16
BONUS QUESTION 1: Why are dalmatians the traditional dog of choice for fire stations?
Superior endurance let them keep up with the fire carriages
Their coloring makes them stand out in smoky areas.
They bonded well with horses that once pulled fire carriages
Deafness, common in them, meant sirens don't hurt their ears
17

21
What are the two primary sources of energy that power living systems?
Light and Thermal Energy
Light and Chemical Energy
Wind and Thermal Energy
Nuclear and Fossil Fuels
22
The first step in releasing the energy of glucose in the cell is known as
glycolysis
electron transport
fermentation
the Krebs cycle
23
Cells use the energy available in food to make a final energy-rich compound called:
Water
Glucose
ADP
ATP
24
Which is used by cells to store and release the energy needed to power cellular processes?
DNA
ATP
Carbon Dioxide
Water
25
Which group of organisms is always found at the base of a food chain or food web?
Primary producers
Primary consumers
Tertiary consumers
Secondary consumers
26
The series of steps in which a large fish eats a small fish that has eaten algae is a
food chain
food web
pyramid of biomass
pyramid of numbers
27
How many ATP molecules are produced during the Krebs Cycle?
2
1
4
0
28
During the Krebs cycle:
a glucose molecule is split into 2 molecules of pyruvic acid
hydrogen ions and oxygen form water
the cell releases a small amount of energy via fermentation
pyruvic acid breaks down into CO2 via a series of reactions
29
What type of cells might carry out chemosynthesis?
Bacteria
Animal cells
No currently living organisms use chemosynthesis
Plant cells
30
Which is one source of energy for chemosynthesis in certain living organisms?
Hydrogen sulfide
Sunlight
Cyanide
Mushrooms
31
What compound must be taken in by plants to drive the Calvin Cycle?
Hydrogen Sulfide
Water
Oxygen
Carbon Dioxide
32
What is a waste product of the light-dependent reaction?
ATP
NADPH
Carbon Dioxide
Oxygen
33
How can ATP easily release and store energy?
By pumping protons across a membrane, creating a gradient
By holding and transporting 2 high energy electrons
By breaking off or adding on the third phosphate group
By absorbing energy from the sun and releasing electrons
34
BONUS QUESTION 5: Why are summer vacations a thing?
July/August were traditional vacation months for families
It unified urban and rural school schedules in the mid 1800s
In early America kids were needed to work farms in summers
Rural schools couldn't get good teachers in the summer
35
