Discovery Science
Recorded Observations(data)
Hypothesis-Based Science
Idea->Hypothesis->Test
What is a hypothesis
Falsifiable Statement
- designed to be tested
- if false, good experiment will prove falsehood
-disprove things that aren’t true
Tiny to enormous
- Atom
- Molecule
- Macromolecule
- Organelle
- Cell

Atom
Smallest unit if an element; something that can’t be broken down w/o changing what it is.
Oxygen
Molecule
1+ atoms joined together
Dioxide
Macromolecule
Large molecule built of smaller molecules
Amino Acid
Organelle
Structure inside cell that carries specific function
Mitocondria
Cell
Smallest unit of life
skin cell
Tissue
Cells working together in single process
Muscle Tissue
Organ
Structure made from tissue that performs specific job for individual
Lung
Organ system
Organs with related function in an individual
Respiratory system
Individual
Single complete organism
Lion
Population
All members of species in 1 location
Lion Pride
Community
All populations in 1 location
Lions and Zebras
Ecosystem
Community + non living environment factors”
Serrengeti
Biosphere
Everywhere life exists on, beneath, or above earth
Life on Earth
Emergent Properties
Properties that manifest that emerge when you put smaller things together that you couldn’t predict from those smaller parts
Reductionism
When we study one part of a piece to understand large process
Systems Biology
Create models of dynamic behavior of whole bio systems
Define entropy
Measure of disorder
Homeostatis
Living things keep same internal conditions ( to maintain ordered structure)
Negative Feedback
End result of process that uses pathway serves as signal to turn off whole process
Positive Feedback
End result of pathway process signals beginning to produce more of final result
