homeostasis
Maintains a stable internal state
negative feedback
returns body to a setpoint
returns body to the normal temperature
How is thermoregulation an example of negative feedback?
positive feedback
Takes body away from setpoint
fever, lactation, childbirth, blood clotting
What is an example of positive feedback
6CO2 + 6H2O -> C6H12O6 + 6O2
equation for photosynthesis

cellular respiration equation
C6H12O6 + 6O2
reactants of cellular respiration
6H2O + 6CO2
products of cellular respiration
allows ATP synthesis in the absence of oxygen
What is fermentation?
animals
What organisms do lactic acid fermentation?
yeast
What organisms do alcohol fermentation?
It releases stored energy that is used to make ATP
Why is glucose necessary to make ATP?
To provide energy for cellular respiration
Why do we need to eat?
To provide O2 to run the ETC of cellular respiration
Why do we need to breathe?
It reduces CO2 in the atmosphere by putting it into photosynthesis
How does photo synthesis affect the carbon cycle?
It increases CO2 in the atmosphere
How does the burning of fossil fuels affect the carbon cycle?
A place where carbon is stored
What is a carbon sink?
The sun
Where does most energy for life come from?
producers, primary consumers, secondary consumers, tertiary consumers
List the trophic levels from most energy to least energy
There is less energy available at higher trophic levels to support organisms
Why are there usually less tertiary consumers in an area than there are producers
Caron dioxide traps heat in the atmosphere
How does the amount of CO2 in the atmosphere impact global warming?
O2 is a product in photosynthesis and a reactant in cellular respiration
How does oxygen link photosynthesis and cellular respiration?
question, hypothesis, experiment, observation, analysis, conclusion
Steps of the scientific method
independent variable
variable that is manipulated
dependent variable
variable that is measured
supported by much evidence
theory
control group
a basis for comparison
constants
variable that do not change in an experiment
