KSU BIOLOGY 198 EVALUATION EXAM 2026 QUESTIONS
AND ANSWERS GRADED A+
✔✔Evolution - ✔✔_________ is the change in the inherited characteristics of biological
characteristics of populations over successive generations.
✔✔Natural Selection - ✔✔_____ _______ is the gradual process by which biological
traits become either more or less common in a population.
✔✔Heritable Traits - ✔✔Natural selection affects a population through what?
✔✔Natural Selection - ✔✔The following are necessary for what to occur?
1. Heritable variations exists in a population
2. The number of offspring that can be produced is greater than the number that are
produced
3. Not all individuals in a population are equally successful at survival and reproduction;
this differential success is at least partially due to different inherited traits in the different
individuals
✔✔T - ✔✔True or false: environmental factors can be agents of natural selection
✔✔Relative Fitness - ✔✔Measurement for how well individuals with certain traits
survive and reproduce in a particular environment.
✔✔Cumulative - ✔✔Is evolution better represented by the single-step or cumulative
model?
✔✔Biodiversity - ✔✔_____ is due to evolution and natural selection. Without it we
would all be the same.
✔✔Phylogeny - ✔✔The hypothesized evolutionary relationships between species.
✔✔Taxonomy - ✔✔The classification of organisms into groups (identifying and naming).
✔✔Cladistics - ✔✔A method of classification of organisms according to the proportion of
measurable characteristics that they have in common.
✔✔DKPCOFGS - ✔✔Hierarchy of classification of life (acronym)
✔✔Bacteria Archea Eukarya - ✔✔Three Domain Classification system
✔✔Homologous - ✔✔"of the same" ... sharing characteristics of structure
, ✔✔Analogous - ✔✔"different" ... not being the same at all
✔✔Observation Hypothesis Experiment Conclusion - ✔✔What is the proper order for
the steps of a scientific study?
✔✔F - ✔✔True or false: life does not change over long time periods
✔✔T - ✔✔True or false: life requires energy
✔✔T - ✔✔True or false: life maintains internal environment at constant levels
✔✔T - ✔✔True or false: life reproduces itself
✔✔T - ✔✔True or false: life is more organized than it's environment
✔✔disprove a hypothesis - ✔✔Scientific experiments are designed to try to
_________________________.
✔✔Theory - ✔✔A hypothesis that has been tested many times and all evidence
supports it.
✔✔Evolution - ✔✔A change occurring over time in a line of descent.
✔✔T - ✔✔True or false: Natural Selection can lead to Evolution
✔✔F - ✔✔True or false: Natural Selection is random and Evolution works toward a goal
✔✔F - ✔✔True or false: Natural Selection and Evolution are different terms for the
same process
✔✔Homologous - ✔✔The forelimbs bones of vertebrates are an example of what type
of structures?
✔✔Horizontal - ✔✔______ transfer increases the speed with which anti-biotic resistant
strains of bacteria adapt.
✔✔genus; species - ✔✔Homo sapiens is an example of what?
✔✔Eukarya - ✔✔To what Domain do you, as a human, belong?
✔✔phylogenetic tree - ✔✔A ________ ___ consists of hypothesized evolutionary
relationships among groups of organisms.
