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.
