GCU BIO-182 EXAM I QUESTIONS &
ANSWERS 100% SOLVED
Aerobes - ANSWERorganisms that require oxygen to live
Allopatric Speciation - ANSWERgene flow is interrupted when a population is divided
into geographically isolated subpopulations
Pilobolus - ANSWERa zygomycete that uses a light spot to aim its sporangia toward
a good food source
Plasmogamy - ANSWERthe fusion of the cytoplasms of two parent mycelia
Saprophytes - ANSWERa plant, fungus, or microorganism that lives on dead or
decaying organic matter
Septate Hyphae - ANSWERhyphae whose cells are divided by septa (septum)
Soredia - ANSWERin lichens, a small cluster of fungal hyphae with embedded algae
Anaerobes - ANSWERorganisms that do not require oxygen to live
Artificial Selection - ANSWERprocess of deliberately selecting and breeding
individuals with desired traits
Biological Species Concept - ANSWERdefining a species as a population whose
members have the potential to interbreed in nature and produce viable, fertile
offspring
Stabilizing Selection - ANSWERThis type of selection occurs when both the largest
and smallest individuals contribute fewer offspring to the next generation
Sympatric Speciation - ANSWERSpeciation that occurs in populations that live in the
same geographic area
Speciation - ANSWERFormation of a new genetically distinct species
Gradualism - ANSWERProfound geological changes took place through the
cumulative effects of low but continuous processes identical to those currently
operating
Microevolution - ANSWERCharacters (such as height) are those that vary along a
continuum within a population
, Creationism - ANSWERviewpoint on the origin of life which references a divine
creator
Disruptive Selection - ANSWERThe largest and smallest individuals contribute more
offspring than those at the middle
Ecological Species Concept - ANSWERDefining a species based on its role in the
biological community and the set of environmental resources used
Eukaryotes - ANSWERSingle or multi-cellular organism with membrane-bound
organelles
Evolution - ANSWERScientific concept that all life descended from a common
progenitor
Gene Flow - ANSWERMovement of alleles among populations
Genetic Drift - ANSWERAllele frequencies fluctuate unpredictably from one
generation to the next
Linnaeus - ANSWERDeveloped binomial nomenclature used to name and classify
organisms
Macroevolution - ANSWEREvolutionary changes that result in speciation
Phylogeny - ANSWERStudy of adaptive changes within a population
Population - ANSWERThis is the smallest entity that can evolve according to
evolutionary theory
Postzygotic - ANSWERDoes not develop into a viable, fertile adult, or hybrids that
are vigorous but sterile
Prezygotic - ANSWERSpatial isolation is an example of this barrier
Prokaryotes - ANSWERSingle-celled organism lacking membrane-bound organelles
Quantitative - ANSWERClassification of organisms based on their evolutionary
history
Amoebozoans - ANSWERA protist in a clade that includes many species with lobe-
or tube-shaped pseudopodia; includes: slime molds, tubulinids, and entamoebas
Heterocysts - ANSWERCells which carry out only nitrogen fixation; these cells are
part of a photosynthetic cyanobacteria
Alveolates - ANSWERhave membrane-enclosed sacs (alveoli) just under the plasma
membrane
