Populations
rapid population growth. High birth rate and falling death rate
responsible for naming the 6 criteria air pollutants and regulating these pollutants to ensure we have access to clean air in the US.
Clean Air Act
the amplification of a toxin within organisms from one trophic level to the next
biomagnification
2 examples of renewable energy resources

What item made up the core of Harry Potter's wand?
Phoenix Feather
How do you calculate total population change? (hint: there are 4 factors in this equation)
(birth rate + immigration)-(death rate + emigration)
responsible for limiting hydrocarbons and NOx emitted from gas powered automobiles
catalytic converters
2 molecules responsible for eutrophication
nitrates and phosphates
Describe the human health impacts of mercury exposure/contamination
damages CNS
What month is Earth closest to the Sun?
January
explain why population growth slows in stage 3 of the demographic transition
birth rate falls due to increased access to education, family planning, and contraceptives
write the equation for the formation of acid rain. You must also provide the source for the criteria pollutant involved in the equation.
SO2 + water vapor -> sulfuric acid (H2SO4)
NOx + water vapor -> nitric acid (HNO3)
From burning coal/oil/vehicle exhaust
In the tertiary treatment phase at a WWTP, give 2 examples of how bacteria is "removed" before water is discharged back into the environment
chlorination, O3, UV light, Reverse Osmosis
Greenhouse gas emitted from burning fossil fuels that has a GWP = 1.
CO2
Name the scientist responsible for discovering the negative health and environmental impacts of DDT
Rachel Carson
A country's population is growing rapidly. Give an example of a realistic and effective solution to slow population growth
tax incentives/punishment for having children, increased education access, increased access to contraceptives/family planning,
name the 6 criteria pollutants

This act requires the EPA to regulate pollutants that will cause negative public health effects. Requires protection of drinking water sources.
Safe Drinking Water Act 1974
Uranium has a half life of 700 years. How much of a 12g sample will remain after 2100 years?
1.5g
Write the formula for cellular respiration
glucose + oxygen -> energy + CO2 + H20
70/5% = 14 years
Write the equation for the formation of ground level ozone
NOx + VOCs + sunlight -> ground level ozone
Describe how runoff from an agricultural field can result in a fish kill.
excess nutrients enter water system --> eutrophication --> algae bloom and die off --> decreased DO
Increased turbidity --> increased water temp and reduced photosynthesis --> decreased DO
what is the most likely negative environmental impact from a nuclear power plant?
thermal pollution
Who is considered the oldest living being in Middle Earth?
