1. Order
Order• Analyzing a biological structure
gives us clues about what it does and how it works
2. Reproduction
• DNA:
• Genes:
• Genome:
3. Growth & Development
• Organisms increase in size and complexity.
• Growth –
• Development -
• Life -
4. Energy Utilization
5. Response To Environment
• The speed of the response may be “fast” or “slow”.
6. Homeostasis
• “homeo” = same “stasis” = state
• Negative Feedback:
• Positive feedback:
7. Evolutionary Adaptation
• Natural Selection:
Science is based on:
1)
2)
3)
Observations:
• Are the “keystone” to Science.• If it can’t be “observed”, it can’t be studied by the
Scientific Method.• Can be made through your senses or through
the use of tools.
• Inquiry –
• Discovery Science –
• Hypothesis –
• Theory –
Scientific Method:
• Outlines a series of steps for answering questions.
• Obtains “evidence” through the use of experiments.

Summary
• We will see the “themes” at various times throughout the course.
• AP Biology students must be able to design an experiment to test a hypothesis.
• Why? This is a national exam test item.
