Being able to survive and reproduce
What is fitness?
100
This occurs because traits are often heritable and organisms compete to survive
What is natural selection?
100
When alleles are transferred between populations due to immigration
What is gene flow?
100
The first details relatedness, but the second also incorporates time
What are cladograms and phylogenetic trees?
100
This is required to have two different species
What is reproductive isolation?
100
What are the smallest units of life?
What are cells?
200
What term describes the process by which individuals with certain heritable traits are more likely to survive and reproduce in a given environment, leading to the accumulation of advantageous traits over successive generations?
What is natural selection?
200
If an organism has a more favorable trait, then it will be more likely to _______ and _______.
If an organism has a more favorable trait, then it will be more likely to survive and reproduce.
200
When a cataclysm occurs the remaining allele frequencies are different than they were before the event
What is bottleneck effect?
200
This represents speciation events and common ancestors
What is a node?
200
What is the term for the reproductive isolation mechanism where different species are physically unable to mate due to differences in genitalia or other reproductive structures?
What is mechanical reproductive isolation
200
What biome displays the highest amounts of biodiversity?
What are Tropical Rainforest?
300
An environmental factor that impacts whether an organism can survive and reproduce. ______________ pressure
What is selective pressure?
300
The two equations of HW equilibrium involve these terms and each of them mean . . .
What is p for dominant allele frequency, q for recessive alle frequency, p2 for homozygous dominant frequency, 2pq for heterozygous frequency, and q2 for homozygous recessive frequency?
300
When environments are similar they lead to the development of similar traits in two different lineages and the traits are called this
What is convergent evolution and analogous traits?
300
This lineage is the least closely related member of the clade
What is the outgroup/basal taxa?
300
The fur tree's pollen cannot physically attach to the pine tree's cone
What is an example of mechanical isolation?
300
First team to start singing a song (30 seconds) gets the points

400
When the extremes of a trait are both equally selected for, this occurs
What is disruptive selection?
400
- Large population size
- No gene flow (no migration)
- No mutations
- Random mating
- No natural selection
1.What are the five conditions that must be met for a population to be in Hardy-Weinberg equilibrium?
400
These structures exist between organisms who share those types of ancestors
What are homologous traits and common ancestors?
400
These four things can be used to create cladograms
What are DNA, morphology, biogeography, and fossils?
400
First team to have ALL members stand up get the points

What is the difference in these symbiotic relationships?
One is commensalism, and the other is parasitism.

CURVE BALL
The 4 Macromolecules are __.
What are Carbohydrates, lipids, proteins, and nucleic acids?
500
____-_____ equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
What is Hardy Weinberg?
500
What term describes the evolutionary process by which unrelated species evolve similar traits due to similar environmental pressures, often leading to analogous structures such as wings in birds and bats?"
What is convergent evolution?
500
What is the difference between the Ray-finned fish and the Amphibians?
What is four Limbs
500
a theory that explains how eukaryotic cells may have evolved from simpler prokaryotic cells that merged together. It states that multiple cells joined together into one, and began to live in symbiotic relationships.
What is Endosymbiotic Theory?
500
Which animal would have an immediate major change in population in the grasshopper population went extinct?
What is the rat species?
