What is artificial selection?
The physical, observable characterisitics of an organism.
What is the phenotype?
A relationship in which one organism benefits while another is harmed.
What is a parasitic relationship?
Lichen, moss, and other such species that are first to appear in primary succession.
What are pioneer species?
Three main factors that determine the classifications of different biomes.
What are vegetation, temperature, and precipitation?
Structures look that look different, but serve the same function.
What are analogous structures?
Genes that are only expressed in a homogeneous state.
What are recessive genes?
What is primary consumer?
Refers to bodies of water that rich in nutrients.
What is eutrophic?
These water biomes are known to be salt/fresh water and are great nursuries.
What are estuaries?
Offspring that is unable to reproduce is an example of this type of isolation.
What postzygotic isolation?
The mother is heterozygous for a "widow's peak." The father is also heterozygous for a "widow's peak." If widow's peak is dominant, what is the probability their child will have a widow's peak?
What is 75%?
The process in which plants capture nitrogen from the atmosphere and turn it into a usable form.
What is nitrogen fixation?
The term that refers to a biological community and the abiotic factors that affect it.
What is an ecosystem?
This biome is known for having evergreen trees.
What is the boreal forest?

What is overproduction and inheritance?
Different forms of a genes for a single trait?

What is the carbon cycle?
Percentage of the earth that is freshwater.
What is 2.5%?
The deepest zone in a lake/pond that receives the least amount of sunlight.
What is the profundal zone?
When two species evolve in close relationship to each other.
What is coevolution?
In purple people eaters, one-horn is dominant and no horns is recessive. Draw a Punnett Square showing the cross of a purple people eater that is hybrid for horns with a purple people eater that does not have horns. Summarize the genotypes & phenotypes of the possible offspring.
genotypes: 50% Hh and hh
phenotypes: 50% horned and 50% no horns
