Are fossil fuels renewable or nonrenewable?
Nonrenewable
What is the charge of each: proton, neutron, electron?
Proton +

From the surface to the center, list the 4 major layers of the Earth.
Crust, Mantle, Outer Core, Inner Core
Are specialists or generalists more susceptible to extinction?
specialists
List the levels of classification in order from most inclusive to most specific.
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
List 2 nonrenewable resources.
minerals, metals, coal, oil...
You measure the pH of a river to be 7.70 Is this best described as: very basic, very acidic, slightly basic, or slightly acidic?
Slightly basic
What happens at a divergent plate boundary?
Plates pull apart
What is artificial selection? Give an example.
Humans breeding organisms for specific traits - dogs
What biological process is summarized with the chemical equation:
C6H12O6 + 6O2 --> 6CO2 + 6H2O
Cellular Respiration
Explain how groundwater could be considered either a renewable or nonrenewable resource.
depends on rate of withdrawl
Explain why water expands when it freezes.
Each molecule must distance itself from others to satisfy hydrogen bonds. When in a liquid state, molecules can be more closely packed as the hydrogen bonds will be transient.
Which is more dense, outer core or crust?
Outer core
Give 3 examples of pressures that prevent a population from exceeding carrying capacity.
competition for food, competition for habitat, parasites, disease transmission...
What term describes the shape of a leaf’s edge?
margin
Give 3 examples of ecosystem services.
pollination, pest population control, water purification, erosion control, groundwater recharge...
Why are some isotopes radioactive and others are not?
Some combinations of nucleons are unstable, these isotopes are radioactive.
At what type of plate boundary would you expect mountains, but not volcanoes?
Convergent Collision
Use a population of rabbits to explain how natural selection can lead to evolution.
Must identify variation, competition, survival, reproduction resulting in change in allele frequency
How is water’s capacity to hold dissolved oxygen related to temperature?
Besides “# of Earths” in what other unit did you calculate your ecological footprint?
Global hectares (gha)
How many neutrons are in an atom of Copper-65?
36
65-29 = 36
The Nazca Plate is an oceanic plate on the Western side of South America, what direction is it moving?
East
Explain the difference between exponential and logistic growth. What conditions lead to each?
Exponential - growth increases every year. Happens when resources are plentiful Logistic - population plateaus at carrying capacity. Happens when population pressures limit growth.
If we were to live sustainably, how many gha would every human be allotted?
1.6 - 1.7 gha
