- Carbon Dioxide
- C6H12O6
- sugar/glucose
- O2
- Oxygen
- Photo Synthesis
-
Water+Carbon Dioxide = Sugar+Oxygen
Cellular Respiration - Aerobic Respiration
-
Sugar+Oxygen=Carbon Dioxide+Water+Energy
Opposite of Photo Synthesis - All Living things need....
-
CHNOPS
Carbon

Sulfur - Define Biology
- The study of life
- Homeostasis
- Maintaining a constant internal environment
- Two forms of metabolism are:
-
Photo Synthesis
Aerobic Respiration -
Complete this statement:
A living thing_____ and ______, ______,
uses _______ and contains _______. - A living thing grows and develops, reproduces, uses energy, and contains DNA.
-
Meter=
Liter=
Gram= -
Length
Volume
Mass - Density
- mass/volume
- How to measure water
- 1ml= 1cm to the power of 3= 1g
- median
- middle value of ordered values
- range
- highest to lowest
- mean
- sum of values/number of values
-
T/F
For 15 grams the metric symbol would be shown 15 gs -
F
15g
all symbols are singular and with no space. - Control group
- The group that does not receive the "treatment" being studied.
- Francesco Redi... Who is he?
- In 1668 Francesco Redi performed what is thought to be the 1st real experiment using the scientific method. In his time the popular belief was that things reproduced from spontaneous regeneration, and that flies were created from rotting meat. Redi Hypothesized that this was not so and his experiment proved that flies are not created from rotting meat.
-
T/F
A hypothesis cannot be proved true. -
T
A hypothesis can only be proved false. - Ethology
- The study of animal behavior
- Behavior is defined in this course as...
- Any observable muscular response to some stimulus.
- A fixed, naturally occurring behavior without being learned is _________.
- innate
- Name three things that demonstrate how certain behaviors are innate (a product of genes).
-
Deprivation Experiments
The behavior occurs immediately after birth.
Hybrid (cross-breeding) Experiments - Habituation
- A decrease in response to a repeated stimulus.
- Associative Learning
- an association is formed between the stimulus and response or between two stimuli. Behavior is conditioned through association.
- Classical Conditioning
-
AKA Pavlovian Conditioning
Association formed between 2 stimuli. - Operant Conditioning
-
Association between behavior and reward/ punishment.
(Skinners rat Box) - Ecology
- The study of how organisms interact with each other and with the "physical" environment.
- Ecosystem
- community different species interacting with one another and non-living environment (matter & energy)
- Every ecosystem is characterized by ______ flow and ________ cycling.
-
energy flow
chemical cycling - Energy flow is based on two laws of thermodynamics, what are they?
-
1) Energy cannot be created or destroyed.
2) When energy is transformed from one form to another some of it is converted into usable energy as heat. - autotroph
-
producer
self feeder
plants
algae
etc. - consumers
-

omnivore
decomposer - herbivore
- primary consumer... eats plants
- carnivore
-
secondary or tertiary consumer
eats meat - omnivore
- eats plants & meat
- decomposer
-
decomposes
beetles
worms
fungus
etc. - 1st trophic level
- producers (autotrophs)
- 2nd trophic level
- primary consumers (herbivores)
- 3rd trophic level
- secondary consumers (carnivores)
- 4th trophic level
- tertiary consumers (top carnivores)
- Food chains become _______ ________.
- Food chains become food webs.
- What is a trophic level?
- feeding level
- How do populations in undisturbed ecosystems maintain their size?
-
limited food supply
competition
predation
parasitism - population pyramid of numbers
- amount of organisms at each trophic level
- population pyramid of biomass
- weight of living matter at a particular time
- population pyramid of energy
- decrease of energy at each trophic level
