WGU C190 PRE ASSESSMENT EXAM 2026
REVIEW SCRIPT SOLVED QUESTIONS
ACCURATE
◉ Speciation Event. Answer: A lineage-splitting event that produces two
or more separate species.
◉ Phylogenetic Event. Answer: The evolutionary development and
history of a species or higher taxonomic grouping of organisms. Also
called phylogenesis. The evolutionary development of an organ or other
part of an organism
◉ Homology Event. Answer: Shared trait among species
◉ Mutation. Answer: A Mutation occurs when a DNA gene is damaged
or changed in such a way as to alter the genetic message carried by that
gene.
◉ Gene Flow. Answer: is the transfer of alleles or genes from one
population to another. Migration into or out of a population may be
responsible for a marked change in allele frequencies (the proportion of
members carrying a particular variant of a gene).
, ◉ Genetic Drift. Answer: is the change in the frequency of an existing
gene variant (allele) in a population due to RANDOM sampling of
organisms. Ex. Earthquake or disaster
◉ Artificial Selection. Answer: The breeding of plants and animals to
produce desirable traits
◉ Krebs Cycle/Citric Acid Cycle. Answer: release stored energy through
the oxidation of acetyl-CoA derived from carbohydrates, fats, and
proteins into carbon dioxide and chemical energy
◉ Calvin Cycle. Answer: is the set of chemical reactions that take place
in chloroplasts during photosynthesis.
◉ Electron Transport Chain. Answer: A group of compounds that pass
electron from one to another via redox reactions coupled with the
transfer of proton across a membrane to create a proton gradient that
drives ATP synthesis. (Produces most ATP)
◉ Glycolysis. Answer: The process in cell metabolism by which
carbohydrates and sugars, especially glucose, are broken down,
producing ATP and pyruvic acid.
