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.

|
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. |
