Basic Concept
Scientific Method |
1. Observe phenomena and formulate testable and falsifiable hypothesis.
2. Test hypotheses, collect data, and analyze statistically. |
|
|
What is life?
|
Characteristics: metabolism, reprocution, growth, movement, responsiveness, complex organization.
|
|
|
Evolution
|
Concept that all organisms are related to each other by common ancestry.
|
|
|
Evolution
Natural Selection |
A mechanism fo rthe occurrence of evolution
1. survival of those offspring best adapted to the conditoins in which they live: a. individuals produce sexually many more offspring than could possibly survive. b. These offspring are not identical but show variations based on genetic differences. c. The variations help t hem to survive to the age of reproduction , so that they cnan pass their genes to the next generation. |
