BIO 121: FINAL EXAM REVIEW WITH
CORRECT ANSWERS 2024
Evolution - correct answers-change overtime
Biological evolution - correct answers-consists of genetic change in populations of
organisms across generations
The two naturalists from England who established the idea of natural selection - correct
answers-1. Alfred Russell Wallace
2.Charles Darwin
Where Alfred studied natural selection - correct answers-Archipelago
Where Charles Darwin studied natural selection - correct answers-on his voyage of
HMS Beagle
HMS Beagle - correct answers-Charles Darwins book published that explained his belief
of natural selection
Natural Selection - correct answers-process by which inherited characteristics enhance
survival reproduction
3 premises of natural selection - correct answers-1. Organisms face a constant struggle
to survive and reproduce
2. Organisms tend to produce more offspring than can survive
3. Individuals of a species vary in their characteristics
Adaptive traits - correct answers-genes are passed to offspring and those of better
adapted parents will succeed because they will better adapt through time
Adaption - correct answers-trait that promotes success
Artificial selection - correct answers-selection conducted under human direction
Examples of artificial selection - correct answers-1.dog breeding
2.plant breeding (broccoli, cauliflower, brussel sprouts)
Speciation - correct answers-process in which new species are generated
, Allopatric speciation - correct answers-species formation due to physical separation of
populations over geographic distance
How allopatric speciation works - correct answers-other DNA combines with other
species and mutations begin to form
Phylogenetic Trees - correct answers-depict relationships among species, major groups
of species, populations, or genes
Extinction - correct answers-the disappearance of a species from earth
Why extinction is a natural process - correct answers-when conditions naturally change
and a species does not have enough time to adapt and work with the change
Example of extinction as a natural process - correct answers-rise&fall of sea level,
arrival of new species, severe weather events
Mass extinction events - correct answers-massive disappearance of species at once
What mass extinction our world is in currently - correct answers-6th mass extinction
event due to human impact
Ecology - correct answers-study of interactions among organisms and between
organisms and their environment
Ecological levels of organization - correct answers-1. Biosphere
2. Ecosystem
3. Community
4. Population
5. Organism
Key concepts of ecology - correct answers-1.habitat
2. Niche
Habitat - correct answers-consists of living and non-living elements around the
organism (which is scale dependent)
Niche - correct answers-reflects the use of resources and its functional role in a
community
