Biology Vocab Quiz 1

A measured property of the surrounding world. Like the weight of an object. A measured observation.

a regular pattern of occurrence in Nature (e.g., the universal law of gravitation).

a general idea that aids in conceptually unifying , explaining, many and diverse phenomena of nature.

The tendency for the velocity of an object to stay the same.

the push or pull that an object experiences as the result of colliding with another object.

the energy associated with the potential- due to the presence of an unequal distribution of forces-

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

random molecular motion

the tendency of certain objects, due to field force interactions, to take on and or stay in nonrandom arrangement.

any property property of a system that results from a system's parts

when the parts of a system are arranged in a pattern--nonrandom arrangement.

a system's parts interact in a way that results in these parts taking on nonrandom arrangement.

that which occurs when something (a processor) alters inputs, such that outputs are different then inputs.

that which results from 2 or more processes being linked together by regulatory connections.

any device that adjusts a processor's rate as a response to detecting some change in condition.

whenever one processor is input limited, and the actions of another processor influences the supply of limiting input.

when a sensor that detects some trend of change initiates rate adjustments that act to reverse the trend.

when a sensor that detects some trend of change initiates rate adjustments that act to maintain or even accelerate the trend.

the act of maintaining similar conditions despite constant disruptive fluctuations.

What any arrangement that can code for some activity has

a set of genes that has enough information to guide the assembly of a fully functional organism.

The shown traits of an individual. Active part of an individual organism.

a single instruction within a genome

genetic information of an individual. The specific allele makeup of an individual.

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.

to produce offspring with a single parent. Without error, the parents genotype is passed intact to their offspring.

when genetic info from more then one individual is combined into a single individual

haploid cell capable of fusing with another gamete, sperm and egg

The presence of 2 gamete types (egg and sperm)

number of genomes contained within a cell

• 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

a species position in an energy food chain

the set of conditions under which a species can maintain a viable population

the efficiency from which the biomass consumed at one trophic level is converted into biomass at the next trophic level

the maximum sustainable population size for each species within a community.

the entire genetic constitution of a sexual population

the modification of a genotype within an individual cell.

the two step process of descent with modification followed by persistence across generations.

when a modified type is caught in a reproductive race with an ancestral type. The outcome of the race depends on performance ability.

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.

the pattern of relatedness among different species, where any two species relatedness depends on how recently they branched from a common ancestor.
