular pattern of occurence in Nature
Term
Field Force
Definition
the push and pull that an object experiences as the result of an interaction with another object at a distance
Term
Trophic Level
Definition
a species' position in an energy food chain. 1st level: species use the sun as energy source. 2nd level: species acquire their needed supply of usable energy by feeding on 1st level species and so on.
Term
Genome
Definition
a set of information that, in total, has sufficient information to guide the development of a reproductively competent organism
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
Performance
Definition
that which results from 2 or more processes being linked together by regulatory connections
Term
Ordered Arrangement
Definition
when the parts of system are arranged in a pattern-that is, they have a non-random arrangement
Term
Self-Assembly
Definition
the tendency of certain objects, due to field force interactions, to take on and/ or stay in a non-random arrangement
Term
Information
Definition
what any arrangement that can code for some activity has (something that has information can be interpreted, where the interpretation is the conversion of the coded activity into the activity)
Term
1st Law of Thermodynamics
Definition
energy can neither be created nor destroyed, only transformed from one type of energy to another
Term
Heat
Definition
random molecular motion
Term
Emergent Property
Definition
any property of a system that results from the arrangement of the system's parts
Term
Counter-acting response
Definition
when a sensor that detects some trend of change initiates rate adjustments that act to reverse the trend
Term
Sensor
Definition
any device that adjusts a processor's rate as a response to detecting some change in conditions
Term
Sensor
Definition
any device that adjusts a processor's rate as a response to detecting some change in conditions
Term
Input-based regulation
Definition
whenever 1 processor is input limited and the actions of another processor influences the supply of the limiting input
Term
Co-acting response
Definition
when a sensor that detects some trend of change initiates rate adjustments that act to maintain or even accelerate the trend
Term
Ploidy Level
Definition
the number of genomes contained within a cell
Term
Gene Pool
Definition
the entire genetic constitution of a sexual population (all the genetic information contained all the genotypes of the individuals that make up the population)
Term
Mutation
Definition
a modification of the genotype within an individual cell. Multicelluar organisms: somatic cell or germ cell
Term
Biological Evolution
Definition
the 2 step process of descent with modification followed by persistence across generations
Term
Natural Selection
Definition
whenever a modified type is caught in a reproductive race with an ancestral type, and the outcome of the race is affected by differences in performance ability
Term
Genetic Drift
Definition
whenever a modified type is caught in a reproductive race with an ancestral type and the outcome of the race is affected by chance occurences
Term
Homeostasis
Definition
the act of maintaining similar conditions despite constant disruptive fluctuations
Term
Theory
Definition
a general idea that aids in conceptually unifying, hence explaining, many and diverse phenomena of Nature
Term
Potential Energy
Definition
energy associated with the potential-due to the presence of an unequal distribution of forces-of an object to increase its velocity, or accelerate, in the future
Term
Fact
Definition
a measured property of the surrounding world; measured observation (perspective of the observer)
Term
Anisogamy
Definition
when an sexual population produces 2 distinct types of gametes-generally a small mobile gamete (male) and a larger nutrient-laden gamete (female)
Term
Gamete
Definition
a haploid cell capable of fusing with another gamete-typically of the opposite sex-to form a diploid cell
Term
Sex
Definition
when genetic information from more than 1 individual is combined into a single individual
Term
Sex
Definition
when genetic information from more than 1 individual is combined into a single individual
Term
Sex
Definition
when genetic information from more than 1 individual is combined into a single individual
Term
Sex
Definition
when genetic information from more than 1 individual is combined into a single individual
Term
Sex
Definition
when genetic information from more than 1 individual is combined into a single individual
Term
Genotype
Definition
an organism's specific constitution of genetic information
Term
Asexual Reproduction
Definition
the production of offspring by a single parent, where, in the absence of errors the paren'ts genotype is passed intact to each offspring
Term
Phylogeny
Definition
the pattern of relatedness among different species, where any 2 species relatedness depends on how recently they branched from a common ancestor
Term
Phenotype
Definition
the performing (active) part of an individual organism, which is generally thougth of as the organism's body and specific features of an individual's body
Term
Biological Species Concept
Definition
2 individual organisms of the opposite sex are members of the same species, if and only if, they recognize each other as potential mates; and if they mate they produce a viable offspring; the largest unit of populations within which the mixing genetic information through sexual reproduction occurs and should occur
