100
This is the term for a group of the same species living together in the same geographic area.
What is population
100
A change in allele frequency over time is called
What is evolution
100
This is the term for a population of individuals whose members can interbred and produce fertile offspring.
What is a biological species
100
This is the theory that proposes that most species will exhibit little net evolutionary change for most of their geological history, then have short bursts of rapid change.
What is punctuated equilibrium
100
bacteria usually reproduce by this method, which results in 2 identical cells
binary fission
200
The ability of an organism to survive, and in particular, produce offspring is known as
What is fitness
200
The leopard frog mates in the spring but the bull frog mates in the summer. What is this an example of?
What is temporal isolation
200
this is the total collection of alleles in a population
What is gene pool
200
This is the spreading and diversification of organisms that occur when they colonize a new habitat.
What is adaptive radiation.
200
Relative dating uses a fossils position in the layers of this type of rock to determine the fossils age.
What is sedimentary
300
Penicillin and other beta lactam antibiotics work by destroying this part of bacteria
What is cell wall
300
The response of a population to environmental pressure so that advantageous traits become more common over time is known as
What is adaptation
300
Giraffes necks did not stretch to reach food. Rather, those with long necks thrived while those with short necks died. This differential survival in response to environmental pressure is known as
Natural selection
300
This unstable element decays into lead by emitting energetic particles and it is used to date rock.
What is radioactive uranium
300
This is the movement of alleles from one population to another which can increase diversity.
What is gene flow
400
Over using antibiotics, not finishing the entire course of antibiotics and the fact that bacteria divide (and can potentially have a mutation) every 20 to 30 minutes have all lead to this.
What is antibiotic resistance
400
Of all the mechanisms that lead to a change in allele frequency, only this one results in adaptation.
What is natural selection
400
This is a type of genetic drift that happens when a population is suddenly reduced to a small number of individuals and alleles get lost as a result.
What is bottleneck effect
400
This experiment simulated the conditions thought to be present on the early earth. It supported the idea that organic molecules could have formed due to Earths conditions.
What is Urey Miller
400
This is the term for preventing gene flow between members of different species. Mechanical, Temporal, Behavioral and Ecological are examples.
What is reproductive isolation.
500
Human babies are an example of this type of selection. Those with low birth weights and those with high birth weights are at higher risk for death. Instead the middle of the range is favorable.
What is stabilizing selection.
500
Because they change allele frequency but do not lead a population to become more adapted to their environment, mutation, gene drift and gene flow are all considered this.
What is non adaptive evolution
500
A population of manatees has 5 different alleles, A,B,C,D and E, of a certain gene. A drunk boat driver tears through the water killing 90% of the population. Those remaining are all homozygous for allele B. This is an example of
What is bottleneck effect. (Genetic drift or evolution are also acceptable answers)
500
At the end of this period, there was the largest extinction event in history with a loss of 95% of species.
What is the permian
500
These are the 5 assumptions of Hardy-Weinberg
What are: No mutation, no natural selection, no genetic drift, no gene flow and random mating
