Transcript Ch 1 PPT - Ludlow Independent Schools

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.

Controlled Experiment
• Control Group –
• Experimental Group –
• Qualitative Data –
• Quantitative Data –
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.
