BIO 182 Exam 1 questions with correct
answers graded A+ passed
Macroevolution - correct answer ✔✔Evolutionary change above the species level.
Ecological species concept - correct answer ✔✔identifies species in terms of their ecological niches,
focusing on unique adaptations to particular roles in a biological community
Postzygotic - correct answer ✔✔Barriers that prevent the hybrid zygote from becoming a fertile adult.
The theory of gradualism - correct answer ✔✔Profound geological changes took place through the
cumulative effect of slow but continuous processes identical to those currently operating
Prezyogotic - correct answer ✔✔Reproductive isolation
Artificial selection - correct answer ✔✔Breeding organisms with specific traits in order to produce
offspring with identical traits.
Microevolution - correct answer ✔✔Change in allele frequencies in a population over generations.
Biological species concept - correct answer ✔✔Definition of a species as a population or group of
populations whose members have the potential to interbreed in nature and produce viable, fertile
offspring, but are not able to produce viable, fertile offspring with members of other populations.
Population - correct answer ✔✔A local group of organisms belonging to the same species and capable of
interbreeding
According to evolutionary theory, the smallest entity that can evolve is
*evolve over time
, Quantitative - correct answer ✔✔Characters (such as height) are those that vary along a continuum
within a population.
Homologous - correct answer ✔✔Structures in different species that are similar because of common
ancestry.
Gene flow - correct answer ✔✔Movement of alleles into or out of a population due to the migration of
individuals to or from the population
Stabilizing - correct answer ✔✔Natural selection that favors intermediate variants by acting against
extreme phenotypes
Disruptive Selection - correct answer ✔✔form of natural selection in which a single curve splits into two;
occurs when individuals at the upper and lower ends of a distribution curve have higher fitness than
individuals near the middle
Prokaryotic - correct answer ✔✔Single celled organism
Gradualism - correct answer ✔✔Occurrence over a period of time
Eukaryotic - correct answer ✔✔Multicellular organism
Speciation - correct answer ✔✔Genetic changes over time
Phylogeny - correct answer ✔✔Classification of organisms
Anaerobes - correct answer ✔✔Do not require oxygen to live
Creationism - correct answer ✔✔Religious viewpoint
Evolution - correct answer ✔✔Scientific viewpoint
