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.
