Macroevolution - ANSWER Evolutionary change above the species level.
Ecological species concept - ANSWER identifies species in terms of their ecological niches, focusing on
unique adaptations to particular roles in a biological community
Postzygotic - ANSWER Barriers that prevent the hybrid zygote from becoming a fertile adult.
The theory of gradualism - ANSWER Profound geological changes took place through the cumulative
effect of slow but continuous processes identical to those currently operating
Prezyogotic - ANSWER Reproductive isolation
Artificial selection - ANSWER Breeding organisms with specific traits in order to produce offspring with
identical traits.
Microevolution - ANSWER Change in allele frequencies in a population over generations.
, Biological species concept - 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 - 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 - ANSWER Characters (such as height) are those that vary along a continuum within a
population.
Homologous - ANSWER Structures in different species that are similar because of common ancestry.
Exoenzymes - ANSWER Hydrolytic enzymes released by fungi into their surroundings
Chitin - ANSWER Component of fungi cell walls
Parasites - ANSWER Absorb nutrients from living hosts
Saprobes - ANSWER Absorb nutrients from dead matter
Mycellium - ANSWER An interwoven mass of fungal hyphae that surrounds the material on which the
fungus feeds
Septa - ANSWER An incomplete cross-wall dividing hyphae into separate cells
Coenocytic cells - ANSWER Cells that lack septa
