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.

Reasoning Induction Deduction

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.
