Why are environmental problems often called wicked problems?
Potential solutions almost always create additional problems

the tragedy of the commons
Which of the following is NOT a question suitable for scientific inquiry?
Is it ethical to put heavily polluting industries in low-income neighborhoods?
Bats found with white-nose syndrome appeared to die because:
the fungal infection caused them to wake more often and use up their fat reserves, so they died of starvation
Scientists avoid saying that a theory has been proven because:
It suggests that we have the final answer. AND Alternative hypotheses may turn out to have stronger support.
In an observational study
Researchers gather data in a real world setting without manipulating conditions.AND Researchers test whether their data fit predictions generated by a hypothesis.
In an experiment, the control group is used to:
Provide a baseline for comparison with the test group
If I find dead frogs in Australia infected with chytrid fungus, and in South America, and in North America, I could infer that chytrid fungus is related to global frog declines. This would be an example of
inductive reasoning
Which of these statements is correct?
If the data contradict the predictions of the hypothesis, that hypothesis has been falsified
What scientific topics do you think have a bit of a "certainty mismatch" between scientists and lay people? Write in:
Climate Change, Evolution, Dietary Supplements, Radiometric dating,
What kind of organisms are on trophic level TL 3?
Secondary consumer
biodiversity communities have
high species richness and high species evenness
Butterflies visit flowers to drink nectar. They also pollinate the flowers. The relationship between the butterfly and flower is:
mutalism
Keystone species:
Are particularly important for the survival of other species in the community
What trait determines whether a toxin is likely to bioaccumulate in an individual
Whether it is fat or water soluble
Which of the following is an example of a secondary source of information?
A Scientific American article that reviews the Nature article
LD-50
where 50% of population is killed off

To logically assess the quality of information or a claim, we should do all of the following EXCEPT

In 2012 the FDA banned the use of BPA in infant sippy cups and baby food jars, even though there was still some disagreement between studies as to whether BPA is actually toxic in humans. This is an example of:
the precautionary principle
When toxic substances act synergistically
the total effect is greater than the sum of the individual effects
Which of these are in the world's top 10 most populous countries
India, United States, Brazil, Indonesia
Nigeria has high population momentum
The age structure is biased towards young people who have not entered reproductive age
Which of these usually happens FIRST in the demographic transition?
death rates fall
What generally happens to a population's total fertility rate (TFR) when infant mortality (death) rates decreases?
it decreases
Carrying capacity
depends on resource availability
Why does high infant mortality increase population growth rather than decrease it?
Due to infant mortality, it causes parents to feel they need to have more children to compensate if they do not survive.
Which of these lists represents the levels of ecological organization from smallest to largest?
Population, Community, Ecosystem
Why must Earth receive a constant input of solar energy to fuel life?
Energy cannot be recycled - it is lost as heat as it passes from one organism to another
Biomes are defined as distinctive types of ecosystems determined and identified by
Climatic factors such as precipitation and temperature AND The predominant plants and other organisms that live there.
The range of tolerance for a species identifies things like the:
highest and lowest temperatures that individuals of a population can withstand.
What is the purpose of cellular respiration, a part of the carbon cycle?
It is a way to release the chemical energy of a sugar molecule.
