Study Guide Final Semester I V. B

cells, tissues, organs, organ systems
levels of organization
Take in O2, transport it, remove CO2
How do the respiratory systme and circulatory systems interact to supply O2 to the body
Transport O2 and nutrients, remove CO2
Function of Circulatory System
Heart, veins, arteries
Organs of Circulatory System
break down and absorb nutrients
Organs of Digestive System
Regulate growth, development, homeostasis
Function of Endocrine system
Organs of Endocrine system
Remove waste
Function of Excretory System
Acts as a barrier, excretes waste
Function of Integumentary Sytem
Skin, hair, nails
Organs of Integumentary System
Kidneys, bladder
Organs of Excretory System
Function of Muscular System
Organs of Muscular System
Responds to Environment
Function of Nervous System
Nerves, brain, spinal cord
Organs of Nervous System
Lungs, trachea
Organs of Respiratory System
Bring in O2, remove CO2
Function of respiratory system
Structural support, allows movement
Function of Skeletal System
bones, cartilage
Skeletal System
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
6CO2 and 6H2O
reactants of photosynthesis
C6H12O6 + 6O2
products of photosynthesis
Organelle that carries out photosynthesis
How is the chemical energy from photosynthesis stored?
Monomer of a carbohydrate
function of carbohydrates
amino acid
monomer of a protein
makes your body
function of proteins
fatty acids and glycerol
Building Blocks of Lipids
energy storage
function of lipids
monomer of nucleic acids
genetic information
nucleic acid
C6H12O6 + 6O2 -> 6CO2 + 6H2O
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?
What organisms do lactic acid fermentation?
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
control group
a basis for comparison
variable that do not change in an experiment
