What is misleading about this graph?
the long x axis time period
the short x axis time period
the broad range on the y axis
the narrow range on the y axis
When does global CO2 go down each year?
during June, July, and August
during April, May and June
From June to November
From November to May
What are two true but misleading statements about this graph?
carbon dioxide levels go down each year
carbon dioxide levels only go up about 2-4 ppm each year overall
carbon dioxide goes up more than it goes down each year
the low for one year is higher than the low for the year before
What is the main pattern of this graph?
the increases are more than the decreases
the decreases are more than the increases
the increase and decrease in CO2 maintain an equilibrium
What type of data was used to generate the carbon dioxide data before 1958?
Observations from Mauna Loa
Observations from ice core data
Observations from fossils
Observations from sophisticated telescopes
Where is Mauna Loa?
Near a city in Hawaii
In a remote location away from cities
Near an industrial complex
What is the significance of Mauna Loa's location? (two reasons)
It is not impacted by a single source of carbon dioxide
It is impacted by global carbon dioxide changes
It can measure the changes based on commuting cars in Honohulu
In can measure the impact of a large factory in Hawaii
What a true but MISLEADING statement about this graph?
Don't worry about CO2 levels now, they naturally go up and down
CO2 levels are much higher now than they have ever been in 800k years
What is wrong with the statement...Don't worry about CO2 levels now, they naturally go up and down
CO2 levels have never been nearly this high in the 800,000 years of past measurements
The natural highs are about the same the as current high
There is nothing wrong with this statement
Why are carp being marketed as copi? (3 answers)
To try to get people to eat more of them
Because they used to be called Kentucky Tuna, and didn't sell well
Copi is a shortened form of copious, meaning there are a lot of these carp out there
Because copi means rare, and these makes these even more desirable.
How did invasive asian carp originally get out of ponds?
an earthquake
a flood
irresponsible fishing practices
kids catching them with their hands and tossing them in a river
Why were asian carp originally introduced to the United States?
To keep algae/seaweed under control in ponds
To eat round goby to reduce their populations
They are delicious and people wanted to fish for them
To keep the salmon population under control
Estimate the % of Carbon dioxide you exhale.
0.5%-3%
30-40%
50-60%
99-100%
Which cell part uses the oxygen you breathe in, and then also releases CO2 from larger molecules?
chloroplast
mitochondria
nucleus
ribosomes
What was the purpose of seeking to rename Asian carp into Kentucky Tuna in 2018? (two selections)
increase human demand to consume Asian Carp
decrease human demand to consume Asian carp
reduce the population of an invasive species
increase the population of an invasive species
What are the three most direct reasons for the large increase in global CO2?
burning oil
burning coal
humans breathing
burning gasoline

Hint: Monomer = a single unit
carbohydrate
monosaccharide

nucleotide
The "lock and key" description explain the mechanism of
enzyme specificity
how temperature works
exocytosis
vacuole formation
The reactants to which enzymes bind are also known as
lipids
reactions
controls
substrates
Which enzyme would you expect to find in bacteria growing in a hot environment?
Enzyme X
Enzyme Y
Using the diagram, match the following.
A

A stoma is
an opening
a clot
a cell that captures light energy
a water tube
The main function of stomata is to
capture sunlight
protect leaves from insects
allow gases to move rapidly in/out of leaves
release sugars into the atmosphere
