Evolution
Origins of life: The early atmosphere did not include this gas
What is Oxygen?
This biomolecule contains a polar head and a non-polar tail
A type of interspecies relationship where one organism benefits while the other is unaffected
What is commensalism
This biomolecule contains a phosphate group, a ribose sugar, and a nitrogenous base
What is a nucleotide
When environmental conditions favor the survival and reproduction of individuals with a particular trait
What is natural selection
When animals are derived from the same ancestor species
what is common ancestry?
The type of growth succession that occurs in an ecosystem with no soil or growth substrate
What is primary succession
A type of animal behavior that is not genetic and is easily adaptable
What is learned behavior
These organisms are able to convert chemicals into food
What are chemoautotrophs
The presence of these organelles inside animal cells imply that animals and bacteria have a common ancestor
A type of speciation caused by geographic isolation
What is Allopatric Speciation?
ADP is phsophorylated into ATP in this component of cellular respiration
What is the Electron Transport Chain
This is the major source of genetic variation in asexually reproducing organisms
What are genetic mutations
The introduction of this type of organism can disrupt the trophic levels in an ecosystem and displace native species
What is an invasive species
A change in or response of an organism due to seasonal changes in day light
What is Photoperiodism?
A form of genetic selection where changes in environmental conditions cause one phenotype to replace another
What is Directional Selection?
A type of feedback where the effect of an event causes that effect to increase
What is positive feedback
This type of cell can differentiate into many types of cells when it receives chemical signals from other, differentiated cells
What are stem cells
The removal of this type of organisms from an ecosystem can cause a trophic cascade and ecosystem collapse
What is a keystone species
Hardy-Weinburg: If 9% of the population has recessive blue eyes, what % of the population is hybrid brown eyes? Homozygous for brown eyes?
42% Hybrid
This form of fossil dating gives a specific age for a fossil using radioactivity
What is absolute dating?
This occurs when there is an error in the cell cycle and the reproduction of the cell would result in cancer
What is apoptosis
This part of the neuron assists in signal transduction by insulating the electrical signal that travels down the axon
What is the myelin sheath
This describes the process of nutrient pollution in a water system that results in the overgrowth of sub aquatic vegetation
What is eutrophication
Hardy-Weinburg: If 9% of the population has recessive blue eyes, what % of the population is homozygous for brown eyes?
49% Homozygous Brown
