BIO 150 Exam 1 Hyman QUESTIONS WITH
|\ |\ |\ |\ |\ |\
ANSWERS
|\
What is the difference between correlation and causation?
|\ |\ |\ |\ |\ |\ |\
- CORRECT ANSWERS ✔✔- Correlation means there is a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
relationship, but one does not inherently cause the other
|\ |\ |\ |\ |\ |\ |\ |\ |\
to change |\ |\
- Causation indicates that one event is the result of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
occurrence of the other event |\ |\ |\ |\
What type of studies/experiments determine causation? -
|\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔Experimental studies
|\ |\ |\
What type of studies/experiments does not determine
|\ |\ |\ |\ |\ |\ |\
causation, but tests a hypothesis? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\
✔✔Non-experimental studies |\
What type of studies/experiments neither determine
|\ |\ |\ |\ |\ |\
causation nor test a hypothesis, but merely makes
|\ |\ |\ |\ |\ |\ |\ |\
observations? - CORRECT ANSWERS ✔✔Descriptive |\ |\ |\ |\ |\
studies
,How does one read a phylogenetic tree? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔- Taxa are the group of organisms placed at
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the tips of the branches
|\ |\ |\ |\ |\
- Nodes are branch points that represent common
|\ |\ |\ |\ |\ |\ |\ |\
ancestors |\
- Nodes can rotate and mean the same thing
|\ |\ |\ |\ |\ |\ |\ |\ |\
- Branches are the lineages of organisms
|\ |\ |\ |\ |\ |\
Define biodiversity: - CORRECT ANSWERS ✔✔"a tree of
|\ |\ |\ |\ |\ |\ |\ |\
life" describing all of life's evolutionary relationships
|\ |\ |\ |\ |\ |\
What are 3 ways biodiversity can be measured? -
|\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔- Taxonomic species diversity
|\ |\ |\ |\ |\
- Genetic diversity
|\ |\
- Functional diversity
|\ |\
What are the two components measured in taxonomic
|\ |\ |\ |\ |\ |\ |\ |\
species diversity? - CORRECT ANSWERS ✔✔- the total
|\ |\ |\ |\ |\ |\ |\ |\
number of species in an area (species richness)
|\ |\ |\ |\ |\ |\ |\
- some abundance weighted measure (shannon diversity
|\ |\ |\ |\ |\ |\ |\
index)
Typically a greater abundance of species (higher shannon
|\ |\ |\ |\ |\ |\ |\ |\
diversity) indicates a _______ system - CORRECT
|\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔healthier |\ |\
,Ex. Community 1 is "healthier" than Community 2
|\ |\ |\ |\ |\ |\ |\
What is genetic diversity? - CORRECT ANSWERS ✔✔the
|\ |\ |\ |\ |\ |\ |\ |\
total genetic information contained within all individuals
|\ |\ |\ |\ |\ |\ |\
of a population, species, or a group of species
|\ |\ |\ |\ |\ |\ |\ |\ |\
- just 1 individual doesn't capture all the genetic diversity
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
within the species |\ |\
Typically maintaining greater genetic diversity is better.
|\ |\ |\ |\ |\ |\ |\
Why? - CORRECT ANSWERS ✔✔leads to less inbreeding
|\ |\ |\ |\ |\ |\ |\
What is functional diversity? - CORRECT ANSWERS ✔✔the
|\ |\ |\ |\ |\ |\ |\ |\
elements of biodiversity that influence how an ecosystem |\ |\ |\ |\ |\ |\ |\ |\
functions |\
- species have "functional roles" in an ecosystem Ex.
|\ |\ |\ |\ |\ |\ |\ |\ |\
pollinator, N-fixer, photosynthesizer |\ |\
What are the current trends in biodiversity? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔- species are vanishing faster than at |\ |\ |\ |\ |\ |\ |\ |\
virtually any other time in Earth's history |\ |\ |\ |\ |\ |\
- modern rates of extinction are 100 to 1000 times
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
greater than the average or background rate |\ |\ |\ |\ |\ |\
- estimated losses of 5000-25000 species per year
|\ |\ |\ |\ |\ |\ |\
, What taxonomic groups have the most named species? -
|\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔Vertebrates and non-vertebrates
|\ |\ |\ |\
Which taxonomic group is the most threatened? -
|\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔amphibians |\ |\
What taxonomic groups are we lacking information
|\ |\ |\ |\ |\ |\ |\
about? - CORRECT ANSWERS ✔✔Microscopic groups
|\ |\ |\ |\ |\ |\
(bacteria, fungi) |\
Why is biodiversity important to humans? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔"It's the bolts holding together airplane
|\ |\ |\ |\ |\ |\ |\
earth"
Examples: |\
- We depend on diverse species for flower pollination
|\ |\ |\ |\ |\ |\ |\ |\
- Biodiversity helps create medicines
|\ |\ |\ |\
- Used for food and goods for the global economy
|\ |\ |\ |\ |\ |\ |\ |\ |\
- Helps to make chemicals for industrial products
|\ |\ |\ |\ |\ |\ |\
What is the Provisioning type of ecosystem services?
|\ |\ |\ |\ |\ |\ |\ |\
Provide an example - CORRECT ANSWERS ✔✔provides
|\ |\ |\ |\ |\ |\ |\
raw materials
|\
- food, fuel, fiber, medicines, genetic resources
|\ |\ |\ |\ |\ |\
