BIO 250 EXAM 1 WITH ALL CORRECT & VERIFIED
ANSWERS (UPDATED TO PASS)
Evolution is the unifying concept of biology Correct answer-Dobzhansky
Ophelia Syndrome Correct answer-Being told what to do or how to think; Thomas Plummer
What are the six cures to Ophelia Syndrome? Correct answer-1. Seek out great teachers
2. Dare to know and trust yourself
3. Learn to live with uncertainty (Science exists because of what we don't know)
4. Practice dialectical thinking; Put yourself in their shoes
5. Foster idle thinking (Alfred Russel Wallace codiscovered natural selection while sick in a bed in
Malay)
6. Plan to step out of bounds (Question presumed bounds of thinking, reading, writing, or learning)
Theory of Evolution Correct answer-the idea that all species are related and gradually change over
time
What are the 7 evidences for Evolution? Correct answer-1. Nested hierarchical structure of life
(Gave rise to binomial nomenclature)
2.Evidence for extinction
3. Succession of fossil types
4. Geographical relationships of similar species (Sarawak law) - Similar species come from similar
places
5. Shared embryonic features (Haeckel)
6. Common design blueprints for structures with different function (homologous structures)
7. Vestigial organs -- appendix (loss of function, not loss of structure) & Atavisms -- tail (ancestral trait
reappears)
binomial nomenclature Correct answer-Carolus Linnaeus
classification based on shared similarities
Thomas Molyneux Correct answer-First to describe extinct irish elk
Cuvier Correct answer-list of 23 extinct species in 1801
Charles Lyell Correct answer-proponent of uniformitarianism
Uniformitarianism Correct answer-geologic processes have not changed throughout Earth's history.
Lyell's Principles of Succession Correct answer-1. Superposition: bottom layers older than top
layers
2. cross cutting structure is younger than layer it crosses
3. structure included is older than structure holding it
4. Original horizontality
5. Uniformitarianism
Wallace's Line Correct answer-a faunal boundary line drawn in 1859 by the British naturalist Alfred
Russel Wallace that separates the ecozones of Asia and Wallacea, a transitional zone between Asia
and Australia.
, Richard Owen Correct answer-Structural homology
What is the difference between natural selection and evolution? Correct answer-NS acts on
individuals, evo takes into account populations
Darwin's 2 ideas Correct answer-1. Tree-thinking (evolution)
2. Natural selection (hypothesis for how evolution occurs)
Identity by descent Correct answer-homology (phylogenetic trees)
Identity by convergence Correct answer-analogy
consilience of induction Correct answer-one class of facts coincides with an induction obtained
from a different class
What did John Snow do? Correct answer-cholera epidemic, traced source to water pump on broad
street
Germ theory Correct answer-the theory that infectious diseases are caused by certain microbes
Pasteur
Tokogeny Correct answer-Ancestor-dependent relationship (family evolution)
Phylogeny Correct answer-species-level evolutionary history
Proximate cause Correct answer-occur during the lifespan of organism
how questions
physiology of raising body temperature
ultimate cause Correct answer-operate during evolutionary history of organism
why questions
why do we have a febrile response to infection
Characterization of host-pathogen conflict Correct answer-evolutionary arms race
complex immune system vs rapid reproduction and high mutation rate
Antibiotics Correct answer-strong agents of selection selecting for resistance.
highly resistant bacteria have low fitness compared to susceptible bacteria
Virulence (why pathogen harm hosts) Correct answer-A pathogen/microbe's ability to infect or
damage a host
1. coincidental evolution
2. short-sighed evolution
