What does HIV and AIDS stand for?
Human immunodeficiency virus and acquired immune deficiency syndrome
100
What is special creation and anagenesis?
Organisms were placed here and changed over time
100
What is Bergman's rule?
Within a species, in a colder region, warm blooded animals are bigger
100
What is homology?
Similarity due to shared ancestry
100
What does homoplasious mean?
Similar but not because of inheritance from a common ancestor
200
Which protein on a HIV virion binds to CD4 and coreceptor on host cell?
gp120
200
What is anagenesis?
Change within a group in a phenotype over time
200
What are vestigial structures?
Rudimentary version of a body part that has a function in other, closely allied species
200
What is natural selection?
Differential survival and/or reproductive success of individuals caused by differences in their phenotypes
200
What is the difference between cladograms and phylograms?
Cladogram: branching order only Phylogram: distances
300
HIV's RNA genome, _______ _____________, _________, and _________ enter host cell
Reverse transcriptase, integrase and protease
300
What is cladogenesis?
Generation of new clades or groups
300
What is microevolution and macroevolution?
Microevolution is evolution from generation to generation, spans of generation Macroevolution: evolution of geographical timespans
300
What is evolution by natural selection?
Change in the mean in a population over generations, involves genetics
300
What are synapomorphies?
Shared derived characters
400
What is the order of DNA transcription in regards to HIV virions?
RNA ---> (reverse transcriptase) DNA ---> mRNA ---> protein
400
What is speciation?
Lineages split and diverge
400
What is the law of succession?
Organisms in a geographical area are similar to the fossils in that geographic area
400
What is fitness?
A measure of the ability to survive and reproduce. Relative, not absolute.
400
What is the difference between plesiomorphy and apomorphy?
Plesiomorphy: ancestral character Apomorphy: derived character
500
Which immune system cells carry both CD4 and CCR5 on membranes and are vulnerable to HIV?
Macrophage, effector helper T cells, and memory helper T cells
500
What is a cline?
A gradual change over space
500
What are transitional forms?
Links between new and old
500
What does homologous mean?
Inherited from a common ancestor
500
What is a mutation?
A heritable change in the genetic material that is not due to genetic recombination
